What command you fire to get you that result ?
Normally the following accounts would have full permisions on the mailbox :
NT Auth\self
NT Auth\System
Domain\Exchange Servers
Domain\Exchange Services
Domain\Exchange Trusted Subsystems

But NOT the user himself.

in ADUC console, when i check user - Security - Advance settings - owner - it shows the Exchange server name instead of the user who created the user. See the attached.

Why it changed to the name of the exchange server.

In the topic you talk about a mailbox, now you say an user... not the same thing.

Might be a migration that happen sometime ?
Else someone had manually changed the ownership of the user.

The user is associated with Mailbox. It was created recently.  It was not done manually thats what I am sure.

Then maybe you can look in the log files / events and see who created the user and what permission has the person that created the user. But this is kinda hard if you do not have enabled auditing and also have the log files / events saved.
Without this is pretty hard to see who and when changed the ownership.
Try to look for event 4670 if you have auditing enabled.
