This post is a follow-up to my issues with Znuny, which has not been functioning since this post:
viewtopic.php?t=44351
I contacted Microsoft support, who were able to resolve the connection issue with Oauth2, so now the token is successfully renewed.
However, the problem now is that znuny cannot read the email inbox reserved for it.
I therefore have two alerts in the logs:

* OK The Microsoft Exchange IMAP4 service is ready. [Rg.......A==]Microsoft had me change the Oauth2 API permissions as follows:
And that's all the help they can give me, so they asked me to contact Znuny support for further assistance.
That's where I am today.
Can anyone help me, because I really don't know what to do anymore.
Thank you in advance.
