Getting Well-Known Mailbox Folder URLs

Each user's mailbox folder has a set of properties that you can use to retrieve URLs for well-known subfolders such as Inbox, Calendar, Drafts, and Tasks. Additionally, you can retrieve the Microsoft® Exchange mail submission Uniform Resource Identifier (URI) that is used to send messages through WebDAV or the Exchange OLE DB (ExOLEDB) provider. The returned URLs are localized into the language that is used by the client.

The following table lists the properties that return these URLs and that are retrieved from a user's root mailbox folder.

PropertyWell-known folder (English)
urn:schemas:httpmail:calendarCalendar
urn:schemas:httpmail:contactsContacts
urn:schemas:httpmail:deleteditemsDeleted Items
urn:schemas:httpmail:draftsDrafts
urn:schemas:httpmail:inboxInbox
urn:schemas:httpmail:journalJournal
urn:schemas:httpmail:notesNotes
urn:schemas:httpmail:outboxOutbox
urn:schemas:httpmail:sentitemsSent Items
urn:schemas:httpmail:tasksTasks
urn:schemas:httpmail:sendmsgExchange Mail Submission URI
urn:schemas:httpmail:msgfolderrootMailbox folder (root)

To access these properties:

  1. Bind to the user's root mailbox folder. You can either request the server and username from the client to construct this initial URL or search Microsoft Active Directory® for the user's homeMDB attribute. From the value of this attribute, you can get the server on which the user's private mailbox is stored.
  2. Use the values of these properties to bind to these folders in a mailbox folder.
