We'll break down the implementation into two main features: creating a reply message and forwarding a message using Aspose.Email for Java.

## How to parse MSG file Java and create a reply?

Load the original MSG, build a reply, and save it – all in three concise steps. First, instantiate a `MapiMessage` from the source file—`MapiMessage` represents an Outlook MSG email in Aspose.Email—then use `ReplyMessageBuilder` to set reply‑specific fields—`ReplyMessageBuilder` constructs a reply based on the original message—and finally call `save` to write the new MSG to disk. This pattern works for any MSG regardless of size and preserves original attachments and formatting.

## How to forward email Java using Aspose.Email?

Forwarding an email is as simple as loading the source MSG, configuring a `ForwardMessageBuilder`, and saving the result. `ForwardMessageBuilder` creates a forward message from an existing MSG. After loading, call `setForwardTo` with the new recipients—`setForwardTo` specifies the recipients for the forwarded email—optionally add a comment, then invoke `save`. The library automatically includes original attachments and preserves the message thread.
