PRB: Can't Set Named Properties on a Folder in Exchange Info Store

• Microsoft Exchange Server, versions 5.0, 5.0 SP1, 5.0 SP2, 5.5
• Exchange Development Kit (EDK), versions 5.0, 5.5

SYMPTOMS

Attempting to add a named property to a Microsoft Exchange Server folder located in the private Information Store returns the following error message:

MAPI_E_NO_SUPPORT (80040102)

CAUSE

Exchange Server Information Store does not support named properties on folders.

STATUS

This behavior is by design.

MORE INFORMATION

Microsoft Exchange Server supports only predefined MAPI properties on folders. You cannot add or define custom named properties on Microsoft Exchange Server folders. Named folder properties are supported by the Personal Store (PST). Other servers may support named properties on folders. A workaround is to make a hidden message in the folder and then set the named properties on the hidden message.

REFERENCES

For more information on named properties please refer to Microsoft Developer Network and search for "Named Properties".
