I’m getting the above error when trying to open any kind of attachment in Outlook. I get the error when trying to insert file also. I have check the permissions on the temp directory. I have tried the following: deleting and recreating the network roaming profile, changing permissions on the mailbox, moving the deleted/sent items. This seems to work one day, but not the next. The person can go to another workstation and open the attachment without fail, but not from the workstation that they normally log into. Help please.
