Email Settings GuideQuick answer: a Zoho Workplace mailbox on a custom domain uses imappro.zoho.com on port 993 with SSL. The SMTP server is smtppro.zoho.com on port 465 SSL or 587 STARTTLS. The POP server is poppro.zoho.com on port 995 SSL. Swap the .com suffix for your data center where needed, such as .eu or .in. Sign in with your full you@yourdomain.com address. With two-factor on, use an app password.
What Changed Recently#
Zoho splits its mail servers by account type and by data center. Here is what that means for a Workplace client setup today.
Latest update
Workplace accounts use the pro hosts. A custom domain mailbox connects through imappro.zoho.com and smtppro.zoho.com. The personal imap.zoho.com host rejects a paid organization login.
Earlier change
The host suffix follows your data center. An account created on the EU servers uses imappro.zoho.eu and smtppro.zoho.eu. The US hosts reject those credentials even when they are right.
Earlier change
IMAP and POP need turning on first. Zoho keeps both off by default. Enable them in webmail before any client will connect.
you@yourdomain.com address and an app password when two-factor is on.
Before You Begin#
Two things decide whether Zoho Workplace connects on the first try. Handle them and the tables below do the rest.
1. Turn on IMAP or POP access
Zoho keeps client access off until you switch it on. Until then no app will connect, whatever server values you type.
Where: Enable IMAP steps below →
2. Make an app password if two-factor is on
With two-factor turned on, a client cannot use your normal password. You generate a one-off app password instead.

About Zoho Workplace#
Zoho Workplace is the business email and productivity suite from Zoho, hosting domain based mailboxes for millions of organizations worldwide.
Zoho has offered hosted email since 2008 and runs data centers in several regions. The detail that shapes every client setup is twofold. A Workplace mailbox on a custom domain uses the pro hosts, imappro.zoho.com rather than imap.zoho.com. The host suffix also has to match the data center your organization sits in, whether that is the US, the EU, India, Australia or Japan.
| Service Name | Zoho Workplace Mail |
| Owned By | Zoho Corporation |
| Hosted Email Since | 2008 |
| Email Domains | Your own @yourdomain.com hosted on Zoho |
| Webmail URL | mail.zoho.com. Use mail.zoho.eu and similar by data center |
| Protocols Supported | IMAP, POP, SMTP once enabled |
| App Password Needed | Only when two-factor is on |
| Data Centers | US, EU, IN, AU, JP by region |
you@yourdomain.com connects through imappro.zoho.com, not the personal imap.zoho.com. The one thing that changes is the data center suffix, such as .eu or .in in place of .com.
Zoho Workplace Mail Webmail Login#
You can always read your mail in a browser. The official sign in pages are:
Enable IMAP and POP#
Zoho keeps IMAP and POP off until you switch them on. It takes under a minute in webmail:
- Sign in to Zoho Mail webmail at mail.zoho.com, using the address for your data center. The mobile app does not show this setting.
- Open Settings, then Mail Accounts. Pick your address.
- Find the IMAP and POP section and switch the one you want to on.
- Save. New Free plan accounts get IMAP only, since POP is held back on that tier.
.com hosts for the US region. If your organization was set up on another Zoho data center, swap the suffix on every host. EU uses imappro.zoho.eu and smtppro.zoho.eu, India uses .in, Australia uses .com.au and Japan uses .jp. A US host rejects a login from another region even when the password is right. Not sure which region you are on? Zoho shows the exact host for your account under Settings, then Mail Accounts, then your primary address, where clicking POP/IMAP or SMTP reveals the precise server names.
