Recovering from an Outlook 2011 Crash, I found that this third solution worked for me, but it is rather time consuming and does not speak well for the trustworthiness of the program:
If Rebuild or Repair Fails, try these steps:
(Warning this could result in data loss. Create a backup first)
1. Create a new Identity then quit Outlook.
Find your Identity folder in the Finder:
Your User’s folder/Documents/Microsoft User Data/Office 2011 Identities/Main Identity/Data Records
2. The new Identity contains a Data Records folder.
3. Copy the Contacts, Events, Folders, Mail Accounts, Message Attachments, Message Sources, Messages, Note and Signatures folders into the new identity’s Data Records folder replacing the new folders from your Identity that will not rebuild or repair. NOT the root Data Records folder. Only the subfolders listed here.
4. When you open Outlook, select to rebuild the database
The Eclectic Rant 
Tried this with what little was left and it WORKED! Thanks.
I was able to copy my Mail and Exchange Accounts (and Prefs) and thank god for IMAP and Exchange, I only lost a few things.
Thanks for posting this.
I tried all the available steps including rebuilding and even downgraded and re-installed outlook but all in vain. At last I tried a paid solution http://www.outlookmacdatabaserecovery.com/ and recover all of the emails from identities folder of outlook.
Everyone facing outlook emails related issues should definitely give a try to this application.
Could be a paid endorsement. However, the program has a free demo. Worth a try for landlocked Outlook users.
