I have an Exchange 2010, 2 Domain Controllers, Behind a TMG Forefront. several XP and 7, mac and Ipad as clients,
My problem is that very often the Outllok 2007 ask for credentials, then we give it, but Outlook doesn't cacht it and ask again, We have to close Outlook and start again, and the yes it put online.
The mac and Ipad usually ask credentials.
I think the problem is in the Exchange or the relation between Exchange and the Domain.
Where or How can I review it?
