MailBee.NET Outlook Converter

MailBee.NET Outlook Converter is an easy-to-use .NET component which allows your application to convert e-mails between .MSG and .EML formats and read .PST files in a few lines of code. Backed with commercial-grade support.

You can also read .PST, .MSG and .EML data from streams or convert between .MSG data and MailBee.Mime.MailMessage objects.

.MSG format is supported by MS Office Outlook. It's one of Microsoft's binary formats based on OLE2 document specification.

.PST is the format of an Outlook mailbox file. It stores all the folders with all the messages, contacts, appointments and tasks of a particular Outlook user.

.EML format (also known as RFC822 and MIME) is the most popular for storing and exchanging e-mails across various systems.

However, no knowledge of .MSG, .PST and .EML formats is required in order to use this component.

Written in 100% managed code, this component only requires the .NET framework be installed on the computer.
