Hi there, we migrated our Ex2003 months ago to a new Ex2010. We have several e-mail enabled public folders and mailing to them wasn't a problem (I thought so). Now it comes to my attention, that is impossible to mail to a specific public folder. Everytime a user sent a mail to this folder he get a NDN: --------------------------------------------------------------------------------- #554 5.2.0 STOREDRV.Deliver.Exception:ObjectNotFoundException.MapiExceptionNotFound; Failed to process message due to a permanent exception with message Der Ordner konnte nicht geffnet werden. 16.55847:CA000000, 17.43559:00000000A8000000000000000100000000000000, 255.23226:2F250000, 255.27962:44000000, 255.17082:BFF9FFFF, 0.25697:00000000, 4.21921:BFF9FFFF, 255.27962:FA000000, 255.1494:00000000, 255.26426:96000000, 4.18236:BFF9FFFF, 4.7974:BFF9FFFF, 255.1750:13800000, 0.26849:4F000000, 255.21817:BFF9FFFF ## --------------------------------------------------------------------------------- "Der Ordner konnte nicht geffnet werden" means "the folder could not be opened". What I tried: 1. Checking with adsiedit if theres a old "server container" as a result of the migration from Ex2003 to Ex2010. -> Container does not exist under "first administrative group.." 2. I can mail to all other public folders without any problems. 3. I "mail-diabled" them and "re-enabled" them without any success. Any Ideas? best regards

Match the permission of this folder with another working folder and post the result. Looks like its permission issue..little strange :)Gulab | MCTS-MCITP Messaging: 2010 | MCTS-MCITP Messaging: 2007 | MCC 2011 | Skype: Gulab.Mallah

Hi there, I tried already something with the permissions (forgot to mention) so they're "not default": ---------------------------------------------------------------------------------------------------------------- RunspaceId : 827651af-6bee-4c7a-a76a-b85be3a6bb5b Identity : \%FOLDERNAME% User : Standard AccessRights : {ReadItems, CreateItems, EditOwnedItems, DeleteOwnedItems, EditAllItems, DeleteAllItems, CreateSubfolder s, FolderOwner, FolderVisible} RunspaceId : 827651af-6bee-4c7a-a76a-b85be3a6bb5b Identity : \%FOLDERNAME% User : Anonym AccessRights : {Author} RunspaceId : 827651af-6bee-4c7a-a76a-b85be3a6bb5b Identity : \%FOLDERNAME% User : %USERNAME% AccessRights : {Owner} ---------------------------------------------------------------------------------------------------------------- best regards Christoph

Hi Chris, I forgot to ask that is it happening with one specific user only or with all the users(not able to send email to this folder)?Gulab | MCTS-MCITP Messaging: 2010 | MCTS-MCITP Messaging: 2007 | MCC 2011 | Skype: Gulab.Mallah

Disable the Folder and wait for sometime and Mail Enable it again...Post the result...Gulab | MCTS-MCITP Messaging: 2010 | MCTS-MCITP Messaging: 2007 | MCC 2011 | Skype: Gulab.Mallah

Hi, I already did that in the past without any success. I disabled the folder for at least 2 hours. best regards

Hi, I disabled the folder for nearly 18 hours, problem is gone. Thank you! best regards
