MOM Rule Name

Disabled user does not have a master account SID. Use Active Directory Users and Computers console to set an active account as this user's master account.

Explanation

This Warning event indicates an attempt to add a resource account to an access control list (ACL) failed because resource accounts do not have associated user accounts. For specific resources, see the events associated with this alert.

A disabled user does not have a master account security identifier (SID). (The attribute name is msExchMasterAccountSID.) This can occur for several reasons, including but not limited to:

  • The master account SID could have been deleted directly using the -LinkedMasterAccount parameter of the Set-Mailbox cmdlet in the Exchange Management Shell.

  • The account may have been created incorrectly initially.

  • The account may have been partially deleted, with its mailbox rights removed, but still retaining HomeMDB and other attributes.

User Action

To resolve this warning, do one of the following:

  • To keep and repair the account, do either of the following:

    • Use the Active Directory directory service Microsoft Management Console (MMC) to try and enable the account.

    • Use the -LinkedMasterAccount parameter of the Set-Mailbox cmdlet in the Exchange Management Shell to assign another account with mailbox rights as the external associated account for the problem account. This could be simply the Self account for the damaged account.

  • To discard the damaged account, either completely delete the account or at least remove the HomeMDB attribute for it. (Removing the HomeMDB attribute will make the account invisible to Exchange).