Zoho Workplace Mail IMAP Settings#
IMAP is the incoming protocol to pick for a Workplace mailbox. It holds mail on the Zoho server so every device shows the same inbox.
| IMAP Server | imappro.zoho.com | |
| Port | 993 | |
| Encryption | SSL required | |
| Username | Your full you@yourdomain.com address | |
| Password | Zoho password. Use an app password when two-factor is on | |
| Data center | Swap .com for .eu, .in, .com.au or .jp as needed | |
| Authentication | Required |
Zoho Workplace Mail POP3 Settings#
POP downloads mail to one machine. Choose it only if a lone local copy is what you want. New Free plan accounts do not get POP. Undecided? The comparison covers both.
| POP3 Server | poppro.zoho.com | |
| Port | 995 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full you@yourdomain.com address | |
| Password | The same Zoho or app password used for IMAP |
Zoho Workplace Mail SMTP Settings#
SMTP moves outgoing mail. When receiving works but sending will not, the fix is here.
| SMTP Server | smtppro.zoho.com | |
| Port (SSL) | 465 | |
| Port (STARTTLS) | 587 | |
| Encryption | SSL or STARTTLS (required) | |
| Username | Your full email address | |
| Password | The same password used for incoming | |
| Data center | Use smtppro.zoho.eu and the like to match your region | |
| Authentication | Required. Tick outgoing server requires authentication in your client |

Zoho Workplace Mail App Password Setup#
The most common setup failure is using the wrong password. Here is which one works where:
| Where you sign in | Regular password | App password |
|---|---|---|
| Zoho webmail and official Zoho apps | ✓ Works | ✗ Not needed |
| Outlook, Apple Mail, Thunderbird | ✗ Rejected | ✓ Required |
| Phone mail apps (manual IMAP setup) | ✗ Rejected | ✓ Required |
| Any client, with two-factor turned off | ✓ Works | Not needed |
How to Generate an App Password
- Sign in at accounts.zoho.com and open the Security page.
- Enable two-factor authentication where it is off. Zoho also calls it two-step verification. The app password choice only shows after that.
- Open App Passwords and choose to generate one.
- Name it for the app, such as Outlook or iPhone Mail, then confirm.
- Copy the code Zoho shows and paste it as the password in your mail app. Spaces in it do not matter.
Set Up Zoho Workplace Mail in Email Clients#
The pro hosts and ports do not change from app to app. The menu labels are the only thing that moves. Pick yours:
Outlook (Windows and Mac)
- Open Outlook and select File, then Add Account. The new Outlook keeps it under Settings and Accounts.
- Type your Workplace address, expand Advanced options and pick let me set up my account manually.
- Select IMAP, then
imappro.zoho.comon993SSL andsmtppro.zoho.comon465SSL. Swap the suffix for your data center. - Enter your Zoho password at the prompt. Use an app password instead if two-factor is on.
- Finish and send a test email to yourself to confirm both directions work.
Apple Mail (macOS)
- Open Mail → Settings → Accounts → Add Account.
- Zoho will not appear in the list, so pick Other Mail Account.
- Give your name, full address and password, then continue.
- If asked for servers, enter the IMAP and SMTP values from the tables above.
- Enable Mail in the checkbox list and finish.
iPhone and iPad
- Open Settings → Apps → Mail → Mail Accounts → Add Account.
- Tap Other, then Add Mail Account. iOS lists no Zoho option.
- Fill your details with the right password, then tap Next.
- Keep IMAP selected and fill the incoming and outgoing servers if iOS asks.
- Tap Save and wait for iOS to verify the account.
Android
- Open your mail app (Gmail app, Samsung Email or another) → Add account.
- Choose Other (IMAP) when your provider is not in the list.
- Provide your address and password. Should auto setup fail, choose Manual setup.
- Add the servers:
imappro.zoho.com993 SSL incoming,smtppro.zoho.com465 SSL outgoing. - Finish setup and pull down to sync your inbox.
Thunderbird
- Open Thunderbird → Account Settings → Account Actions → Add Mail Account.
- Type your name, address and password, then choose Continue.
- Let Thunderbird probe the servers, then confirm it chose IMAP over SSL.
- If detection fails, choose Configure manually and enter the table values above.
