In this blog, I will let you know how to have your Exchange Online mailboxes searched from SharePoint Online. ( The steps apply to Exchange 2013 on-premise and SharePoint 2013 on-premise).

1. Create a E-discovery site.


2. Once the site is created, then you need to add Exchange one of the search result source so that your site can lookup for Exchange Online Mailboxes. To do that, you need to go to Site Actions-> Site Settings . Under Site Collection Administration , click on Search Result Sources.


3. Click on New Result Source.  Give a meaningful name and description. Under the Protocol section, choose Exchange. Next in the Exchange Source URL, click on Use AutoDiscover ( For on-premise, Exchange 2013 AutoDiscover should be enabled and working. For Exchange Online, its already enabled and working so you don’t need to do anything else). In the Query Transform, make sure the box is empty. Below is the snapshot for reference. Click Save and go back to home page


4. Create a case ( Test case is the same we use in this blog)


5. Fill in the required information for the creation of the case


6. Once the case is created, you will have Sources in the quick launch bar, in the left hand side. Click on it.

7. Click on New Source . You will find the below


8. For testing purpose, choose content type as Mailbox and click on browse icon ( present beside the check mailbox icon). Once click, below is what you will see



9. Just click on the search icon. If everything is done the right way, then you will see all the mailboxes that are currently available in your Exchange online tenant.


10.You can select the mailbox that you want in the Test case and use it accordingly.  If you are looking for add SharePoint site, it is pretty straight forward.  When you click on new source, you need to choose location in the content type and type the URL.

(Applicable to on-premise : In on-premise deployment, you can also add File Server location to search. But make sure that the file server location is already added as a content source in your search content sources.)
