The .pst from a retired PC, the orphaned .ost from a job that ended — drop it here and get every email back out, readable anywhere. Free, no signup, nothing retained.
A ZIP mirroring your folder structure — Inbox, Sent Items, everything. As EML, each message is its own file that opens in Apple Mail, Thunderbird, Outlook or any text editor, attachments included inside the message. As MBOX, you get one importable mailbox file per folder — in Thunderbird, right-click a folder and use ImportExportTools NG. Contacts come out as vCards and calendars as .ics along the way.
Yes — and that matters, because Outlook itself can’t reopen an orphaned .ost once the account it belonged to is gone. If all that survives of an old mailbox is the offline cache from a machine backup, this reads it directly. No Exchange server, no “convert OST to PST” shareware.
Usually fine. An Outlook PST password only gates Outlook’s own user interface — the messages inside are not encrypted with it. The extraction engine (libpst) reads the data directly, so a forgotten password on your own old archive is not the end of the story.
Both PST generations: ANSI (Outlook 97–2002) and Unicode (2003 onward), plus their OST counterparts. Files up to 100 MB — bigger archives exist; tell us if you have one and we’ll see what we can do.
It’s written to a private temporary folder for the few seconds the conversion engine needs, then deleted — nothing is retained, logged or shared. No account, no email, no “files kept for 24 hours” fine print. These are often someone’s letters, family records or old business files; we treat them accordingly.
