Setting custom properties to an outlook folder

[Michael Jennings]

Hi,
I'm new to the Outlook 2007 object model. I want to create and set some
custom properties to my outlook folders. eg I want to set a property like
'SOURCE URL', which is of string type, that will enable me to find out
programmatically which folder belongs to which url. I think PropertyAccessor
has something to do with it. But I don't know how to use it. In what format
the property name should be given?
It throws an exception that 'Unable to parse the property name'.

Please post the relevant portion of the code you already have in the microsoft.public.outlook.program_vba newsgroup, which handles programming issues.

For custom properties, Microsoft recommends using the MAPI string namespace, which uses this syntax for the property name, which is always a string:

"http://schemas.microsoft.com/mapi/string/{HHHHHHHH-HHHH-HHHH-HHHH-HHHHHHHHHHHH}/name"

where {HHHHHHHH-HHHH-HHHH-HHHH-HHHHHHHHHHHH} is a GUID (globally unique ID) and name is the property name itself. Developers of Outlook add-ins should use the GUID for their application as the GUID for the property.

I've set my property name as:-
"http://schemas.microsoft.com/mapi/string/{5ae18700-583b-4e33-b0b8-bbcffc9ebd24}/siteUrl"

It throws an exception :-

The property
"http://schemas.microsoft.com/mapi/string/{5ae18700-583b-4e33-b0b8-bbcffc9ebd24}/siteUrl" does not support this operation.

when I invoke SetProperty(). This is my code below:-

string prop =
"http://schemas.microsoft.com/mapi/string/{5ae18700-583b-4e33-b0b8-bbcffc9ebd24}/siteUrl";
Folder folder = (Folder)tasksFolder.Folders.Add(folderName,
OlDefaultFolders.olFolderTasks);
folder.PropertyAccessor.SetProperty(prop, "http://www.microsoft.com");

-Thanks

Ah, I forgot that you can't create custom properties on a folder, only read MAPI properties with PropertyAccessor. Instead, create a new StorageItem in a mail/post folder and use that to hold your application information.
