IMAPOAuth2, The refresh token could be expired or invalid

Post by TechnikOnkel »

I am using Office365 as SMTP Sender.

The connection worked without any problems after setup. After half an hour the following error message appears. If I then save the SMTP data again and confirm the OAuth connection with Office365, it works again for about 30 minutes. Then the error message comes again.

IMAPOAuth2: Could not request access token for xyz@domain.com/outlook.office365.com'. The refresh token could be expired or invalid.
