We are receiving messages about Exchange connectivity in OCS client - red exclamation point in OCS client warning of connectivity to Exchange. Connectivity warning frequently in VDI but occasionally on physical machines. Slow loading or no GAL available for some OCS clients.
We've also noticed this only occurs with users who have Exchange 2010 mailboxes. Also, the "red exclamation point" error only presents itself when Outlook is closed.
Can someone offer some advice?
