Hi

Please I have been refered to the Exchange 2013 forum Support team by the SharePoint Team to resolve a complex issue that is unfortunately taking quite some time to resolve. I currently manage a Sharepoint 2013 environment. I have a requirement to configure and enable the creation of site mailboxes. 

So, I have Sharepoint 2013 installed on A.contoso.com which has all the user accounts( Account Forest). As a means of using the Sharepoint 2013 site mailbox feature, another domain( resource domain) called B.contoso.com has been created. Exchange 2013 has been setup on B.contoso.com. All the lengthy services on Sharepoint and Exchange 2013 have been configured. A two way trust has been established between both domains. I am able to access resources both ways. On the other hand, when ever I or a user tries to access a site mailbox it prompts that a mailbox has been created and then takes you to the OWA page of which login credentials don't work. I'm having to now create a linked mailbox and specify the users account in the accounts domain in order to enable a user login to the created site mailbox. Furthermore, When, I access Exchange management Center I don't see the site mailboxes listed. I only see the linked mailboxes for the account holders. I am only able to view the site mailboxes through powershell. 

Please, I would appreciate it if anyone can help.

Dominic
