When you try to open a file attachment in Microsoft Outlook, you get an error:
Cause :
This issue may occur when the Temporary Internet Files folder is stored on a server on which you do not have sufficient permissions.
Symptoms :
When you try to open or save an e-mail attachment, you may receive the following error message:
Cannot create file: file name. Right-click the folder you want to create the file in and click Properties on the shortcut menu to check your permissions for the folder.
Steps:
This problem occurs usually when Outlook cannot access the temp file the file is linked to. To resolve this problem, try the following steps.
1. Hold the Windows Key, then press “R” to bring up the Run dialog box.
2. Type “Regedit“, then press “Enter“.
3. Click “Edit” > “Find” and type “OutlookSecureTempFolder“.
4. When regedit has found the entry, it will tell you where your Outlook temporary files are stored. It will look similar to one of the following:
C:\Users\username\AppData\Local\Microsoft\Windows\INetCache\ Content.Outlook\randomnumber\
C:\Documents and Settings\username\Local Settings\Temporary Internet Files\OLKrandomnumber
5. Bring up the File Explorer, then navigate to the location in the registry key.
6. Delete all of the files in this folder.
7. Restart Microsoft Outlook and you should be able to open your attachment.
