ActiveSync Connection Speed

Post by jeffhsu » Mon Jul 23, 2018 9:23 am

I have ME Premium 10.16
My server and Internet speed is not that slow, the resources used is always about 20%
but I notice the ActiveSync email are always Waiting for server response in Outlook and seems to be always trying to connect, seems slow
Other services like POP, SMTP, IMAP connects pretty fast.
Kindly advise how to speed up the process or what caused it to be slow?
