We have received the below alert where Microsoft Exchange System Objects “HomeMTA” attribute is set to deleted object container.

 Process w3wp.exe () (PID=6696). Object [CN=SystemMailbox{50208E3D-2500-4040-9784-FDAEFC473EB3},CN=Microsoft Exchange System Objects,DC=ccu,DC=clearchannel,DC=com]. Property [HomeMTA] is set to value [ Objects/Microsoft MTA
DEL:eea9bd65-1f5a-4ca0-baca-5534d2d97ac2], it is pointing to the Deleted Objects container in Active Directory. This property should be fixed as soon as possible.

We have checked and found that there are two system mailboxes currently being in use. PFB the screenshot for your reference.

There are other two system mailboxes as well.

1)      SystemMailbox{1f05a927-3ecf-414d-97a8-cd794d4dd341}
2)      SystemMailbox{50208E3D-2500-4040-9784-FDAEFC473EB3}

The first in list have following attributes set to null, therefore it seems we can simply set the homeMTA attribute of the second mailbox (problematic) to null as it is not in use.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try running:

ps> get-mailboxdatabase |  Get-Mailbox -Arbitration | Update-Recipient

Or also you can use ADSIedit to set HomeMTA/MDB attrib:
