The segment name is a random alphanumeric string that means nothing to us, and changes each time an error is logged.
For one user, I noticed that their Office licence location was a different country to the rest of us. I changed it to match the rest of us, and that made the error go away. However, another user is getting the error even with the correct country.
Can anyone tell me the root cause of this error?
UPDATE
User A was getting the error all morning, but is now working fine. Nothing has changed.
User B is still not working.
My user has worked all along.
