I am looking to put SBS 2003 at home and have got the trial version going but not set the MX up yet.

I have few questions that I would like to understand first.. well more so, if anyone know this is achievable first.

Background: I have several email aliases on my current webhost which are pointing to a few external email address (like gmail) and some points to the mailboxes at webhost. There are 3 mailboxes with a combination of 6-7 email aliases/addresses to it. Two of the 3 mailboxes will be recreated on SBS 2003 as user. one will be a shared mailbox (but will this be a user?).

1) How do I recreate the email addresses that are pointing to other external email addresses, and how does one achieve this? for example: abcdef@mydomain.com is an email forwarder/redirector to abcdef@gmail.com.

2) How does the shared account (group@mydomain.com) be used by 2 users (acc1 and acc2, which both have acc1@mydomain.com and acc2@mydomain.com).

3) Some point later as well, I would like to use MS Exchange 2003 to ActiveSync with WM2003 devices, so personal email/calendar/contacts (acc1 or acc2) as well as the shared email/calendar/contacts (group).

4) With above setup, how many CAL would be used up you reckon?

5) It seems like Windows XP Home with Outlook 2003 can work well with MS Exchange 2003 but it loses connection to MS Exchange server from time to time... I know with XP Pro and connected to SBS Domain can solve this but the two laptops that we are using are XP Home.

I do hope someone will help me plan or guide me through this first part... I have been wanting to get this going for ages but haven't got the courage and right help to go ahead.

I thank you all in advance

Kel.
