SSO issues in Word and Excel, but not Outlook
Hi, Strange issue started a month ago at a customer site. They use RDS with Office 365 installed. Historically this has been working fine, then it randomly stopped signing in properly for all use...
Hi,
I've tried most if not all of that already. Not about till next week to try anything else but in summary.
Have tried this with a brand new profile (nothing to clear from cred mgr etc). Same problems.
Have tried rolling back updates, again same deal (which surprised me, as I was sure it would be updates).
Copilot is not used in the estate.
There are no errors showing in the logs on the client / RDS / AD / Entra.
I have even tried running Fiddler and WireShark to see if I could find something being blocked, but nothing.
More testing will be done next week. Thanks for your reply.

We're experiencing the same issue. When starting word, there's no SSO experience, we get a login prompt. After which we get notices about usage. If we don't log on office isn't licensed. We also use shared computer licensing. If we log on, that's ok. I would grately appreciate it if you would keep me/us posted on your progress. I'll do the same, if I make any progress.
- No progress so far, though the customer has done some testing and it seems like the connected services within Word may not be signing in and that's what's throwing the prompt. More investigation needs doing, but I am not going to get chance till later in the week. But we are building a new server which only had Office on it, none of the other apps or policies, so we can rule a lot of things out quickly.
- Ok, I opened a support ticket at Microsoft premium support. I'll keep you updated about the result(s)bif any
- Hi,
I'm waiting for your update as well. I have the same problem, since the last update it is impossible to make SSO work on the applications (however works on the office portal from MS edge). The only thing I noticed is that the "autologon" Kerberos tickets no longer appear once the update is done. SSO does not work on outlook. I don't have any signs of error on my console, I don't even see a connection attempt.
