We use a pop server hosted email for our email. Everyone is on outlook. Yesterday many users had the dialog box come up for them to enter their password. They would click ok about 10 times when it popped up and it would work. This would be fine for about 3 hours and then the same thing happened. I talked to our email host provider and they said it was a micrsoft update. Any ideas on if this is true and any options on what I can do to remedy this?
