Our 3 year old Exchange 2007 Server license is going to expire as of this month (February). We decided to upgrade to Exchange 2010 to save costs in licensing. (1 Exchange 2007 Enterprise license in exchange for 2 Exchange 2010 Standard licenses - previous administrator did not evaluate corporate needs appropriate and over-licensed). We are in the process of relocating a server from one location to another then this will be used to install W2K8 and Exchange 2010 but that won't happen for another couple of weeks.What is the grace period for current Exchange 2007 Server licenses that are set to expire? Does the 120-day trial rule apply to this? Will we lose Exchange 2007 functionality? I am hoping there is a grace period that'll give me time to get Exchange 2010 installed and migrate everything to that then remove Exchange 2007 from our organization without negative consequence.If we are going to lose Exchange 2007 functionality, then I probably will use the Exchange 2010 trial version on a group of temporary servers until we can get our permanent server in place but this is obviously a last resort.Thanks for your response!Meg

There's no expiry built-in to Exchange. It will continue to work. If you have ForeFront doing anti-spam or anti-virus, I think that is however tied to a contract.Active Directory, 4th Edition - www.briandesmond.com/ad4/
