We've using SDP+ and Exchange 2010 server.

When SDP was implemented to our system, only IT dep was using it, but, the service desk is such a good solutions, so we've decided to implement it for a tech support, security support etc..

So, the main problem is SDP+ can receive emails only from 1 emailbox: (ex. support@company.com), so for different groups we must create an alias for support@ such as: security@ etc.. 

But the problem is, in exchange 2010 we can't create an alias that we'll be shown in GAL (address list), I don't need to write email, I just whant to choose it from drop down contacts list and send it to support group.

How can we solve such problem?
