Email enabled document libraries stop receiving emails
We have encountered issues related to email enabled document libraries stop receiving emails.
After investigations listed below is the synopsis of the issue.
Background
- Intermitently we have encountered (on different environments) issues with email enabled libraries stop receiving emails
- Emails enabled document library successfully received emails for months
- Suddenly document library stops getting emails
- Within the configuration of the doc lib, we see that the doc lib is still email enabled, but it would not received emails
- Within the ULS log there is a message “The following aliases were unknown: XXXX” as SharePoint cannot verify\locate the email alias
Result
- Emailed enabled document library stop receiving emails
- As SharePoint does not send back notifications for emails it could not process, sender is unaware that the emails did not reach its destination in SharePoint
- Within document settings, the document library still shows as email enabled
Cause
- A triggering event (at present this is unknown as we cannot recreate it in dev\test) causes email alias to be marked as deleted within MOSS_CONFIG.EmailEnabledList table
Fix
- Disable and enable again the email setting within the document library
- Run “stsadm –o refreshdms –url <web application url>”. Note: This command will re-sync and enable all email enabled document library present within a specific web application.
Workaround
- Until we are able to identify the triggering event, we are
- Proactively monitoring the MOSS_CONFIG.EmailEnabledList table to check for any email enabled list with Deleted column = true. This is an indicator that email enabled document library may not be receiving emails.
- If we encounter such a scenario, then we run “stsadm –o refreshdms –url <web application url>” noted in the Fix section above or reset the email enabled setting
Currently looking into the triggering event, hence if we find one, I will post it.
