Windows error codes can be cryptic and frustrating. Check out this Email guide for solving your Windows Error code 8072 and how to keep it from happening again.
This error code is seen when doing an email migration. It may be seen if you are present on the Exchange Server system as a user, or as a custom recipient. The error code may appear if you attempt to transfer GroupWise mail messages between directories.
Step-by-step instruction in case of Windows code 8072
This error code indicates that you are unable to transfer GroupWise mail messages from the Novell server to the Exchange Server 5.5 Service Pack 4, using the migration tool. It may be caused by an invalid registry entry, or a corrupt driver.
The first step to solving this problem is to delete any manually-created mailboxes, as well as the Windows NT account that is incorporated with it. In most cases, you will be able to solve the problem with a GroupWise update. It is more likely to occur if you are using an older version of GroupWise. Upgrade to GroupWise client 5.2 or better and then execute the email migration process, and it should execute without the error code presenting itself.
