Exception converting .eml file to .msg file with certain ATTENDEE values

I'm using Aspose.Email to convert .eml files to .msg files. I've encountered a couple of cases where converting a meeting message with specific content (or lack thereof) will generate an exception. This is another instance separate from the others I've recently entered.

I'm using this code to do the conversion

MailMessage msg = MailMessage.Load("file.eml", MessageFormat.Eml);

msg.Save("file.msg",MailMessageSaveType.OutlookMessageFormat); <-generates exception

In this case, the text/calendar section contains this line;

ATTENDEE;SENT-BY="MAILTO:1234@emc.com";ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;RSVP=TRUE;CN=ES1TU 0000 04:MAILTO:ES1TU000004@customer.local

If I remove the part in red, the entry is converted successfully. Here's the entire text/calendar entry that causes the error.

Content-Type: text/calendar; charset="utf-8"; method=REQUEST
Content-Transfer-Encoding: 8bit

Hi Tom,


Could you please confirm to us if you copy the above text to a text file and save it in ICS format, are you able to open the resultant file? I was unable to open the file at my end in Outlook which makes it doubtful to work in Aspose as well. I would request you to please provide us the sample EML file so that we can reproduce the issue at our end and assist you further.

I saved it as a .ics and was able to open it in Outlook. I've attached the file (with a .txt extension since the forum won't let me upload .ics files).

Tom

Hi Tom,


Thank you for providing the ICS file.

I was able to observe this issue at my end using the latest version of Aspose.Email for .NET 2.8.0 and have logged it in our issue tracking system as NETWORKNET-33740 for further investigation by our development team. You’ll be notified here once the issue is resolved and fix version is available.

The issues you have found earlier (filed as NETWORKNET-33740) have been fixed in this update.
