Office365 account disconnects (only the account that needs two-factor authentication)

[hkorsvoll (Håvard Korsvoll)]

I believe the reason for the token lifetime to only be 24 hours is that the Mailspring application is registered as a Single Page Application at Microsoft. Look at this post under the other thread:

Institutional Office365 not working

Hi all I have done some more investigation. Looking through Microsofts OAuth 2.0 authentication protocol, I found this section: Microsoft identity platform and OAuth 2.0 authorization code flow - Microsoft identity platform | Microsoft Docs The following text describes the behaviour we experience in Mailspring. Maybe it is worth digging into this @bengotow. [bilde]
