I keep getting this message "Cannot open this item. Outlook cannot perform this action on this type of attachment" when trying to open or delete a task. Outlook 2010 using Exchange 2010. Only having problems with one user. I already done the following
• Uninstall/Reinstalled Office 2010
• Updated Workstation with Microsoft Updates
• Rebuilt the .ost file
• Ran in safe mode, checked for errors
• Opened the mailbox on another machine and the same problem persists
I'm able to open the task in OWA but not in Outlook. Anybody have any ideas that i can try ?
