Migration from Microsoft Exchange server

The Exchange Migration Wizard can be used to migrate Emails directly from an In-house Exchange Server or from a Hosted Exchange environment. If you have already installed the Wizard, you can directly follow the instructions to migrate the data from the Exchange server and skip up to the Installation process.

Ensure that you have administrator rights on the client machine, to install and run the wizard. Also, check that the email accounts, to which the emails have to be migrated, have been created in Zoho Mail and are accessible by the users. In case you want to begin user provisioning from the Exchange Environment, choose the User Migration option in the Wizard and follow the instructions there.

Zoho Mail now supports migration from Exchange Server through the web. The migration options for Exchange servers are provided on the Zoho Mail UI. Migration through the web does not necessitate downloading the Migration Wizard. For more information, refer this help page.

If your Exchange server has online access, we highly recommend that you migrate using the web option, as it is much faster, and you will have better control over the migration.
