From time to time I would say every several weeks Exchange will prompt users to login?
I have two CAS one one CU3 one not
Two MBX Tranport Servers both on CU3
I plan to update the CAS not CU3 after April 15th as we are in busy season.
Any idea what could be causing this, MS tech is clue less and they find nothing in logs etc.
I end up rebooting both CAS and the issue goes away for several weeks but it hit again today.
just wanted to know if anyone had any idea what could be causing this??
