I can't create alerts to be notified of changes to Web content

• Is the Alerts feature turned off?  A server administrator must turn on this feature before you can use it. See "Configure alerts for a virtual server" in Windows SharePoint Services Help.
• Is the Windows SharePoint Services timer service turned off?  A server administrator must turn on this feature for Alerts to function. See "Schedule timed jobs" in Windows SharePoint Services Help.
• Does the site group to which you belong have permission to create alerts?  See your server administrator for information.

Alerts are sent to the wrong e-mail address

• Was the correct e-mail address specified when you were invited to the site?  You may need to update your account information. See "Modify user account information" in Windows SharePoint Services Help.
• Are the alerts being sent to the mail account you use for instant messaging?  When you enable instant messenger integration, the e-mail address that you specify is also used for alerts. See "Configure online presence information" in Windows SharePoint Services Help.

I removed a user from a site but he or she is still receiving alerts from it

When you remove a user from a Web site, site group, or cross-site group after he or she has created alerts, you must manually delete any alerts that he or she has set up. This is also true for any lists or libraries where you change security settings to limit access. If a user has set up alerts for the list or library, he or she will continue to receive them after you change the security settings. For information on deleting alerts, see "Delete an alert" in Windows SharePoint Services Help.

Note  To delete an alert for another user, you must a member of the Administrator site group or a site group that has the Manage Web Site right.
