This release includes an enhancement of saving messages from PST to Memory stream directly by enumerating MessageInfo or message Entry Ids. This was not supported with the earlier versions, as message extraction from PST files followed extraction of MessageInfo first and then retrieve complete message based on information from the MessageInfo objects. Adding Folder permissions to Exchange folders was supported by earlier versions of Aspose.Emial. But with this release, now Retrieving Folder permissions on Exchange Server are supported as well. This release also includes some important bug fixes. PST-to-PST and PST-to-OST message copying operations are more improved now. Various issues related to EML-to-MHTML and MSG-to-EML conversions have also been resolved in this release.
