MS Outlook is a widely preferred and trusted email client that is being used today by almost every corporation and many individuals. Just like every email client, it has a few bugs which need to be fixed. These bugs lead to error codes; one such notorious error code is 0X80072f06. This error code is linked to the OST file. This happens when Outlook is unable to sync with the Exchange server. Outlook desktop client stores the user information such as names, email address, etc. in an Offline Address Book (OAB) which is similar to Global Address List (GAL) of Exchange server.
However, with Offline Address Book (OAB), Outlook users may face the error 0X80072f06 in some situations.
This issue is more common among the users who have recently migrated to a different version of Exchange server. Due to this, users are unable to download the OAB. OAB is available on the server but is not found by Outlook.
Some of the prominent reasons behind this error are listed below:
A possible workaround this error would be to delete the existing OAB file and to download a new one. Afterward, one should synchronize the new file with the server, hence fixing this issue.
Restoring the system to an earlier time may help you resolve this error. To restore your system to the previous point, follow the step outlined below:
It will take a few minutes for the Windows to restore the system. After resetting the system, check if the issue is resolved or not.
The error can occur due to improper synchronization of the OAB file with Exchange Server. So, deleting or updating the existing OAB file might solve our problem.
One can force an update (manually) the OAB as described in the steps mentioned below:
One can also disable the option Download changes since last Send/Receive just to make sure that you get a completely fresh copy of the address book, but this could take a little longer.
A second way to make sure that you get a fresh copy of the OAB file is by renaming the OAB files with .old extension at the end of the name.
Note-For Windows Vista, Windows 7, Windows 8 and Windows 10
Note: If you are using Outlook 2007 or earlier versions then you might have to rename the individual OAB files. There are six OBA files:
After deleting these files, a manual update is triggered within the Outlook.
