Msg send internally will not convert to eml

L.S.,

Below code is used to convert .msg files to .eml files. This works fine, nothing wrong with this…

But, every now and then a System.NullRefferenceException error returns when converting a .msg file.

Attached a zip file with 2 .msg files. 1 converts 2 .eml fine with below function and the other doesn’t.

I think I’ve found the difference between the two .msg files:

  • one .msg is send externally (sending mail server is the same as the receiving server)

  • one .msg is send internally (never ‘left’ the exchange server)

Are these findings correct and why does the MailMessage object have a problem with the internally send msg file?

How can I convert the internally send .msg file to .eml?

Public Function ConvertMsg2Eml(ByVal sMsgFileName As String) As Boolean
    Try
        SetAsposeLicense()
        'Load mail message
        Dim message As MailMessage = New MailMessage
        message = MailMessage.Load(sMsgFileName, MessageFormat.Msg)
        'Save to msg file
        message.Save(Replace(sMsgFileName, ".msg", ".eml"), MailMessageSaveType.EmlFormat)
        ConvertMsg2Eml = True
    Catch ex As Exception
        ConvertMsg2Eml = False
    End Try
End Function

Hi Erik,


Thanks for writing to Aspose.Email support team.

I have analyzed the information and this issue is re-produced using your sample msg files here.

I also tried with some other sample messages as well, having similar nature i.e. sent from SMTP to Exchange and sent from Exchange to Exchange however this issue was not observed with these messages.

I have passed this whole information and sample messages to the development team, and will write back here as soon as some feedback is received from the development team.

This issue is logged in our issue tracking system as NETWORKNET-33613.
