Possible to load in an email in MSG file format, modify content of selected attachments, save back as MSG file?

GroupDocs.Total Product Family

As per subject, does any of the GroupDocs.Total components allow loading of MSG file, modification of attachments, and then saving back out as MSG?

Unfortunately, this feature is not currently supported by any GroupDocs products. We will consider adding it.

We will update you after discussing this feature with the team and completing our analysis.

Thanks, meanwhile, I don’t suppose it is possible to call the underlying Aspose.Email APIs directly to achieve this requirement?

@jarrodwee

Yes, there is no such option unless you have an Aspose.Email license to use the library.

The development team has analyzed this feature and planned to add it to GroupDocs.Conversion for .NET 25.3. It was decided to provide a callback function that you could implement to modify the contents of attachments when converting MSG to MSG.

As soon as the version is available, we’ll let you know.

Would GroupDocs.Conversion be able to also allow email metadata such as recipients, sent timestamp, etc, to be modified during the conversion from MSG to MSG process?

Perhaps GroupDocs.Metadata might be better suited to allow more extensive modification of MSG content, attachments and properties?

@jarrodwee

Taking into account that you also need to modify MSG content, attachments, and properties, it is reasonable to implement this feature within GroupDocs.Metadata, which already supports updating email fields.

Could you please clarify which set of fields you would like to update so I can pass your request along to the development team?

Besides the standard ones which are already available in GroupDocs.Metadata,
below are the fields of interest which I have yet to test if GroupDocs.Metadata is already able to access and update:

  • PR_INTERNET_MESSAGE_ID
  • Received Time
  • Sent On
  • BillingInformation

I believe it should also be possible to access/update custom X-Headers?

Separately, are there any known issues with Rich Text format emails in MSG which contain tables with attachments and images embedded in table cells?

@jarrodwee

Thanks for the details, we’ll analyze the requirements and update you.

Can you please provide the example MSG file that we could use to check for issues?
