Managing a Multi-Mailbox Search in Exchange Server 2010.

First and foremost, I have have to acknowledge (and thank!!) Anderson Patricio of MSExchange.org for the information that he provide that help me deal with a very difficult situation.

I have just started working with our Exchange server and GSuite Administrator functions. Administration came to me and asked if I could search all of our Exchange mailboxes for a certain search term (name) in which they have been asked to provide documentation about.  I had an idea that it could be done but I had no idea how or where to start.  Patricio's article on Managing a Multi-Mailbox Search in Exchange Server 2010 explains it all.  Be warned though...it has seven sections to it.  There were some instances where I was caught mumbling "What?!?" but I was able pull it off.  

After successfully performing a Multi-Mailbox Search in Exchange and being able to view the results, the next question I was asked was "how can I save it in a file format?"  When I first did the search I forwarded the results (emails) but the organization I was working with said that by forwarding them it misidentified the original senders/receivers.   

Being in the OWA (Outlook Wed App), there was no menu to "File, Save As", so I had to use an installed version of Outlook (on a PC not a Mac).  I setup the account that had the rights to the search results in Outlook, launched it and voila...NOTHING!! I saw my mailboxes but not of the folders that contained my search results.  I googled "how to view my Discovery Search Mailboxes" and found this: "Use Outlook to Open a Discovery Mailbox".  

I used the following instructions and voila, I saw everything, now I could export them as a file and was exactly what I looking for.

Open the discovery mailbox from your Outlook profile

To display the contents of the discovery mailbox in the folders list in the Navigation pane when you're connected to your cloud-based mailbox with Outlook:

1. In Control Panel, click Mail, and then in the Mail Setup - Outlook window, click E-mail Accounts.
   Not seeing Mail? Mail appears in different Control Panel locations depending on the version of the Windows operating system, the view of Control Panel selected, and whether a 32- or 64-bit operating system or version of Outlook 2010 is installed. The easiest way to locate Mail is to open Control Panel, and then in the Search box at the top of window, type Mail. In Control Panel for Windows XP, type Mail in the Address box.
2. On the Account Settings page, on the E-mail tab, select your account, and then click Change.
3. On the Server Settings page, click More Settings.
4. On the Microsoft Exchange page, click the Advanced tab, and then click Add.
5. On the Add Mailbox page, type Discovery Search Mailbox and then click OK.
6. Click Apply, and then click OK.
7. On the Server Settings page, click Next, and then click Finish.
8. On the Account Settings page, click Close, and then close the Mail Setup - Outlook window.
9. Start Outlook and in the Navigation pane, click Discovery Search Mailbox.

In a nutshell you have to give an account Admin rights in Discovery Management to perform the query, once done Exchange sends the results (the emails) to a designated mailbox.  I could try to explain it better, but I'm sure I would only make things worse.

So for those needing a global search of your Outlook mailboxes, Mr. Patricio has obliged us. It may not rocket science, but I think it is a close second.
