Exchange 2010 and user multiple SMTP address' defined on their "e-mail address" tab
Posted on 2013-01-08
A quick overview. Have an SBS2011 server running Exchange 2010 that until recently was using POP for main email communications. Just brought everything inhouse and all email operations is now running off Exchange 2010.
While still using POP from a 3rd party, add'l SMTP addresses were created for a certain subset of users, so that their personal web-based (att.com / gmail, roadrunner, etc) would display in the Global Address List. Everything worked fine when selecting theirwebased accounts as far as addressing an email to that account, and sending/receiving on that account.
However since redirecting all email to the inhouse Exchange, when a user who has a web based SMTP account defined under their Exchange Email Address' tab, (recipient configuration > mailbox > user "email address' tab) tries to either send or forward an email to that web-based account...they don't receive it there. It gets sent but comes right back in on their Exchange account. It never arrives at their g-mail account (as example).
Could use a pointer or two on what to look at. I"ve not been able to even phrase a search argument on this odd-ball to make any progress. Thanks much for any assistance.
