I'm connecting sbs exchange 2003 to gmail which is working but sending emails shows the name of the person correctly but from email is the email address making authentication. &nbsp;I'm converting to passing email through gmail because we can not afford junk mail filters/virus filters for exchange and they are getting blacklisted because of this. Other problem is I can't convert to pop3 accounts because of shared calendars already in exchange and not converting the calendars to gmail. &nbsp;They decided gmail calendars were more cumbersome then outlook/exchange. &nbsp;<br />

Anyone know how to get around the authentication/from email issue?

Connect Exchange 2003 to Gmail

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

Email Protocols

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.
