We had (maybe still) have a problem that alerts don't work all the time. It seems that not for every edit or add action an alert is being sent to specific users. Unfortunately I could not reproduce this error although I did not receive some alerts myself. So I placed a call at Microsoft Support to help me out on this one.. I explained to them that this environment is an upgraded one (2003 > 2007) and that the alerts do work (so I don't have Ishai's problem). I got an answer from Holger Lutz (start blogging mate! ;) a SharePoint Support Engineer and he told me to take the following steps :
- Using STSADM to make sure that the alerts for that particular site are set properly:
stsadm.exe -o setproperty -url <http://yourserver/problemsite> -pn alerts-enabled -pv true stsadm.exe -o setproperty -url <http://yourserver/problemsite > -pn job-immediate-alerts -pv "every 5 minutes"
- Read the following KB article "E-mail notifications for alerts are not sent when content in a migrated list or in a migrated document library changes after you perform a database migration to upgrade to Windows SharePoint Services 3.0" and use the workaround that is given there "To work around this issue, use the following code to update the URLs of alerts in the Siteurl column of the ImmedSubscription table in the content database." (I wonder why haven't found this KB using Google.. although.. given the description of the KB it may seem logical that I didn't find it ;)
Now it's wait and see if the clients that reported the problem do not experience the same behavior as before..(it's a real bugger that the problem can't be reproduced since it's so random)
Update : got a tip from Servé to look at the following post : Sharepoint 2007 task notification alert emails not working
