After migration to MSS2010, we realized that the alerts, that we used to send to a distribution group in our company, do not work. There was an option to create alert for the group (e. g. group_all), assign an e-mail to the group and add permissions for this group to the web site and the alerts started working. When I do that in Sharepoint 2010, nothing is sent, not even the initial e-mail.
Sending SharePoint 2010 alerts to an Exchange distribution list.
- Create the distribution list/group in Active Directory and assign an email address. Do not use any dashes "-" in the group name.
- Edit the properties of the group to change its Group Type to Security (from Distribution). Make sure the group is a Universal group. Only security groups show up in SharePoint's address book. They show up as "domain groups" in SharePoint.
- Give the domain group at least visitor permissions on the list that are you are creating the alerts for in SharePoint. Alerts won't be sent if the domain group doesn't have appropriate permissions.
- Then setup the alert and use the address book to locate the domain group.
- Test out your alerts. If you have "require approval" turned on for the list, make sure you approve the items so alerts will be sent.
Were any other changes made outside of SharePoint? I know Exchange has an option to set distribution groups to only be available for use by "authenticated or trusted senders" (this prevents email/spam from the internet from being sent to internal distro groups). We ran into this problem, because SharePoint does not "authenticate" to the Exchange server, it is not, by default, trusted/authenticated.
