XADM: Savechanges() Fails with MAPI_E_NOT_FOUND Error When Saving a Message with Custom Properties

• Microsoft Exchange Server, version 5.5

SYMPTOMS

The MAPI API IMessage::Savechanges() may fail with a MAPI_E_NOT_FOUND error when saving a message with custom properties whose property ranges are in the allowable ranges defined by the MAPI spec (0x6800 - 0x7FF).

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5.

MORE INFORMATION

This can occur when you attemp to "overload" property IDs by using several of the same property tag IDs with differing types. The Micrososft Information Store will not allow more than a single type per property tag in a single folder.

Because, internally, a folder contains both associated messages and normal messages in the same table, a situation can arise where two different property types are used for different types of messages. In this instance, the first to be written to the message will be the only allowable type in that folder (that is, Savechanges() will now fail if you attempt to use a different type for this property in future Savechanges calls).

Recognizing the occurence can be difficult (unless you are the software author). Treat this as a rare case.
