Hi.

Whenever a user sends an e-mail from a mail-enabled public folder, we get event ID 2009 in the eventlog on the server.

Here is an example:

[Process:Microsoft.Exchange.RpcClientAccess.Service PID:8508 Thread:21] Error occurred while resolving the Active Directory object for from email address field: '/CN=Mail Public Folder/CN=Version_1_0/CN=e8220731-f0fa-4ddc-8468-b4c0b03fd014/CN=00000000F9EEE5CC0E1CEA4399F554BE45C282950100553B1102F06969459294143534D98B4D0001030A79E30000'. Audit log will not be generated for this case. Exception details:
Microsoft.Exchange.Data.Storage.ObjectNotFoundException: The Active Directory user wasn't found.
   at Microsoft.Exchange.Data.Storage.ExchangePrincipalFactory.FromProxyAddress(IRecipientSession session, String proxyAddress, RemotingOptions remotingOptions)
   at Microsoft.Exchange.Data.Storage.ExchangePrincipalFactory.FromProxyAddress(ADSessionSettings adSettings, String proxyAddress, RemotingOptions remotingOptions)
   at Microsoft.Exchange.Data.Storage.ExchangePrincipal.FromProxyAddress(ADSessionSettings adSettings, String proxyAddress)
   at Microsoft.Exchange.Data.Storage.COWAudit.GetSubmitEffectiveMailboxOwner(MailboxSession session, CallbackContext callbackContext)

The mails are sent correctly, but transport rules are not applied to them. So as we have some transport rules that copy mails with specific recipients, this is a problem.

The only references I can find to this error are related to not being able to send to the folder, and does not seem to apply to my situation.

Look in the Microsoft Exchange System Objects container using ADU&C with View Advanced to see if your mail-enabled public folder objects are there.

Hi.

Yes the folders are shown in there as type publicFolder. This appears to be happening for all our mail-enabled public folders, when using send-as in outlook. The error appears in the eventlog whether transport rules apply or not.

Is there any other information I can provide?

So maybe you have a rights issue.  Have you verified that the sender has rights to send as?

This article is for Exchange 2010, but I would think it's the same for Exchange 2013 although I haven't tried it.

Yes, the users have the needed rights and as I wrote in the original post, the mail is sent, but the event is logged, and transport rules are not triggered.

Hi,

For your question, how this issue reproduce on other public folder? Ensure whether this problematic public folder is upgrade from previous Exchange.

If this issue only occur on special public folder, please try to mail-disable it for testing. For your reference:

Or you can re-create new public folder for tesing. Here's an similar thread about your question, please refer to:

Thanks

Hi.

This happens on all mail-enabled public folders where someone is allowed to send-as. (This only appears when someone is sending as the folder)

I have tried creating a new mail-enabled public folder, assigned myself as owner of the folder, and given myself Send-as and Send-on-behalf rights. I then proceed to send an e-mail that is delivered correctly to the recipient, both internal and externally, but the event is logged and transport rules are not triggered.

The Exchange system was upgraded from Exchange 2007, but that was more than a year ago. Unfortunately I am not sure if this error has been happening all the time or if it has just begun.

I am currently using Exchange 2013 CU9.

Jens
