Property Value

Type: String
A string containing a positive 64-bit number, or a null reference (Nothing in Visual Basic) in case if this value is not available (usually, if the server is not Gmail or GmailThreadID was not requested when downloading envelopes).
Gmail provides a thread ID to associate groups of messages in the same manner as in the Gmail web interface. To use this value, make sure the mail server is Gmail-compatible ("x-gm-ext-1" capability must be listed in GetExtensions results).
