DamianCastillo, absolutely.  We have no problems signing in.  The issue is that our users are signed out automatically every 7 days.  I have two cases open with Microsoft and no one can figure out what to change to prevent the sign outs.

Hello CosmoDenger 

 

Are you still having the same issue? usually, that kind of error can be found in the logs of the phones.

 

You can try checking this Poly community post:

https://community.polycom.com/t5/VoIP-SIP-Phones/FAQ-How-can-change-Logging-Levels-or-use-Syslog/td-p/4741

 

I would recommend you to enable these ones for exchange issues:

app1=2 , pps=2 , sip=debug, so=2 , auth=debug  nisvc= debug  pgui= debug  curl=1

 

and for registration issues:

app1=2 , pps=1 , sip=debug, so=2 , auth=debug  nisvc= debug  tls= debug  curl=1

 

Also, you may confirm that the consent its being applied by your O365 Admin:

That would give you an idea.
