ADFS3 rollout has been pretty disastrous so far - lots of errors which neither ourselves nor Microsoft can resolve.
Hoping someone can help on the latest issue though:
When we try to edit documents in Office365 using "Edit in Powerpoint") we get an additional login screen(s) which we can't get past. Editing in e.g. PowerpointOnline works fine though. Same for Word, Excel etc.
Pop-up errors are:
"Call us overprotective but we need to verify your account again before opening the document"
When trying to login, we get
"We are unable to connect right now. Please check your network and try again later."
or sometimes something along the lines of "your account is already signed in to this document"
Tried testing with different windows profiles, running klist purge, rebuilding the farm - unable to determine what is causing it though.
This issue only occurs on ADFS3. When we rollback to ADFS2.1, this error goes away after waiting 30-60 minutes (I'm really curious about what is changing in this time frame).
Most users are affected, but some are fine. Sometimes the issue goes away for a user for no apparent reason. Microsoft already confirmed the setup of ADFS seems to be fine.
Anyone else had this? We had this issue previously and it turned out to be certificates, but the certificate seems to be fine and is the same one as we use on the old ADFS farm.
