2011-07-04 09:04:32 (#5268): The category of the message is 'Unknown'.

2011-07-04 09:04:32 (#5268): The message was not processed because its category is not supported: Unknown.

Any thoughts? Thanks much!

I sounds as if you can easily reproduce the problem. Please perform the following steps:

-Enable trace logging and message logging (Log processed messages & Log ignored messages) on the server.

-Send one or more messages to reproduce the problem.

-Disable trace logging and message logging.

-Send me the compressed content of the folder <InstallDir>\Diagnostics and tell me the sender and recipient addresses of the test messages.

I analyzed the MAPI-messages and noticed that the MAPI-message-class is "IPM.Note.Default" instead of the standard IPM message-class "IPM.Note". This explains why DisclaimIt does not process such MAPI-messages.

The message-class "IPM.Note.Default" is used when a custom message form is used as replacement for the default global message form (see http://msdn.microsoft.com/en-us/library/bb176910(v=office.12).aspx ).

Are you aware of the use of such a custom global form or is it a left-over from an older Exchange environment?

-Franz

Yes, DisclaimIt 4.x is a completely new implementation. It doesn't contain any code from 3.x.

>Is there a workaround for this?

Not with DisclaimIt 4.x. While it would be possible to add support for messages with non-standard IPM message classes to a future version, I'm vary of going this way because you don't just know what's the content of such messages. For more information about restrictions and risks of using a global custom form, please read http://support.microsoft.com/kb/241235/en-us .

I would suggest that the company reconsiders the use of their global custom form. Do they still know why they implemented this solution many, many years ago? ;-)

-Franz

I expect to release the next version within this month.

-Franz

DisclaimIt 4.6 has been released.

With this new version you can now configure support for a custom form being used as default form.

Please read the topic "How to Configure Support for Messages with Non-Standard MAPI Identifiers" in the product documentation for more information about how to configure this feature. The example information in step 3.) applies to your case (IPM.Note.Default).
