I'm developing a VSTO addin and I'm coming to the part where I'm
checking if a particular folder exists:

Dim oTweetFolder As Outlook.MAPIFolder = ReadDefaultFolders.Folders("@"
& m_twConn.AccountInformation.ScreenName)
'first run so we'll dynamically create the folders
If oTweetFolder Is Nothing Then


But I keep getting a A first chance exception of type
'System.Runtime.InteropServices.COMException' on that first line. Is
there any other way to check the existance of a folder without
triggering an exception?
