Migrate Yandex to Office 365: Setup, Free and Expert Ways
Written by Justin Cener, Technical Executive and Staff Writer at Corbett Software. Justin covers email data formats and migration workflows.
Moving a Yandex mailbox over to Office 365 and want it done without losing a single folder? The migration itself is the easy part. What catches almost everyone is a two step setup on the Yandex side that has to happen before any method will connect at all. Get that right and the rest falls into place.
Summary: To migrate Yandex to Office 365, first enable IMAP in Yandex and create an app password, because Yandex turns IMAP off by default and rejects your normal password in outside apps. Then run a free IMAP migration from the Microsoft 365 admin center, or use the Corbett Email Migration Tool to move mail, contacts and folders together without admin setup.
Why Move from Yandex to Office 365?
The reasons tend to be practical rather than dramatic. Office 365 ties mail to the wider Microsoft set of Outlook, Teams, OneDrive and the Office apps, which is where a lot of workplaces already live. Its 1 TB of OneDrive storage dwarfs the free Yandex allowance, the shared calendars and contacts suit team use, and keeping mail with a global provider sidesteps the access worries some users have had with Yandex since 2022. Whatever your reason, the aim is to land the old mail in Office 365 with nothing dropped along the way.
The Setup Yandex Forces on You First
Skip this part and every method below fails on the first connection attempt. Yandex is stricter than most mail providers, and it needs two things switched on before any outside service can read your mailbox.
1. Turn on IMAP. Yandex has IMAP disabled by default. In Yandex Mail, open Settings, go to Email Clients and tick From the imap.yandex.com server via IMAP, then save. Until this is on, no client or migration tool can connect, whatever else you do.
2. Create an app password. Yandex also refuses your normal account password in outside apps. Open Security, then App passwords, choose the Mail type, name it and generate the password. You will use that generated password, not your usual one, in every method below.
- IMAP enabled under Email Clients.
- App password created under Security.
- The Yandex IMAP server is imap.yandex.com on port 993 with SSL.
With both done, your Yandex mailbox is finally reachable, and the rest of this guide works.
Free Method: Microsoft’s Built In IMAP Migration
If you administer the Office 365 tenant, Microsoft includes a free IMAP migration in the Exchange admin center, no third party tool required. Microsoft documents the full process in its guide to migrating IMAP mailboxes to Microsoft 365.
- In the Microsoft 365 admin center, make sure the destination user mailbox exists and is licensed.
- Open the Exchange admin center, go to Migration and add a migration endpoint of type IMAP, using imap.yandex.com as the server.
- Create a CSV file listing the Yandex address, the app password and the destination Office 365 mailbox.
- Add a migration batch, choose IMAP migration, upload the CSV and start it.
- Watch the batch status in the admin center until it reports the mail synced.
For an admin moving one or several users, this is a solid free route straight from Microsoft.
What the Free Migration Leaves Behind
Worth knowing before you rely on it. Microsoft’s IMAP migration moves mail only. Your contacts and calendar do not come across, you have to export and import those separately. It also needs tenant admin access, so it is closed to anyone who only has their own mailbox, and the CSV endpoint setup is sensible for an IT team but heavy for a single account. There are caps too, up to 500,000 items per mailbox and a 35 MB limit per message. For a simple mail only move by an admin, none of that bites. For a complete account with contacts, or a move without admin rights, it falls short.
Expert Method: Move Everything with One Tool
The Corbett Email Migration Tool closes those gaps. It connects to Yandex over IMAP with your address and app password, needs no admin console or CSV, and moves the mailbox to Office 365 with its folder structure kept intact. It carries across not just mail but contacts and attachments together, lets you filter by date, sender or folder for a selective move, and works whether you are an admin or just the mailbox owner. A free demo edition lets you evaluate the migration first, and it runs on all editions of Windows.

People Also Ask
Q2: What are the Yandex IMAP settings?
A2: The Yandex IMAP server is imap.yandex.com on port 993 with SSL, and you sign in with your full Yandex address and an app password. Insecure connections are not supported.
Q3: Can I migrate Yandex to Office 365 without being an admin?
A3: Not with Microsoft’s built in IMAP migration, which needs tenant admin access. A standalone migration tool connects with just the mailbox login and app password, so a regular user can run it.
Q4: Does Microsoft’s IMAP migration move contacts and calendar?
A4: No. It moves mail folders only. Contacts and calendar must be exported and imported separately, or you can use a tool that carries mail and contacts across together.
Q5: Will migrating delete my Yandex emails?
A5: No. Both routes copy the mail to Office 365 and leave the originals in Yandex. Your account stays intact until you close or delete it yourself.
Conclusion
The whole job hinges on the Yandex setup. Enable IMAP, create the app password, and the mailbox opens up to either method. From there an admin can run Microsoft’s free IMAP migration for a mail only move, while the Corbett Email Migration Tool brings mail, contacts and folders across in one pass without admin rights. Handle the two setup steps first and a migration that looks daunting turns routine. Are you moving a single mailbox or a whole tenant?
