Convert your Apple Mail EMLX files to Outlook PST format. No Outlook installation required for conversion.
Apple Mail stores emails as individual EMLX files — a proprietary format that only Apple Mail can read. Outlook expects PST files. There is no built-in path between the two.
MailtoPst converts EMLX to PST directly, without any intermediate format. Upload your Apple Mail files, get a clean PST that Outlook imports without issues.
Open Finder, press Cmd+Shift+G, type ~/Library/Mail/. Navigate to find your .emlx files inside the mailbox folders.
Select the mailbox folders you want to migrate, right-click and Compress, then upload the ZIP to MailtoPst.
MailtoPst processes all EMLX files and generates a single PST with your complete folder hierarchy preserved.
Open the PST file in Outlook via File > Open & Export. Your Apple Mail emails, attachments, and folders appear instantly.

First conversion free. No credit card required.
