we use mostly outlook 2010 and little 2013 as client application. we have exchange 2013 cu3 (on -premise servers) - cas servers with mailox and transport roles..
for 2 months from time time our users are experiencing Outlook freezing problem. It mostly happens when you click send button in order to send e-mail or when you switch between e-mail and calendar.
we are getting crazy about this problem. do you have any idea.
what we have tried so far is:
1- we checked the server side logs. nothing found.
2- we change the outlook log level in order to get more detailed logs but from this logs we couldn't capture anything.
any recommendation will be highly appreciated.
