Meeting Invitation Mails' Flag Issue

[bvrakvs]

Flagged meeting invitation mails and conversations of those mails return with NotFlagged status. (getFlagStatus) I guess this is some kind of a bug. Can you resolve the issue?

I can't check directly at the moment, but it seems that this is probably due to the FlagStatus not being correctly loaded from the XML of the response. The method to retrieve it in Conversation will return ConversationFlagStatus.NotFlagged if the property isn't present, but a check of the code involved doesn't bring up any obvious causes as to why the property isn't being loaded. The XmlElementName and FieldUri for the property appear correct. Can you attach a TraceListener to the ExchangeService and take a look in the XML when running a FindConversation operation to see if the FlagStatus element is present? Also, are you aware of any other properties that are not being correctly loaded in Conversation?

EDIT: I don't have access to a server at the moment, but I was able to run a quick and dirty test locally with some XML. FlagStatus is correctly read from the response and is listed as a first class summary property in the API, but that doesn't seem to match the documentation, at least not from what I've been able to see. If you use a custom property set with FlagStatus in it for the FindConversation operation or use Conversation.load() with said custom property set, do you get the correct FlagStatus?

On a related note, is there a good source to check on which properties throughout the API are first class properties? I can find bits and pieces in the online documentation, but a comprehensive list would be nice.