- Select Done. Folders sync on first open.
Zoho Workplace Mail Webmail Settings#
Those values wire up a client. The options here govern how the mailbox itself acts. You change them in Zoho webmail under Settings.
Signature
Set in Zoho webmail under Settings. A signature stored there rides on browser sent mail. Every client holds its own version, so the one a reader sees depends on which app sent the note.
Vacation Auto Reply
Set a start and end date on the auto reply and it switches off on its own. Zoho sends it from the server, so it answers even while your devices are shut down.
Filters and Folders
A filter built in Zoho webmail runs server side, sorting mail before any device fetches it. A rule set inside Outlook only works while Outlook is open, so two apps can route the same message differently.
Spam and Blocked Senders
Add a sender or a whole domain to the Zoho block list. If a message goes missing, check the webmail spam folder first, since a client rule cannot undo what the server already did.
POP3 vs IMAP#
| Feature | IMAP | POP3 |
|---|---|---|
| Where mail lives | On the Zoho server | Downloaded to 1 device |
| Multiple devices | ✅ Everything stays in sync | ❌ Each device sees different mail |
| Sent and deleted mail | ✅ Synced everywhere | ⚠️ Stays only on that device |
| Offline reading | ⚠️ Cached mail only | ✅ Full local copy |
| Server storage used | Yes, counts against your quota | Can be freed after download |
| Best for | Phone + computer, everyday use | Single PC, local archives |
Zoho Workplace Settings Worth Knowing#
These are the connection points that decide a Zoho Workplace client setup:
| Incoming server | imappro.zoho.com 993, poppro.zoho.com 995, SSL |
| Outgoing server | smtppro.zoho.com 465 SSL or 587 STARTTLS |
| Host by data center | Swap .com for .eu, .in, .com.au or .jp |
| Password | Zoho password, plus app password with two-factor |
| Access toggle | Enable IMAP or POP in webmail first |
| Username | Full you@yourdomain.com address |
Troubleshooting Zoho Workplace Mail Connections#
Find the exact error your email app shows, then apply the fix:
| Error you see | What it means | Fix |
|---|---|---|
| Authentication failed on a paid account | Personal host used for a Workplace mailbox | Point the client at the pro hosts, imappro.zoho.com and smtppro.zoho.com. |
| Credentials rejected though correct | Wrong data center suffix | Match the host to your region, such as imappro.zoho.eu on the EU data center. |
| Cannot connect to server | Wrong port or encryption | Confirm IMAP or POP is switched on in webmail. Then verify 993 SSL and 465 SSL. A firewall or VPN can block these too. |
| Password keeps being asked | Two-factor is on so the plain password fails | Generate an app password at accounts.zoho.com and use that. |
| Messages stuck in Outbox | SMTP authentication is off | Enable outgoing server requires authentication and give it the incoming login. |
Reader Reported Fixes
A paid mailbox refused every password until the host changed. The client was pointed at imap.zoho.com, the personal host. A Workplace account on a custom domain needs imappro.zoho.com. Switching the incoming and outgoing hosts to the pro ones let it connect at once.
An EU based account kept failing on the US hosts. The organization was created on Zoho's EU data center, so the correct hosts end in .eu. Changing imappro.zoho.com to imappro.zoho.eu and smtppro to match cleared the rejection.
Keeping a Copy of Your Zoho Mail#
A backup uses the same pro host login. The IMAP host imappro.zoho.com on 993 SSL for your data center, your full address, then your password or an app password. That is the same credential a mail client signs in with.
A business mailbox is worth a local copy. Staff changes, plan changes and domain moves all put mail at risk. An offline archive keeps it whatever happens to the account.
Closing or moving the account? Back up first, then move on. Once a mailbox is deleted, recovery is rarely on offer.
Taking your mail to a new account? The Univik Email Migration Tool copies every folder from the old account to the new one. Enter the IMAP settings from this page for the Zoho Workplace Mail side and your new provider's settings for the other.
