Zoho Mail User Guide

Email Migration

Zoho Mail Suite provides you various options to migrate your email from your current provider/ format to Zoho Mail. In case you have the email data of the users to be migrated in your Mail Server, which supports connection via POP or IMAP, you can do an IMAP or POP Migration for all the users of your Organization from Zoho Mail Admin console itself.
In case you have the data in Exchange Server or in the form of PST files, we have an inhouse utility, available on request using which you can perform a direct migration from Exchange Server, or migrate just the PST or EML files to the respective Zoho accounts. The process to Migrate from Exchange environment is explained in this help page.

POP or IMAP Migration

You can perform a Server to Server migration to migrate your emails from your previous provider to Zoho. Zoho Mail Migration Tool in the Control Panel supports both POP and IMAP Migration from your other email server. The Administrator can initiate a migration from the source accounts to the accounts created in Zoho Mail.
IMAP Migration retains the folder structure the user has in the previous email server, whereas, POP Migration fetches all the emails to the Inbox folder. The Administrator needs to have the following information before hand to initiate a migration.

  • Name of the Server
  • Server Port
  • SSL Type
  • Source User Names and Passwords

The Administrator can optionally specify the maximum concurrent connections allowed to the server, any folders he wants to exclude for users during migration (like Spam, Junk mail etc.), the times at which the migration should not be carried out etc.
