I am trying to access the "To"-Field in the mail header while hooking into the UploadOperation of an email item in the Harmon.ie Outlook addin (to rename the file using some defaults when uploading to sharepoint).
For some reason the only header fields I get from the uploaded item are Received, Date and From.
What I currently do is iterating the IUploadItemData elements in the IWrappedList inside the onBeforeUpload handler.
Then checking for items of type IUploadMailItemData and trying to access their MetaDataValue fields using the Harmonie.SDK.MailHeader class constants as keys. But as already mentioned I only get the 3 fields Received, Date and From.
What am I doing wrong? May I load the other header fields somehow too?