Rather not do it yourself? Our Email Migration Services team plans and runs the whole transfer for you and verifies every folder arrived.
Use These Settings in Univik Email Backup#
The same IMAP settings above let you download your complete Zoho Workplace mailbox to your computer. Univik Email Backup saves everything as PST, MBOX, EML or PDF files you keep forever, even if the account closes.
- Download Univik Email Backup and install it on Windows.
- Select Zoho from the source list. If it is not listed by name, choose IMAP.
- Sign in with your full address and your Zoho password. Use an app password if two-factor is on.
- Should the tool want server details, give
imappro.zoho.comon port993over SSL, matched to your data center, from the IMAP table above. - Pick a saving format and folder, then start the backup. Large mailboxes download in the background.
Univik Tools That Use These Settings#

Email Settings Glossary#
IMAP
Internet Message Access Protocol. Reads mail that stays on the server, so all your devices see the same inbox, folders and read status.
POP3
Post Office Protocol version 3. Downloads mail to 1 device and can remove it from the server. Older method, still useful for local archives.
SMTP
Simple Mail Transfer Protocol. Sends your outgoing mail. Every account needs it next to IMAP or POP3, which only receive.
SSL / TLS / STARTTLS
Encryption for the connection. SSL/TLS encrypts from the start (ports 993, 995, 465). STARTTLS upgrades a plain connection (port 587).
App Password
A 16 character code that replaces your real password inside email apps. Safer because you can revoke 1 app without changing your main password.
OAuth
A one-off password for a single app, generated when two-factor is on. It replaces your normal password in that client only.
How We Verify These Settings#
Since 2013 Univik has made email backup, migration and converter software. These tools log into the Zoho pro servers over IMAP and SMTP every day, so any shift in a host, port or sign in rule appears in our own logs early.
Every value on this page is confirmed with 3 checks: a live IMAP and SMTP connection from Univik Email Backup, a comparison against Zoho's own help, which documents the pro hosts, the data center suffixes and the app password rule. A provider notice prompts a recheck. We look again each quarter regardless.

Frequently Asked Questions
Use imappro.zoho.com on port 993 with SSL and your full you@yourdomain.com address. Swap the .com suffix for your data center. With two-factor on, use an app password. The full table is under IMAP settings.
Two things reject a correct password on Zoho. The first is the host. A Workplace mailbox needs the pro hosts, not imap.zoho.com. The second is the data center. An EU account uses the .eu hosts. Fix those, then use an app password if two-factor is on.
IMAP suits most people, holding phone, computer and webmail on a single shared inbox. POP suits a lone machine wanting a local download, though new Free plan accounts do not get POP. The comparison lays it out.
Yes. The pro hosts, ports and SSL are identical on every device, once the suffix matches your data center. Only the menu labels change from app to app. The client setup guides walk each one.
Only when two-factor authentication is on. With it off, your normal Zoho password works in a client. With it on, a client cannot answer the second step, so you generate an app password at accounts.zoho.com and use that instead.
Yes. Use the SSL ports on this page with your password or an app password. The link is then protected. Look over the connected apps in your Zoho account security now and then, dropping any you no longer use.
An IMAP client gathers mail as it syncs, but a purpose built backup tool runs faster and writes portable files you open anywhere. See how to back up your Zoho mailbox. Have exports in some other format already? An email converter rewrites them into PST, PDF or whatever your next app expects.
On Zoho the common trigger is a change to two-factor that then demands an app password. Another is a client still pointed at the personal host. Check what changed recently. A fresh app password or the pro host usually settles it.
An email migration tool transfers mail straight from one account to the other across IMAP. You need the Zoho pro IMAP settings with a password or app password for this side, plus the destination details. Every folder and date stays intact.
If setting this up feels risky or you have many accounts to move, our managed email migration service does the entire job for you.
