Configuring incoming mail on Microsoft Office SharePoint Server 2007 (MOSS 2007) and Microsoft Exchange Server 2007 took a little bit of fiddling about with and quite a bit of standing back, scratching my head, and going um and ah. However, with a bit of enthusiasm and lots of determination I finally got it working. Here’s how.

I configured the MOSS, Configure Incoming E-mail Settings, screen easy enough. The key fields were:

• Active Directory container where new distribution groups and contacts will be created
• SMTP mail server for incoming mail
• Accept messages from authenticated users only

I decided to refine the other settings later, when thing are up and running.  This MOSS screen image can be seen below:
Next, I headed into the IIS Administrator and in particular to the default SMTP Virtual Server under IIS. In the section “Relay Restrictions” I granted access to the Exchange Server so I had to put in the IP address of the Exchange Server, as shown in the following image:

A quick check on the Active Directory Controller showed the Active Directory Container name successfully appeared and I was able to set an email address against a document library.

On the Exchange Server it was a fairly simple matter of creating a Hub Transport Send Connector and choose a suitable smart host authentication method for communications between Exchange and MOSS. The Address Space Tab showed the moss.domain.com address. The network tab was told to route all traffic through the following smart host: moss.domain.com and the source server was the Exchange Server.

A test message from Outlook to jasonmoss @ moss.domain.com was sent and a few moments later it appeared in the Document library.

Separately all the tasks were straight forward enough – its just a pity that it isn’t that clear where all the fields are that need ticking or setting. Now I just need to get Outgoing Mail from MOSS working!
