Microsoft Outlook is a robust business email client widely used by organizations and enterprises running on-premises Exchange Server or Office 365. When you add an Exchange mailbox profile in Outlook, the profile is set up in Cached Exchange Mode by default. In addition, an Outlook data file (OST) is created, which stores a synchronized copy of mailbox items to provide offline access to your mail items even when the network is unavailable, or the server is offline for a seamless user experience.
Outlook also stores Online Address Books or OAB files on the local machine?a downloadable address list similar to Global Address List (GAL) available on the Exchange Server.
OAB files contain contact information, such as names, email addresses, phone numbers, etc., of all Outlook users? in the organization. It helps reduce the Exchange Server loads when an Outlook user searches for an address or runs an address query.
By default, the OAB files are automatically generated every 8-24 hours. However, users can also download the OAB file manually viathe File> Account Settings> Download Address Book option in Outlook 2010 and later versions to update the address list. In Outlook 2007 and earlier versions, go to Tools> Send/Receive> Download Address Book.
But sometimes, Outlook displays the ?Unknown Error 0x80072F06? when a user tries to download the OAB file manually.
The error message reads?Task abc@xyz.com reported error (0x80072f06):?Unknown Error 0x80072f06?
Some users have also reported error code 0x80190194 while downloading the OAB.

- Open Outlook and right-click on the email address
- Choose ?Open File Location.? Look for a file with .ost extension. You can enable extension via View and click the ?File name extensions? checkbox.
- Copy the OST file to another safe location and close the Outlook

- Restart Outlook. This will create a new OST file at the same location and possibly fix the Outlook Error Code 0x80072f06.
Try to download the OAB. If the error persists or the OST file is not recreated, your profile is possibly damaged or removed from the server. In such a case, the OST becomes orphaned and inaccessible.
