Microsoft Exchange Server 2007 extended support will be ending 4/11/2017. So you may ask what does this mean for those of us running it? Basically it boils down to Microsoft saying we are done providing service packs, patches and updates for this product. If anyone finds a hack or a way in....you should have upgrade is the idea.
Here at Orion Solutions, Inc. we can help before that becomes an issue. We can help to determine what version you are running as well as assist in the upgrade and migration to either a new in house version of Exchange or even assist in Office 365 Exchange migration.
