Deleted AD User - Restored; Now Not Owner of Calendar Appointments

A user was accidentally deleted from active directory as he was a member of a test OU that was deleted via group policy management.

We restored this user, reapplied appropriate permissions, re-imported data from his .OST (so we lost no PIM data withing Outlook/Exchange), etc.

We ran into an issue where we had to delete all partnerships and syncs with devices he used, with the restored AD user account. My guess is that this account has a different SID-type attribute where it's considered a different user account as far as active directory is concerned.

Therefore the problem now is, that he's no longer considered the owner or originator of any meeting in his Calendar. Of course this user has potentially thousands of meetings setup for years... so it would be nice if we could somehow make him the owner.

I have a few ideas to make this work, but would like some input on this scenario. Any help is appreciated!

The restored object will always have the same primary SID in previous version till Windows Server 2003 with Service Pack 1.  RTM release of Windows Server 2003 does not preserve the sIDHistory attribute on restored user / Computer accounts.

After the User Object Is restored should be removed with Exchange attributes and run cleanup .

Unfortunately I am well past this point as the user has already been reanimated, but did not retain the SID. I created a new mailbox for him and reimported everything, hence him no longer being the owner of this calendar attributes.

Anything I can do now, with the situation as it is?
Think only way is to create the Calender Events again .  I Have not found anything more on this

I deleted the new mailbox and re-attached his old mailbox, and sorted everything out.
