How to get user's MaximunAttachmentSize value in Outlook VSTO.

Outlook gives a warning when the user adds the file with drag and drop, but when he sends the mail, the mail does not go.

What I want to do is to show the message box if the added file size is larger than outlook MaximunAttachmentSize.
