We have an AVD setup with a few VMs for our CC agents. Up until a few months ago everything was runnign smoothly, then we started to get a storm of authentication errors bearing the code 1001.
We have tried every online fix we could find. For example lots of reports regarding the oneauth folder deletion and all that it entails.
We have tried replicating the error but to no avail, bevause it keeps coming up at random! There's no common denominator in any of the incidents we encounter. It affects different users, using different machines at all times of day. It doesn't matter if the VM the user's on is full or if there's only one person on it.
It's all random and we 've ran out of ideas.
As this affects the client login for Teams and Outlook, we have instructed our colleagues to simply go to the web version of those apps, but the problem is that their business flow involves opening .msg and .eml files. It is also important for our users to be able to access a saved email's attachments. But this does not work if they get the 1001 error.
Has any brave soul here stumbled upon a life-saving article that maybe I was unable to find? Is there a solution to this problem or do we have to wait for Microsoft to issue an update?
