Outlook OAB Download Error 0x80200051

Sometimes you have the need to download the Offline Addressbook (OAB) for the Outlook email client manually.

When initiating a manual OAB download you might encounter a 0x80200051 error. A common mitigation scenario is to switch between Outlook Online-Mode and Outlook Cached-Mode multiple times. This mitigation scenario does not solve the issue.

OAB Download Error Message (DE)

When you active Outlook Cached-Mode it is required to perform a full OAB download. The OAB download dialogue provides an option to download OAB changes only. This option ist selected by default. To start a full OAB download you must deselect the checkbox.

OAB Download Settings (DE)

Using this download setting you will not encounter the mentioned error and the Offline Addressbook is downloaded by your Outlook email client sucessfully.

Enjoy Outlook!
