In Exchange 2010 

- Mailbox with a default email of ITHELP@domain.com

- added an alias of DEVELOPMENT@domain.com to the ITHELP mailbox

In Service Desk Plus  9.3  Build  9307

- Admin...Org Details...Mail Server Settings - i've added DEVELOPMENT@domain.com as an alias to fetch.  I've stopped/started fetching

- Admin...Users...Support Groups -  i've created a group DEVELOPMENT and entered DEVELOPMENT@domain.com in the Group E-mail field

When I send an email to DEVELOPMENT@domain.com the ticket gets created but does NOT get auto-assigned to DEVELOPMENT support group

Note:

If I create another another support group and give it the Group E-mail ID of ITHELP@domain.com, it works fine.  The ticket gets auto-assigned to the ITHELP group.  It seems it's having a problem with alias email IDs.

We are using POPS to fetch emails if that matters.

Thanks
