Delete Messages from PST File Permanently & Enhanced EML to MSG Conversion inside .NET Apps

Aspose team is pleased to announce the release of Aspose.Email for .NET 17.4.0. This month’s release comes with several enhancements related to Outlook messages and Storage files i.e. PST/OST. Aspose team has also fixed a number of bugs that further improves the overall functionality and stability of the API in terms of expected output. Consider a scenario where users are given a PST file and a set of messages that have been designated as attorney-client privileged. Given a list of entry IDs for those privileged messages, users are supposed to remove those messages and forward the PST to opposing legal counsel. If the deleted messages are recoverable by forensic tools, this defeats the purpose. To help users about this, Aspose team is glad to share that this month’s release enhances the functionality of deleting messages from a PST file permanently. This means these are no more recoverable from the PST file with recovery tools. There is no public API change that users need to incorporate in their code to achieve this. Users existing code sample for deleting messages from PST file will do the job with this latest release of the API. This month’s release also provides support for a new Mapi property i.e. PT_FLOAT. The API already supports other properties as well and the addition of this new one further enhances the list of such propertie. Following code sample shows how to add such type of MAPI property to an Outlook message. In addition to the enhancements mentioned above, this month’s release also includes several bug fixes for the issues reported by API users. Details about these can be found in release notes section of our documentation. The main bug fixes & improved features added in this release are listed below
