Migrate email from Yandex 360 to Microsoft 365
Yandex 360 to Microsoft 365 combines the requirements of both providers: Yandex needs app passwords and IMAP enabled per user, Microsoft needs tenant admin consent for OAuth.

What breaks on this particular pair
- A Yandex 360 organisation admin can disable IMAP company-wide. Check before you start.
- Yandex 360 custom-domain logins are full addresses, unlike standard Yandex mailboxes.
- Microsoft 365 will not accept a password — OAuth 2.0 with tenant admin consent is required.
- Batch migrations are easier via CSV, one row per user.
FAQ
Common questions
Does every employee need their own app password?
Yes, if you use app passwords — each user creates one in their Yandex ID. For larger organisations OAuth on the Yandex side is the alternative.
