Cause

This issue occurs due to the changes in the Outlook 2016 architecture that does not create the MAPI attribute "ROHFLAGS_USE_ROH"  when Outlook 2016 connects to Exchange 2010 mailboxes. This change causes the Enterprise Vault client add-ins do not detect RPC over http,. which does not fail back on the 'RPC over http proxy URL' specified in the desktop policy.

Workaround

1. Install Outlook Spy > Open Outlook & select 'RPC-http' profile.
3. Click on the IMapiSession button on the Outlook Spy toolbar.
4. Click on OpenProfileSection.
5. Scroll down and select pbGlobalProfileSectionGuid.
6. Add property, Tag = PR_ROH_FLAGS,Value = 7, click OK. Restart outlook.
