Here's my set up:
Sharepoint Foundation 2010
Exchange Server 2007
Windows Server 2008
A system-generated email is sent okay when creating a new Farm Administrator in Central Administration, but when creating a new Member on our Team Site, I get the following error:
The user or users have been added successfully, but there was an error in sending the e-mail message. The server may not be set up correctly to send e-mail. To verify that e-mail is configured correctly, contact your server administrator.
Here is what I've tried:
1. Creating a new Receive Connector as described at http://sharepointgeorge.com/2010/configuring-outgoing-email-sharepoint-2010/
2. Checked settings at Central Administration > Web Applications > General Settings > Outgoing Email: Have tried both the IP address for my Exchange/Sharepoint server (e.g. 10.1.10.11) and my regular mail.xxxx.com smtp address with the same results.
3. Checked settings at Central Administration > System Settings > Configure outgoing e-mail settings: Have tried both the IP address for my Exchange/Sharepoint server (e.g. 10.1.10.11) and my regular mail.xxxx.com smtp address with the same results.
4. Confirmed that I can connect to my Exchange server using telnet
As I said, email from the main admin page (Central Administration) seems to work fine, but it doesn't work when setting up users on my Team Site. Exchange server works fine for our corporate email--it just doesn't seem to work with the Sharepoint team site.
I've run across advice to check Exchange logs, but have no idea where to start.
