Hi,

We use Aspose network to convert eml to msg which works fine. Another department of the company now needs to convert the file back again to eml and they receive an exception, below you find the exception message.

What could cause this exception?

Exception.Message: Invalid character at position 3.

Parameter name: name

Exception.Source: Aspose.Network

Hi Malin,

Thanks for considering Aspose.

Please try the latest version of Aspose.Network. I tested the attached msg file, there was no exception, but still the body of eml was coming blank. The code used was:

MailMessage msg = MailMessage.Load(@"EUROPE_FIF00358_MOTSWE_cb4c8dc5-bc69-447a-921c-9209b7d407a7.msg", MessageFormat.Msg);

msg.Save(@"test.eml", MessageFormat.Eml);

Please let us know your results with the latest dll. We will look into the problem and get back to you soon.

Hi,

Could you also post the source eml file here, which was converted to the above attached msg? We want to check the conversion process (eml --> msg and msg --> eml) using the original eml file.

Hi again,

The hotfix did work, we got an error message when we try to convert the eml file to msg, the error message is: "An invalid character was found in the mail header." And we found as well another issue regarding the attachment when we convert form msg to eml. The attachment file name has swedish charator maybe this could cause another problem.

Please take a look at that as well.

Kind Regards,
