Hi we recently upgraded our Exchange Server to 2013.
Since then users on Outlook 2010 and Outlook 2007 are receiving the following message when trying to open an word or excel attachment:
Cannot open file: C:\\users\dianaw\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content....The file may not exist, you may not have permission to open it, or it may be open in another program. Right-click the folder that contains the file, and then click Properties to check your permissions for the folder.
The attachment will eventually open after several tries.
I have tried the following:
I have checked the permissions on the C:\\users\dianaw\AppData\Local\Microsoft\Windows folder
I have looked at cleaning out the Temporary Outlook Files folder
I have modified trusted locations in word and excel to allow sub folders.
I have tried to open outlook in safe mode in case it was an add-in that was causing the problem.
Any suggestions as users are getting frustrated.
