Situation

• New SharePoint deployment.
• Outsourced IT operations.

Problem

SharePoint alerts not working for users.

Cause

Outgoing email address is configured to support@serviceproviders.email. This mailbox is not configured on local SMTP server (Exchange 2003). Hence SharePoint cannot send email via Exchange as open relay is turned off; as it should be.

Solution

Outgoing email address should be configured to local.user@mycompany.com -an active local mailbox. Test that you can access local.user mailbox either through Outlook Web Access or Outlook client.
