I believe that I have a resolution although I am not particularly happy with it.
I was working on another bug that I had submitted to bugzilla and the engineer suggested do this:
firstname.lastname@example.org:~$ zmprov gmi email@example.com
firstname.lastname@example.org:~$ zmblobchk --mailboxes 10 --missing-blob-delete-item --verbose --no-export start Checking mailbox 10.
That action resulted in the removal of 25,005 NO_SUCH_BLOBS. Kinda scary. I don't know all what is lost now.
The good news is that resolved my Outlook massive ZDB problem. I can now sync folders like a normal person.
It is working quite nicely now.
