A customer of us has Kerio connect (8.5.3) installed on a Windows Server 2012R2 server.
There are 15 mailboxes currently in use and all of them have got the same problem which is:

Sometimes when starting outlook, it hangs at "Loading profiles" (takes +15 min). When you kill it a few times and start outlook in safe mode (which is sometimes also this slow, so it looks like that the connector is not the problem in the slow boot) and than again in normal mode; it will eventualy load fast(10 seconds). But this is, offcourse, not very user friendly for our customer.
Searching is sometimes also very slow; some times it freezes Outlook and it takes for like 20 minutes to return the results.
But if you do another search a few seconds after that (searching something else, unique) than its quite fast again.
It looks like; everything that loads for the first time after the computer boots or when the computer is not used for a while is very very slow.

What did we do?
-We disabled all plugins in outlook except kerio
-We enabled synchronizing all the attachments
-Windows Search indexer disabled on outlook folders
-Replaced the server name (where the connector connects to) for an IP-address (to exclude DNS problems)
-We also looked into the logs, but we didnt find any suspicious.
-Disabled antivirus (trend micro)

What kind of clients do we have
-MS Windows 7 (Intel i5, 8GB memory)
-Outlook 2010
-2 Kerio emailaccounts configured per Outlook + 1 POP account (not popping, but only used for sending through a specific mailaddress. I know it sounds creepy, but thats what the customer wants...)

What did we find suspisicious..
-When outlook starts and hangs at "loading profile" and kill the koff.exe process, it immediatly loads the Outlook (but without any content... no emails etc.)

We also have terminal server with 2 accounts (Server2012R2 with outlook 2013). Its the only computer that doesnt have this problem.

We are trying to switch from Exchange to Kerio for other customers also, but this is not really the results we've expected for a complete new environment.
Does anyone have a suggestion to fix/troubleshoot this problem?
