we have a scenario where there are two mail servers for different domains running on different e-mail platforms. One is an Exchange 2016 server, the other one is a Kerio Connect server. Now some of my users have e-mail addresses on both servers and want to use them together in their one Outlook instance and, of course, the same profile - so they have, for example, all their calendars from both servers in one view.
Kerio Connect provides a software called Kerio Outlook Connector which is basically a custom MAPI provider plugin for Outlook, while connection to the Exchange server is established the standard way of autodiscover which supplies Outlook Anywhere or MAPI/HTTP.
Now when I set up both a Kerio and an Exchange account in the same Outlook profile, it basically works, but there are some issues which I have already described in this thread at Kerio's support forums..
While this may not be a supported scenario at all for Outlook, I'd be thankful for any hint that helps me making it work nonetheless.
For example, does Outlook for Windows support EWS? Could I set up the Kerio account as EWS account in Windows Outlook, not using the Kerio MAPI provider plugin at all? I already tried to set it up via ActiveSync, which basically worked regarding the problems I had before, but EAS really is optimized for mobile devices - many mails with attachments don't get synced, shared or public calendars are a problem (getting reminders from all subscribed calendars all of sudden because ActiveSync doesn't make a real difference between "own" and "other" calendars), and so on..
Or is there any other way I can configure Outlook to respect the separation of the two accounts - in terms of transport providers, Free/Busy queries and so on?
I didn't find the right solution from the Internet.
