MS Server ActiveSync doesn't work for Exchange 2010, what shall I do?
This is using altogether 5 Exch 2010 (w/sp1) servers. 3 CAS, 2 HT/MB. CAS is using NLB. Recently, found that my handphone stopped to receive any incoming email. How should I troubleshoot to get whole thing back in life again.
First of all you are running unsupported version of Exchange. You have to upgrade to Exchange 2010 SP3 ASAP.
Please test activesync https://testconnectivity.microsoft.com/ and check for errors in the result
