Hi, there is any problem or any prerequirement if i want to install SP1 for exchange Server 2007on Edge. thanks

Check by running ExBPA on edge server, if MS suggest anything. If you are running ForeFront on Edge make sure you upgrade it to SP1 first. http://www.microsoft.com/downloads/details.aspx?FamilyID=2ceb14d4-404b-4d8f-8a21-ebfc71b2e82b&displaylang=en Follow below link for Safe shutdown of ForeFront before you install Exchange 2007 SP1 http://support.microsoft.com/Default.aspx?kbid=929080 Stop all Exchange Services and install SP1. Start the ForeFront safely. Restart the server to make effect.

Thanks Amit,
