Please help urgent

hi, >>>later on i found out ms exchange replication services keep restarting it own with error 4999. Please post the whole error here. >>>While i change the clientaccessrpc server from cas1 to cas2. Why do you change the cas servers? What's the cas1 and what's the cas2? I guess cas1 is your exchange 2007 cas server, and cas2 is your exchange 2010 cas server, is it right? If you change the clientaccessrpc server back, can the moverequest work? I recommend stop the moverequest, and change the server back, then do the move request again. hope can help you thanks, CastinLu TechNet Community Support

i need to change the exchange 2010 cas1 to exchange 2010 cas2 due to some issue. Both is in new exchange domain. I try move the other mailbox on today, it is working. but the cas1 still showing msexchangemailbox replication service keep on restarting. and the 2 old queue hang at 99%, and i not able to remove it. anyone face issue on exchange 2010 version 14.2(build 247.5) with msexchangemailbox replication service keep on restarting itself?

manage to solve the issue by removing latest update RU4. MS support said is a known BUG with Exchange 2010 RU3 and later versions.
