Understanding Thunderbird EML and MS Outlook PST Formats:

To better understand the issue at hand, let's first clarify the difference between Thunderbird EML and MS Outlook PST file formats.

Thunderbird, the email client developed by Mozilla, stores emails in the EML (Electronic Mail) format. Each EML file represents a single email message and contains the message's header, body, attachments, and other relevant data.

On the other hand, MS Outlook, developed by Microsoft, uses the PST (Personal Storage Table) format to store email messages, calendar items, contacts, and other data. A PST file can contain multiple folders, such as Inbox, Sent Items, and Drafts, making it a more comprehensive storage solution for Outlook users.

Reasons for Incompatibility:

The incompatibility between Thunderbird EML and MS Outlook PST formats arises due to the differences in their underlying structures. Thunderbird's EML format is not directly compatible with MS Outlook's PST format, resulting in an error when trying to open EML files in Outlook.
