Exchange Server

Hi,

I have written an Event Sink (OnSyncSave) that processes all incoming
messages (in a public folder) modifies a few of their fields, and adds
another two.

The sink was working perfectly, until I had a user copy messages from
his Inbox into the public folder. There strange things started to
happen:

For SOME of the copied messages, I get an error (described below) when
doing any operation on the fields. I include the relevant code below.
I've almost pulled all my hair out! I've used Exchange Explorer to try
and locate any differences between the messages that cause the error
and those that don't but there's nothing different!

I have also noticed that no matter how many times you copy the message
from the Inbox to the public folder, the same error occurs. This would
mean (I assume) that there is something wrong with it, and that the
error wasn't a freak one.

Thanks

You can't jump stores in Exchange due to a security restriction so when the
sink tries to retrieve properties from the original message in the inbox
(and it's logged onto the public folder store), you will get the error
you're seeing. If you create another connection to the inbox using ADO,
then you should be able to copy the values between the two.

Hi Tom,

Thanks for the reply,

Your explanation sounds logical, however I am not manually copying
messages from the Inbox to the Public Folder within the sink.

The user copies the message himself (by drag & drop), and the
OnSyncSave event fires for the copied item, just as it does for any
other incoming message.

As I wrote, this error happens when copying SOME messages only. i.e.
If the user copies 10 from his Inbox to the Public Folder, then about
2 or 3 give me the error.

The messages that give me the error, are not random. i.e. If I delete
them from the Public Folder and I recopy them, they still cause the
same error, no matter how many times I do this.

I am convinced that there is something about those messages that
causes this. I still have no clue however. Any other ideas?

Thanks
