Convert MSG to Different Formats

The Java Email API provides easy-to-use interfaces for the conversion of supported message file formats. In order to perform a conversion, all you need to do is to load the source file in Aspose.Email object model and call the save method with appropriate parameters. It is really that simple!

Save message in different formats - Java

// load the file to be converted
MailMessage message;
message = MailMessage.load(dir + "template.msg");
// save in different formats + "output.eml", SaveOptions.getDefaultEml()); + "output.html", SaveOptions.getDefaultHtml()); + "output.mhtml", SaveOptions.getDefaultMhtml());

Calendar Objects Management

Aspose.Email for Java provides you the capability to create and save Outlook Calendar objects through its iCalendar API. Not only you can extract the Calendar objects in various formats and save them as MSG or ICS files but you can also send, retrieve, update and cancel meeting requests through message sending protocols.

Emailing via SMTP, POP3 & IMAP

Aspose.Email for Java empowers to create complex email messages with attachments, HTML formatting and images, and send them to an email address using SMTP protocol. It also allows you to log onto the POP3 servers via username & password or APOP authentication to perform operations like view mailbox size & message count, retrieve the full message or just the headers, delete messages from server and so on. It also supports IMAP protocol features including authentication, create, delete, select, query folders, get and save messages and change message flags.

Manage Message Storage Files

Aspose.Email for Java allows you to manage Outlook storage files. You can load PST & OST files from disk or a stream, get folder and sub-folder information from the message archive, retrieve message specific details such as subject, sender, recipient and save messages to either disk or stream.

Apart from parsing an existing PST, Aspose.Email for Java also provides the means to create a PST file from scratch and messages to any folder of it.

Create PST from scratch & add message from file - Java

// create an instance of PersonalStorage
PersonalStorage pst = PersonalStorage.create(dir + "archive.pst", 0);
// create a folder at the root of PST
// add message to newly created folder
pst.getRootFolder().getSubFolder("Inbox").addMessage(MapiMessage.fromFile(dir + "template.msg"));

Microsoft Office Automation – Not Needed

Aspose.Email for Java is built using managed code that does not need Microsoft Office or Microsoft Outlook to be installed on the machine to work with emails processing. It is a perfect Microsoft Outlook automation alternative in terms of supported features, security, stability, scalability, speed and price.
