MS Outlook Error 0x80072F06 is an error in the OST file. This happens when Outlook and Windows Live Mail is not synchronized with the Exchange server. In Outlook, each email client uses a list of contacts, such as the Offline Address Book (OAB). OAB is similar to GAL (Global Address List), which is located in the Exchange Server mailbox. The Exchange server contains the content of user information, such as names and email addresses, used by Outlook. Due to the presence of OAB, Outlook does not need to connect to the Exchange server every time the user sends the email.

You can work around this error by deleting the existing OAB file and downloading a new OAB file. If the new file is synchronized with the server, the error may not occur again. It is also recommended to ensure that the certificate name matches the server name of the client URL.
