I agree about the table formatting issue. I will forward it to Aspose.Words.
About the date formatting:
In order to reproduce it you need to have regional settings changed to different language: Bulgarian in my case.
In the attached zip you can see “paypal_6_1_formatting_ByOutlook.mht” file, which is produced by Outlook 2013 on my machine.
Outlook output - encoded:
<…mso-ansi-language:BG’>май 2013 г. 22:50…>
And Aspose output - not encoded:
<span class=3D’headerLineText’>??? 2=2E5=2E2013 ?=2E 22:49
Interesting is also that Aspose.Email 6.1 converts other files just fine. For example the attached “DropBox.eml” is converted to “DropBox.eml.1.MHtml” and the date is fine there:
<span class=3D’headerLineText’>=D0=BF=D0=B5=D1=82 6=2E12=2E2013 =D0=B3=2E 20:09
That is why I think the problem is in Aspose.Email 6.1 and affects only specific files.
