Hi all!
Hope somebody can help me out. In my test lab, where I`m experimenting with Exchange 2013 SP1 and Outlook 2013 SP1 I came across very annoying thing.
Let me explain a little bit more about config that worked.
Outlook 2013 connected to Exchange 2013 via RPC over HTTPS is working great actually really great. I have created my own certs and imported ROOT CA cert to all of my machines and things are working peachy. As part of my plans for 2014 I have to test and deploy MAPI over HTTP sometime at the end of 2014 in our company (and migrate fromEX2007 but this is different story).
OK so I`ve enabled MAPI over HTTP on my test server and configured 5 virtual machines with different accounts to test things out. Started Outlooks, accepted "Your administrator has made change ....." prompts and here we go, I`m connected MAPI/HTTP and all works really great.
Except for one thing. When it does connect, things are super fast and it works as it should. But sometimes it does not connect right away and it is sluggish in performance. Also Outlook is missing "Quick steps" menu, see attached image:
I restarted all servers, clients, clean Outlook install nothing helps.
When RPC/HTTPS I could quit and start Outlook 10 times and it worked 10/10 without problems.
When MAPI/HTTP I restart outlook and it works 6/10, so 4 times I get messed up Outlook and very poor performance.
Any idea where to start troubleshooting? Maybe Outlook has a bug or 2 with this mode?
Server is correctly sized and backed up by enough of memory and CPU, mailboxes have 100-3500 items in them.
Again, RPC/HTTPS works every time without any problem.
MAPI/HTTP works lets say 6 times without any prolem at all and really works great but 4 times out of 10 it makes me want to throw it away :)
If someone knows best way to troubleshoot this one, please let me know.
Regards,
G
