Deployed first CAS/HTS 2010 yesterday. Win2008R2 SP1 and Exchange 2010SP2 All works fine.
All Mailbox users on Exchange 2007 for now.
Disabled existing Send Connector to Internet. Created a new Send Connector which uses one Exchange 2010HT Server only for now.
Issue:
Users send emails from OL2007/2010 it goes to Exchange 2007HT and then it sends to the SEND Connector on Exchange 2010HT.
The email flow is very slow between Exchange 2007HT and Exchange 2010HT.
When I add Exchange 2007HT to the Source Tab of the new Send Connector to Internet then the emails go out directly for Exchange 2007 users no slowness issues what so ever.
I would like to just have Exchange 2010HT in the Send Connector to Internet Source Tab and later will add another Exchange 2010 HT.
Question:
Why is email flow very slow between Exchange 2007HT and Exchange 2010HT.
When I was in school (to become an electrician) my teacher learned me 'meten is weten', roughly translated to English: 'measuring means knowledge'. :) So what you told here above is focussed at the symptoms. To understand better you should follow some messages with message tracking and then look at the headers to find out where the delay occurs. Also, have a look at the queues and find out if there are errors.
Do I add both Exc2007 and Exc2010 HTServer in the Outbound Connector to Internet or not? I notice placing both of them in there makes the mail flow faster.
Since we don't have any Exc2010 mailbox server yet ..I was thinking to increase the cost for Exc2010 Connector so all mail first flows through Exc2007 HT via the connector to the internet?
