Hi!
I've migrated from Exchange 2010 to 2013 last month. Since then, my users cannot download the OAB externally (internally and via VPN: working correctly) and mailtips aren't working externally (intenally and via VPN: working correctly).
Test-Outlookwebservices shows "success" for all tests. "Test Email Autoconfiguration" in Outlook 2013 shows the correct URL for the services. Outlook connects using mapi over http but the same issues exists when using RPC over http.
Anyone can help me??
Kind regards from switzerland!
