Hello,
I've been unable to find an answer to this strange behaviour:
In our organization (Exchange 2010), the Outlook 2010 people pane only shows mail from internal users (using same exchange server) stored on PSTs, if some messages are stored on the Exchange mailbox (OST, as we use cached mode) those will not appear on the people pane mail tab.
However mail from external people (not sitting on our exchange server) will display properly in the mail tab of the people pane, regardless the messages are stored on PST or OST.
Any help will be greatly appreciated!
