we have this configuration
2x DC 2012
1x Exchange 2013 CU10
1x Kemp (virtual) with ESP
When Connection Outlook via Kemp (and autodiscover) everything works fine. Mails, Calendars, everything.
Except one Thing: if I use Outlook 2016 I can´t download the offline address book. The window appears but nothing happens
If I use Outlook 2013 everything works fine
Are the new (?) virtual Services when using Outlook 2016 and Exchange?
