Unable to open Documents from SharePoint/OneDrive with Office 2013
MicrosoftObvious question perhaps since you mention that your Office version is too old for ADAL auth but could it be that modern auth has been switch on for the Office 365 tenant?
Is this happening for all users?

Well as far as I understand the documentation, modern authentication is always enabled by default on SharePoint but not on Exchange and Skype. So far we've never changed this.
Luckily it doesn't happen on all our installation. The only change on our side was a GPO for setting the trusted sites. Could a change in trusted sites result in credentials being revoked from the credential manager?
We now think that there are two issues playing, the first being stored credentials being revoked, the second issue not being redirected to our ADFS when presented with an authentication dialog through Word.
- BrjannBrekkanOnly way I can think of trusted sites change would be if this change meant that you moved the site in or out of being able to do SSO (using same as with the Intranet Zone). Could be other things in there as well as it is a more relaxed security setting.
The ADFS not being presented really sounds like you did move site that previously wasn't doing integrated auth to now trying to do that.
I would recommend installing Fiddler on the box and capture the traffic and perhaps even more importantly connect with our Support team to help you track this down as they know exacatly how to capture the traffic and do the analysis that might take you hours/days.
