Office365 Token Expiration Issue


Office365 auth fails and requires re-auth daily, sometimes multiple times per day.

Here is the error message:

*** Mailspring Sync
*** An exception occurred during program execution:
*** {“debuginfo”:"Sign in to your account RETURNED {“error”:“invalid_grant”,“error_description”:“AADSTS700081: The refresh token has expired due to maximum lifetime.

To Reproduce…

Not sure - have an Office365 account?

Expected Behavior

Don’t keep making me re-authorize!




  • OS and Version: Ubuntu 20.04
    • Installation Method: not sure
  • Mailspring Version: 1.91-30

Additional Context

Did this ever get resolved? I’m seeing what seems to be the same error where MailSpring is reusing an old token that is no longer valid:

The refresh token was issued to a single page app (SPA), and therefore has a fixed, limited lifetime of 1.00:00:00, which cannot be extended. It is now expired and a new sign in request must be sent by the SPA to the sign in page. The token was issued on 2021-12-02T18:11:38.5127961+00:00.

Any advice on fixing this or working around (e.g. by manually deleting the token) would be appreciated!
