Email migration
Migrate email from Outlook and Microsoft 365
Outlook.com, Hotmail, Live and Microsoft 365 no longer accept passwords for IMAP access. With Migrabox you sign in with your Microsoft account and we copy all your mail to the new mailbox, including when Outlook is the destination.

You don’t have to type these in — we work them out from your email address. They’re here for transparency, or in case your provider uses different values.

Good to know before you start
Since September 2024 Microsoft only allows IMAP access to Outlook.com and Hotmail mailboxes through Microsoft account sign-in (OAuth); for business Microsoft 365 it has been the case for longer. App passwords no longer help.
On Migrabox, press Sign in with Microsoft and allow access to your mail: you never give us a password. It’s included in paid plans; we revoke access and delete the tokens 14 days after the migration ends.
At work you may need an administrator’s approval or IMAP turned on for the mailbox: if so, we tell you before you pay, with a link to send to your administrator.
How it works
Enter your Outlook address and password: we recognise the server and count your emails.
Tell us your new mailbox: we check we can sign in before asking for any payment.
Pay once and watch the copy live. Your Outlook mailbox stays exactly as it is.
Frequently asked questions
Can I use an app password with Outlook?
No: Microsoft turned them off for IMAP access. You sign in with your Microsoft account, using the button in the wizard.
What if Outlook is my destination?
It works the same way: sign in with your Microsoft account for the new mailbox too, and we copy your email there.
