Description
Mailward opens Outlook PST and OST archives, Outlook for Mac OLM exports, MBOX mailboxes (including Gmail Takeout) and EML/MSG messages directly in the browser. The file is parsed locally in a Web Worker and never uploaded, and there is no account for anything. Reading and search are free; batch export and opening a second archive side by side are a one-time $19 license. Works on Mac, Windows, Linux and ChromeOS without Outlook installed.
No-Login Task
"Open a PST, OST, OLM, MBOX or EML archive from your disk, browse its folders, read and search every message"
