I am trying to open an additional mailboxes from outlook 2010 but the button "Add" in the account settings is greyed.
2 exchange account
1.private exchange server 2010
2.corporate exchange server 2003 (mailbox of another user I want to add is there)
Both servers work correctly on Outlook 2007 (primary mailboxes and additional mailboxes), but for what reason Outlook 2010 greyed the add button ? because of the 2 exchange account ?
Thanks for your help
