Aspose.Email Product Family - Oct 20263 nov 2026
Aspose.Email for .NET V26.10Versión principal31 oct 2026
Funciones
  • Implemented Save and Load methods and added async support for MAPI items.
Correcciones
  • Incorrect loading VCF file version 4.0 to VCardContact with a value type single URI (Photo, Logo, Sound, Key).
  • FolderInfo.SetReadStatus throws KeyNotFoundException when the list holds only some of the folder's messages.
  • PersonalStorage.SplitInto keeps the last part file open and does not raise StorageProcessed for it.
  • PersonalStorage.MergeWith silently drops a nested folder when the source is a part written by SplitInto.
  • MboxrdStorageReader.GetTotalItemsCount() returns the number of remaining messages instead of the total.
  • MapiAttachment.ContentLength returns 0 for an embedded message attachment.
  • MapiRecipientCollection.Add(address, displayName, recipientType) sets AddressType to UNKNOWN for SMTP addresses.
  • VCardContact.Save throws NullReferenceException for an ExtendedProperties item without ':'.
  • VCard 2.1/3.0: CHARSET parameter added to binary PHOTO and VCard 4.0: PHOTO written as 3.0.
  • MapiContact: GENDER and X- properties from vCard are not imported; Gender is written as X-GENDER:Male instead of GENDER:M in vCard 4.0.
  • MessageValidator.Validate returns IsSuccess False and errors.
  • VCardContact.Load does not populate IdentificationInfo.Anniversary.
Aspose.Email for C++ V26.10Versión principal31 oct 2026
Funciones
  • Support for RFC Message file format detection - Files that are not standard EML or MHT formats are now correctly identified as RFC messages, allowing broader compatibility when processing email files. The detection uses the new FileFormatType::RfcMessage enum value.
  • TgzReader GetItemsCount method for item type quantities - A new method enables you to retrieve the count of specific item types within a TGZ archive, simplifying content analysis. This addition works alongside the ItemType enumeration for clear type specification.
  • Adding Attachments from a Stream or a File:
    • Previously, adding binary content to a MapiMessage required a byte array, so the entire attachment had to be held in memory before it could be added. Attachment content can now be supplied as a stream or taken directly from a file, and it is read on demand instead of being copied into memory.
    • New Methods and Properties:
      • System::SharedPtr<MapiAttachment> MapiAttachmentCollection::Add(System::String name, System::SharedPtr<System::IO::Stream> content) Adds an attachment whose content is read from the stream. Content is taken from the stream's current position to its end, and the range is fixed at the moment of the call.
      • System::SharedPtr<MapiAttachment> MapiAttachmentCollection::Add(System::String name, System::SharedPtr<System::IO::Stream> content, bool leaveStreamOpen) Same, with explicit ownership of the stream. When leaveStreamOpen is false, the stream is disposed together with the message.
      • System::SharedPtr<MapiAttachment> MapiAttachmentCollection::AddFile(System::String filePath) Adds an attachment reading its content from a file, using the file name as the display name.
      • System::SharedPtr<MapiAttachment> MapiAttachmentCollection::AddFile(System::String filePath, System::String displayName) Same, with an explicit display name.
      • System::SharedPtr<System::IO::Stream> MapiAttachment::OpenRead() Returns an independent, read-only, seekable stream over the attachment content. Each call returns a separate reader, so several readers can be used at the same time.
      • int64_t MapiAttachment::get_ContentLength() The length of the attachment content in bytes, available without reading the content.
  • Deferred Attachment Content Loading:
    • By default, MapiMessage::Load reads the content of every attachment into memory together with the message. For messages with large attachments this makes the memory required to open a message proportional to the size of its attachments, even when only the headers, the recipients or the attachment names are needed.
    • Attachment content can now be left in the source and read on demand.
    • New Properties:
      • bool MsgLoadOptions::get_DeferAttachmentContent() / void MsgLoadOptions::set_DeferAttachmentContent(bool value) When true, attachment content is read from the source on demand instead of being loaded with the message. The default is false, so existing behavior is unchanged.
      • int32_t MsgLoadOptions::get_DeferralThreshold() / void MsgLoadOptions::set_DeferralThreshold(int32_t value) The minimum content size, in bytes, for which deferred loading applies. Attachments smaller than this are always loaded eagerly. The default is 4096.
