cdn.office.net is fully, unrestrictedly accessible. Also, I believe those re-authentications are actually ALL the app is doing in those moments. It's not actually loading anything, not emojis, not notifications or anything else (all of the app still works normally) - it's just re-authenticating, re-authenticating, re-authenticating, re-authenticating... in the background (eating quite a bit of CPU and bandwidth in the process).
