RH 2020 - having to keep signing in when using sharepoint for collaboration

I have set up a connection profile to a sharepoint directory and its all working fine. The only issue is that RH keeps asking us to sign back into Microsoft, despite selecting the stay logged in for 7 days check box. This seems to be happening whenever the session time out. Sometimes you can be logging in 7 - 8 times a day and it gets really tiring.

I have gone into the sign-in options and successfully logged into our domain.

Is there anything else I can do so that RH does not keep asking us to login all the time. We are worried about thinking we are signed into Microsoft and in fact we arent. How would this effect the checking in process? We dont want to lose files.
