Best Methods to Fix Outlook Error 0X80072f06

MS Outlook allows the user to access the mailbox with all the emails without any latency with a constant connection with the email server. Ideally, there are no errors while accessing the mailbox, but sometimes it shows an error while synchronizing the account with the server. One such common error is 0X80072f06 which affects the Outlook account connected with Exchange Server. You may be aware of the Global Address List (GAL) of the Exchange Server. Offline Address Book is its offline counterpart that saves email address, user name, etc.

Actually, the OAB is the snapshot of Active Directory server information that is present in the global address list. OAB does not contain some additional information like custom properties of the active directory, organization hierarchy information, and group membership information. Outlook requires cached mode enabled to keep the connection between OAL and the global address list from Active Directory. If the connection is broken, then it will show the error.

The 0X80072f06 error can occur when OAB loses synchronization with Exchange Server.
