I'm managing an Exchange 2007 Server installed on Windows Small Business 2008. Recenlty I installed the server and updates available. Since then, have alot of problem with the server.
I had to manually delete every IIS SBS Web Application and recreate it with the Exchange Management Shell.
The problem I have now is the following:
When user use Outlook they enter their credentials and after a couple of seconds another popup appear that demand to enter credentials again. Even if I enter the correct user and passwords, this popup always appear a couple of seconds later.
It's my understanding that this problem is releated to to EWS entry in IIS, but cannot find the necessary solution to solve it.
It's important to note that user can still access email, calendar, note etc. even if they have this popup. Once we close the window a couple of times, user can use outlook normally until the problem appear again.
