6.8. What to Do When Outlook Will Not Open an Attachment


Problem:  Outlook has reached its limit for saving copies of a temporary files of the same name.

The error message that is displayed is: Can't Create file: filename.xxx. Right-Click the folder you want to create the file in, and then click properties on the shortcut menu to check your permissions for the folder

 

Why this is happening:

When Outlook opens an attachment, it saves it to a temporary folder.  When it opens an attachment that has the same name as a file that is already in that temp folder, it incrementally appends a number to the name. Once it reaches (99), Outlook will no longer open attachments of that name.

 

Solution:  To find these files and delete them.

Here is the website that has the instructions that helped me figure out where your files were.

The key is to go into the registry and find the temp filepath, which is listed at the following key:

HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security, under the key OutlookSecureTempFolder

COPY AND PASTE THAT FILENAME INTO WINDOWS EXPLORER. If you try to navigate to that path it will be hidden and you will not see it listed.

 

An example path would be:

C:\Documents and Settings\nmoore2\Local Settings\Temporary Internet Files\OLK4

 

Once you delete the files, you will be able to open these files again.
