Hi All
We are in process of migrating from Exchange 2007 to 2013. Clients are Outlook 2013.
Users who are migrated to 2013 are experiencing outlook timeouts regularly throughout day (we do not run in cache mode).
I am noticing that Outlook Connection is reporting slow response times for Exchange Directory connection (screen shot shown below) i.e. 1000ms or above. All other connections are fine.
When outlook times out - I notice that connection to Exchange Directory is the one that times out also.
I suspect a GC / DC issue - perhaps Exchange is querying GCs outside of site? and that's causing timeout? WAN connections between sites are slow (1.5Mb or below).
But my AD team tells me there is nothing wrong with infrastructure. :-)
Could someone assist me in identifying the cause?
Thanks in advance
Anthony
