Hi,
Exchange 2010 is running in present environment and recently I have introduced Exchange 2013. There is federation Enabled at Exchange 2010 end with External Exchange organization. When we migrated users from E2k10 to E2k13 Free /Busy sync has stopped working.
Exchange 2k10 & E2k13 in same Exchange organization and no errors found in configuration part and all seems Success.
Here what I am suspecting, something that I need to do at F5 load balancer end, not sure what :( .. I need urgent help from Experts in this forum to help me in case I have missed something to make Federation working.
