The Folder is Full Error

Last reviewed on December 30, 2013

Scenario: You receive this error message:

“Cannot delete this folder. Right-click the folder, and then click Properties to check your permissions for the folder. See the folder owner or your administrator to change your permissions. The folder is full”.

But the folder is empty; there are no permissions to change.

We believe this specific message is caused by an update but no one knows for sure. To delete the folder, you need to go into Safe mode.

It’s also reported that a corrupt view may cause this error. To fix, you need to reset the view on the folder. In Outlook 2007 and older, do this from the View, Current view menu. In Outlook 2010 look for Reset View on the View ribbon.

Finally, it may be caused by data file corruption. You can use scanpst on the data file to repair it. Repair a damaged Personal Folders PST file.

ANSI pst

If you receive “folder is full” error while using a data file created in an older version of Outlook it means that the data file is full and has reached it’s maximum file size. This is only an issue with data files created in Outlook 2002 and earlier. These files are limited to 1.9 GB for the data file, with up to 65,000 messages per folder.
