Yesterday morning most of my windows users were repeatedly being asked for their passwords when opening Outlook. Despite using the correct password they still could not get in.
The only workaround I have found is to reset their domain passwords & reboot the PC, sometimes more than once. This is not happening to all users.
We are on Exchange 2003 SP2 on a 2003 SP2 server.
The clients are Outlook 2003 & 2007 on XP & Vista. When this happens they are also unable to log into OWA. However, I can log into their OWA from my PC (Windows 7).
I also have 2 Entourage 2008 users who are getting a Error - 18599
