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'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.

Similar here, where it all works fine in Edge and have reconfirmed the whole setup is correct. All good. Outlook does work on 2nd attempt. But Word / Excel / Etc. will never work, so my assumption is something in the Outlook logon / autodiscover process is getting that token and it works from there on restart.
I also see no errors, nothing being blocked and using things like fiddler, I see nothing trying to connect and failing. It's as if Word etc. has straight up given up even trying to do SSO. I assume MS have broke this in an update, because after weeks of testing, this is the only thing left that it can be!

- AdminSAPOct 11, 2024Copper ContributorHi,
someone find a solution ? Did the September update patch something ? - DivideByZeroJul 22, 2024Copper ContributorSorry for slow reply, still nothing to report back. Call with MS is currently "being investigated" and no feedback yet.
I, and the customer are both UK based. So also not EU member (any longer).
You could be on the right track, annoyingly we have a lot of American customers but we don't get involved with their O365 / Office stuff, so not sure I'll be able to test that theory. Shame, would be quite easy to test too.
1) New Wnidows profile
2) Ensure web SSO works via Edge etc.
3) Start Word - does it try and fail SSO?
But sadly, I don't have anyway to try that. - philippbeckJul 08, 2024Copper Contributor
DivideByZero May I ask where you are based (or rather the company)? I'm swiss and this exact issue is bugging several of our domestic customers right now. I thought that maybe something's off with swiss tenants as they're not an EU member and DMA legislation has not been implemented yet (AFAIK).
