Missing NT Authority\SELF on mailbox RRS feed

  • Question

  • Why would the NT Authority\SELF account disappear from one users mailbox. We are running Exchange 2007.

    Nothing that we know of changed for the user other than not being able to access their mailbox. Once we added NT Authority\SELF to the full access permissions everything worked.

  • When a user becomes a member of a protected group, not only does the user no longer inherit permissions from its parent object in AD, but some default ACLs are also removed and others added.

    So accounts added to protected groups have different ACLs than standard user accounts in AD. This can impact functionality, such as the ability to upload a user’s certificate to the Global Address List (GAL) in Exchange due to missing SELF permissions on the user’s AD account

  • I agree with that but the user was not added to any protected groups.

  • Someone likely removed it whether or not it was inadvertent. The only time I've heard of it being missing is during migrations.
