Hi, i got problem connecting Outlook 2013 to a Exchange 2007 account. I only have this problem on one user, if i make a new profile that point to a different user on the same machine/outlook then i can open that users mailbox, but on one user i get the error that say "Cannot start Microsoft Office Outlook. Cannot open the Outlook window" If i use a machine with outlook 2003 i can connect without problem. I have tried 3 different machine with Outlook 2013 and none of them can connect to that users mailbox. I have tried resetnavpane etc but the problem must be on the Exchange server since its only one user and only with Outlook 2013. Many other users with outlook 2013 dont have this problem to that server.
