OWA Automapping

Good Afternoon Everyone!

We are utilizing Exchange 2016 CU5 (on premise server) and noticed an issue in Outlook Web App (OWA).  When we add shared mailboxes with Full Access, the mailboxes will propagate properly (via Automapping) in Outlook 2016.  However, when the user logs into OWA, we see that the shared mailbox does not properly populate in OWA.  In fact, it seems like OWA is showing the same shared mailboxes before our 2013 migration.  

We tried playing around and removed access for one of the shared mailboxes that were listed there.  It properly removed them in Outlook 2016 but did not remove them in OWA.  This seems to be an organization wide issue as we are able to replicate this issue under all the mailboxes we've touched so far.  We are pretty stumped as there doesn't seem to be a similar case online.  

Attempted Steps to Rectify the Issue:

* We tried recreating the OWA virtual directory with no effect.  

* We tried removing the users from the shared mailbox and readding them as Full Access users under Mailbox Delegation.

* We also checked the msExchDelegateListLink attribute for the shared mailboxes to ensure the users are listed there.

Any other ideas would be much appreciated!  Thanks.

HI Edward,

I think it is by design. In OWA you need to open shared mailbox manually form right click your account then choose open other mailbox.

Unfortunately Automapping feature is limited only to Outlook

Not sure if this is true.  How are these shared mailboxes automapped in OWA then?
