I have an error popping up every time I try to email to my SharePoint list. The event is a warning and says: An error occurred while processing the incoming e-mail file c:\inetpub\mailroot\drop\2d96285501ca933b00000008.eml. The error was: Unknown alias..This feature used to work and I'm not sure what occurred to make it stop working. I have SharePoint 2007 installed on a Windows 2003 R2 sp2 x32 server. We are using Exchange 2007 to email to the server. I have SharePoint patched to Service Pack 2 but I haven't applied any of the hotfixes.I can email the server and can watch the message pass from the Exchange server to the SharePoint server. I can see the message in the Drop fold briefly but after about 30 seconds the message vanishes and the document never shows up again. At this point I log the error and that's all I see.I've read several posts but nothing has helped so far.I have checked through the various hotfixes and it looks like one from December (I think) may help but since service pack 2 came out after the original hotfix, I'm a little leary to try this approach. If I did attempt to use the older hotfix would I then re-patch the server with sp2 once again.Thanks for your help.-Stone

Hi Stone, SharePoint stores the email alias information in both configuration database and content database. When email alias information between these two databases doesn’t match, event ID 6873 will occur. To walk through this issue, please run command “stsadm -o refreshdms -url <URL>” to synchronize email alias information. For details about this issue, please refer to:http://blogs.technet.com/vinitt/archive/2009/07/15/e-mail-enabled-list-alias-information-is-not-synchronized-between-configuration-database-and-content-database.aspx Best Regards.

Thanks for your help Lily but unfortunately it didn't solve my problem.When I run the command that you have listed I get an error that states: "There was an error in the application." or something really close to that.Do you have any other advice for me?Thanks.-Stone

Hi Stone,Would you please provide more detailed information about the error?You can also check the ULS log for clues which will help to further investigate this issue.Best Regards.Lily Wu

Hi! We have the same problem here after content database migration to another farm. Everything works fine with new aliases, but existing aliases fail with "Unknown alias.." “stsadm -o refreshdms -url <URL>” fails with "error in application". The corresponding ULS log entry (even though it's in German I think you will be able to look into the exception) 02/17/2010 10:38:57.03 STSADM.EXE (0x154C) 0x16E4 Windows SharePoint Services General 72ju Medium stsadm: Running refreshdms 02/17/2010 10:39:01.59 STSADM.EXE (0x154C) 0x16E4 Windows SharePoint Services General 72ju High stsadm: Fehler in der Anwendung. Callstack: bei Microsoft.SharePoint.SPList.UpdateDirectoryManagementService(String oldAlias, String newAlias) bei Microsoft.SharePoint.SPList.Update(Boolean bFromMigration) bei Microsoft.SharePoint.SPList.Update() bei Microsoft.SharePoint.SPSite.RefreshEmailEnabledObjects() bei Microsoft.SharePoint.StsAdmin.SPRefreshWebAppDirectoryManagementService.Run(StringDictionary keyValues) bei Microsoft.SharePoint.StsAdmin.SPStsAdmin.RunOperation(SPGlobalAdmin globalAdmin, String strOperation, StringDictionary keyValues, SPParamCollection pars) Any ideas how to solve this? Thank you in advance.

Hi Stone, i had the same error message when a unkown mail was adressed to an receiver adress which was not binded to an sharepoint list or library. To verify this you can watch the Virtual SMTP Server Log from the IIS. You have to activate the logging and extend the logging options under logging properties to see the receiver adress in the log.
