One of our users is logged out of his Outlook on a weekly basis. Everything works fine on Friday, but when we come back after the weekend, he's been logged out of his email and his credentials need to be reentered before he can send/receive anything. We have the same setup for dozens of other users, but none of them have this issue. What can cause this, and how can we fix it?
