New: export any email as PDF or Word in one click. Open Outlook PST, OST, MSG, EML, EMLX and MBOX files on your Mac — no Outlook required. Fast, offline, private. OldMail opens the email files you've been keeping for years — and turns them into documents you can actually use. Outlook archives, single messages, whole mailboxes: they all open on your Mac in seconds, with no Outlook, no mail account and no internet connection. SUPPORTED FILES • PST and OST — Outlook archive and offline data files, opened by a native parser built for macOS. Browse the original folder tree and read any message inside. • MSG — Outlook messages, including attachments. • EML — the standard email format used by Apple Mail, Thunderbird, Gmail exports and most mail servers. • EMLX — Apple Mail's single-message files. • MBOX — mailbox files from Thunderbird, Google Takeout and other exports, plus Apple Mail .mbox packages. • Whole folders — point OldMail at a folder of EML, EMLX or MSG files and every message is listed in a single tab, subfolders included. EXPORT AS PDF OR WORD • Turn the email you're reading into a clean PDF or Word document with one click, or press ⇧⌘E. • Subject, sender, recipients and date are laid out at the top, followed by the message exactly as you see it — formatting and inline images included. • Attachment names and file types are listed right under the subject, so nothing is lost while the document stays small and easy to email, archive or print. • Pick PDF or Word from the dropdown next to the button; your choice is remembered. SAVE AND FORWARD • Save any message as a file, including messages that live inside a PST, OST or MBOX. • Forward a message as an attachment through your default mail app — or choose which installed mail app to use. • Open attachments in the app of your choice, or save them anywhere on your Mac. BUILT FOR LARGE ARCHIVES • Messages appear in the list while indexing is still running, so you can start reading immediately instead of watching an empty window. • Large PST files are read straight from disk rather than loaded into memory, and message lists are built from headers only — fast even with thousands of messages. • Temporary files are reused and cleaned up automatically, so OldMail doesn't quietly fill your disk. A READER THAT FEELS LIKE HOME • Browser-style tabs: keep several files, archives and folders open side by side. • Pin a tab and that file opens automatically the next time you launch the app. • HTML emails are rendered with their original styling and inline images; plain text stays plain. • Search within any message list by sender or subject. • Resizable columns, full Dark Mode support, and a searchable history of everything you've opened. • Folders stay live: add or remove a message on disk and the list updates instantly. EASY TO OPEN ANYTHING • Use the Open button (⌘O), or simply drag and drop files onto the window. • Make OldMail your default viewer so double-clicking a mail file just works. PRIVATE BY DESIGN Everything happens on your Mac. OldMail has no accounts, no sync, no tracking and no ads, and it never uploads your messages anywhere. Your archives stay exactly where you put them. Available in English and Turkish.

Turn any email into a PDF or Word document — and open even more mail formats. NEW: Export as PDF or Word • The new "Export as" button turns the email you're reading into a polished PDF or Word document, complete with subject, sender, recipients and date. • Choose your format from the dropdown next to the button — PDF or Word — and OldMail remembers it for next time. ⇧⌘E exports in one step. • Attachment names and file types are listed right under the subject, so you keep the full picture while the document stays small and easy to share. The attachments themselves are never embedded. • Export works everywhere: single EML, EMLX and MSG files, messages inside OST and PST archives, MBOX mailboxes, and whole email folders. NEW: EMLX and MBOX support • .EMLX — Apple Mail's single-message files now open just like EML and MSG, and they appear in folder views too. • .MBOX — mailbox files from Thunderbird, Google Takeout and other mail exports, as well as Apple Mail .mbox packages, open in their own tab with a message list and reading pane. Much faster with large archives and folders • Messages now appear as they are indexed. No more waiting in front of an empty window while a large PST or a folder with thousands of emails is read — a progress strip shows how many messages have been indexed, and you can open any message that has already arrived in the list. • Message lists are now built from message headers only, which makes indexing several times faster — dramatically faster for emails with large attachments — and far lighter on memory. Less disk space used • Temporary copies created when you open an attachment or forward a message are now reused instead of duplicated, and are cleaned up automatically at launch, freeing space that used to build up over time. Also fixed • Opening a second archive, folder or mailbox tab could leave its message list empty until you switched tabs. • Various stability improvements.
