We have installed SP3 in the Exchange Server 2007 form an SBS 2008 Server and we would like to know : -- How can we check if our version has now the SP3 installed ? The version is now 08.03.0083.000 -- Is it recommended to install Rollup 4 for SP3 ? -- Is it Rollup 4 the latest for Exchange Server 2007 SP3 ? Thanks in advance I remain Joaquim Palomares TECMAN Serveis Informatics jpalomarestecman.net

Hi, The version number 08.03.0083.000 tells us if that you have SP3 installed. SP2 had 08.02.XX and SP1 08.01.XX. You can see the build number if you run Get-Exchangeserver | ft in Exchange Managment Shell. You can also find the buildnr in KB158530I Would recommend you to install the latest RollupNo, the lastest Rollup for Exchange 2007 SP3 is RU7 and was releases one moth ago. Can be downloaded here Martina Miskovic

Hi, We always recommend to install the latest update for Exchange Servers. For version, I recommend to run get-exchngeserver. Besides, we can verify the update from "Add/Remove Program" How to determine the version number, the build number, and the service pack level of Exchange Server http://support.microsoft.com/kb/152439 Xiu Zhang TechNet Community Support

Hi Martina Thanks for your reply. We have allready upgraded SP3 and Rollup's and all is working fine. But we also need to resolve this issue : we have a Mail Domain ended tecman.net and we have users inside the company and users from the SBS domain using the external pop3 mail and all working fine. But we have other users from our isp mail server ended also with the same domain, and we cannot not send mail to them because the exchange server rejects them. Because they are not domain users. Is there any way to tell the exchange server 2007 to ignore some mail users and send them using smtp/pop3 ? Thanks in advance Joaquim (TECMAN BCN)Joaquim Palomares TECMAN Serveis Informatics jpalomarestecman.net
