Outlook 2011 for mac can not rebuild microsoft database

I have an identity that has grown to 45Gb and it can not be rebuilt.
It seems to work, but we created a new identity to make it smaller
We have not been able to rebuild it. This always fails.

I need a couple of the folders out of this identity.
The export of a folder fails with a "Outlook has experienced a problem" and stops.

How can we rebuild the MS Outlook Identity?

Did you follow these steps to rebuild database "Rebuild the Outlook for Mac 2011 database to resolve problems"

Plus via this link "Basics for a Successful Rebuild"
No folder should have over 2GB of data. Generally the Inbox and Sent folders are the folders with too much data. Be sure they are under the 2GB limit. Generally this is less than 10,000 messages but with large attachments could be less. Make subfolders e.g. Inbox 2011, Inbox 2010, Sent 2011, Sent 2010 etc to help reduce the number of messages in a folder.

Make sure you have enough available space, "Outlook rebuild results in folders named Recovered"
Many users will think that the amount of free space required is excessive. Like Entourage recovery, it does take enormous amounts of free space. The size of the Identity, the amount of corruption, fragmentation on drive, RAM are all factors that will determine how much space is required to rebuild.

I saw these links before putting my post up.
They were not the solution.

I finally found the solution with a Microsoft Level 2 tech.

THE SOLUTION:
We have 5 email accounts Outlook was pulling from. 1 Exchange, 2 IMAP, 2 POP.
After deleting all the extra folders and virtually everything else I could, the Identity size only fell from 45 Mb to 44 Mb.
The solution was to delete the Exchange and IMAP accounts and that released the space in the Identity which quickly fell to 8Gb.
Exporting folders and the rebuild of the Identity both worked then.

The overall size of the Main Identity should be @ 20-25 Gb. At a size smaller than this, Outlook 2011 will shrink the size of the Identity dynamically based on the email, folders, etc. that are in it. Deleting items will cause the Identity size to shrink.
Above a certain point, perhaps 22-30 Gb, this will not happen and the accounts holding the Exchange and IMAP email must be deleted to release the space.

While we created a new identity as part of the process, I do not know if that was necessary. It was the deleting of the Exchange and IMAP accounts that did the trick.
