Hi!


I am coding a solution that has a function to sync it's database with
Outlook. I use a User-Defined Field to keep track of "my" items and it works
great. BUT - I can not find a way to add the user-defined field to the
folder programmatically. If an app is to be distributet widely I can't ask
my users to do this by hand.

I have noticed that som apps (like Skype) has added user-defined fields
automatically, so there has to be a way - do you know or could you point me
in the right direction? I'm coding in C# and Visual Studio 2005.

Answered in Interop, although this is a better group for a question like
that.
 
If u want add fields to folder, u should create mailItem fill it with
properties and move to folder, that's all.

That would be totally ineffective. Moving an item to a folder has no effect whatsoever on the fields defined in that folder.

To define a field in a folder in versions before Outlook 2007, use the MAPIFolder.Items.Add method to create a new item in the folder (a post item if it's a mail/post folder). Then use the item's UserProperties.Add method to create the property on the item, setting the third parameter to True. Finally, delete this new item, which is no longer needed.
