Serveral Connection Issues With Outlook 2016

We have deployed a few Office 2016 Standard installs and we are seeing some very strange issues.  If you leave Outlook open for an hour or longer it will freeze up or the screen will go black when you go to access it.  If you wait long enough it will come back, during that time a bubble will pop up in the lower right corner of Outlook telling you "trying to connect to CAS".  Also, often and hard to reproduce is if you try to access the Address book you will get an error telling you it can't access the address book.  You close the error and try again it will open or you may have to close it a couple of times.

We have an on prem exchange 2010 server and 2013 and 2016 clients, no 365.  We also use auto-discovery and it seem to me setup correctly don't get any errors about that.  I say it seem fine because when we went to Exchange 2010 Microsoft did the install and setup.

We are lost, any help or direction would be greatly appreciated.

Thanks
Wade

Both and not all the time, I am leaning on this TCPIP keepalive but the issue is that the exchange server does not have the reg key in question so I am wondering if the key is not there is it the default of 2 hours?  I have also talked to our Firewall guy to see if there is a setting in there for a keepalive and that way we can start from there.  We are going to contact Microsoft.

Just internally, Exchange 2010 no sp or roll up?  During our down time in a few months.

Hi,

I will recommend you to install SP3 and one of the latest rollup 18.

It always better to have the latest version in order to avoid connection problems.
