ISSUE
When opening an attachment directly from Outlook you would see an error about unable to create the file and 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 sub folder of the Temporary Internet Files folder hence throwing the error.
** NOTE THE BELOW INVOLVES USING THE REGISTRY EDITOR**
If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. See the articlehttp://support.microsoft.com/kb/322756 to backup the registry on your machine or ask one of your IT team members to perform the following tasks
In the registry Editor and then getting to the folder Locating the folder 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:
In Outlook 2010 and 2013, this folder is called Content. Outlook and then has a subfolder which is named with 8 random numbers and letters.
Unfortunately this is easier said than done. The subfolder name Outlook creates (on installation of Outlook) in the Temporary Internet Files folder is quite random.
Next we have to find the location of this temporary folder.
| Outlook version | Registry key |
|---|---|
Outlook 2010 | HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security |
Outlook 2013 | HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Security |
Outlook 2016 | HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Security |
To this, open the Registry Editor using the Windows Key + R key combination to open the Run Command window and type in REGEDIT or you can also type in REGEDIT in the Search box (Start | Search box)
