I am usingExchange 2007Version: 08.03.0348.002. Trying to email (external sender) to mail- enabled Public folder. All emails get to the folder without issue. Failed email from a specific email address. The Public Folder has the Anonymous account set asan Author now - I changed it to that after finding an article similar to my issue. That did not resolve the issue.
Error message reads: 550 5.2.0 STOREDRV.Deliver: The Microsoft Exchange Information Store service reported an error. The following information should help identify the cause of this error: "MapiExceptionNotFound: 16.18969:99070000, ....". Internal Message 5171576.
Any ideas why it would fail to deliver from a specific email address (domain)? It is getting to the Public Folder on delivery but fails to write the message - I think. It would seem to do with the sender's email...
