Switch from Microsoft 365 Business to Zoho Mail: step by step

How to move your mail, contacts and address from Microsoft 365 Business to Zoho Mail without losing anything. Most moves take an evening to set up, then a few weeks of forwarding.

Show me the stepsCompare them side by side

1. Before you start

   • Check where your address lives. Microsoft 365 Business runs on your own domain, like you@yourname.co.uk, so your address comes with you: you'll change a few DNS settings.
   • Check the space you need. See how much mail you have in Microsoft 365 Business, and compare it with Zoho Mail's plans (the cheapest is Mail Lite, $1 per user a month, yearly, with 5 GB).
   • Read the small print. Zoho Mail's page covers exporting, cancelling and refunds under "Before you sign up".

2. Open your Zoho Mail account

   Sign up on Zoho Mail's website (15 days free, and a free plan for small teams), and turn on two-step sign-in straight away. You'll find the link on Zoho Mail's page: Zoho Mail.

3. Bring your mail across

   Use Zoho Mail's importer. Zoho Mail's Import/Export settings bring in mail from another account over IMAP, or from .eml and .zip files. Zoho Mail's guide ↗

   Your old mail stays where it is while it's copied, so nothing is lost if you need to start again.

4. Move your contacts and calendar

   Export your contacts as a .vcf file and each calendar as an .ics file from Microsoft 365 Business, then import them into Zoho Mail. Most providers have both options in their contacts and calendar settings.

5. If you use your own domain

   Your address moves with you. Do this after your mail has been copied:

   1. Add your domain in Zoho Mail's settings, and create the same addresses there.
   2. A day before, lower the TTL on your domain's MX records (to 300 seconds, say), so the change takes effect quickly.
   3. Replace the MX records with Zoho Mail's, and swap Microsoft 365 Business's entry in your SPF record for Zoho Mail's.
   4. Add Zoho Mail's DKIM record, and keep your DMARC record.
   5. Check the result with a free DNS checker before you rely on it.

6. Check everything arrived

   • Compare the number of emails in each folder on both sides.
   • Send a test email to your new address from another account, and reply to it.
   • Check that mail forwarded from Microsoft 365 Business is arriving, and isn't going to spam.

7. Close Microsoft 365 Business, when you're ready

   Wait at least a month, until nothing new arrives there. On a free account you can leave it open with forwarding on instead. Before you close a paid account, download a last copy of your mail.
