Error opening attachments / Cleaning out the Temporary Outlook Files folder
opening an attachment directly from within Outlook you could get an
error message saying that it can’t create the file and to that you need
check the permissions on the folder you want to save it in. In most
cases the permissions on the folder isn’t the issue but the fact that
the folder is “full”. When you open an attachment directly from within
Outlook it will first save a copy to a subfolder of the Temporary
Internet Files folder. Cleaning out the folder will solve the issue.
Outlook Secure Temp folder
this is easier said than done. The subfolder name Outlook creates (on
installation of Outlook) in the Temporary Internet Files folder is quite
random. In Outlook 2003 and previous, the name starts with OLK and is
followed by up to 4 random numbers or letters. In Outlook 2007 and
Outlook 2010, this folder is called Content.Outlook and then has a
subfolder which is named with with 8 random numbers and letters. In
addition, by default, you cannot simply browse to the folder to clean it
out. Getting to the Temporary Outlook Folder can still be accomplished
in 2 easy steps though.
