Mailbox full? Mail Vault for Outlook gets your space back - without losing a single email. Mail Vault moves older email out of your mailbox and into a "vault" on your own PC, USB drive or network drive. Every email is copied, saved as a standard file and fingerprint-checked before anything is removed from your mailbox. Your old mail stays one search away, and you stay in control the whole time. SAFE BY DESIGN Nothing leaves your mailbox until its copy has been saved and verified with a SHA-256 fingerprint. If a copy can't be verified, the original simply stays where it is. Before anything changes, you see a plain-English preview of exactly what will happen. When a run finishes, you get a Vault Receipt that says what was moved, how much space was freed, and confirms every email was verified. SEE WHERE YOUR SPACE GOES A live Space Gauge shows how full your mailbox is and warns you at 75%. The Storage Forecast looks at how fast your mail is growing and estimates when you'll run out of room. The interactive Mailbox Map shows your mailbox as tiles by folder, sender, year or attachment type. Tap any tile to archive it. ONE-TAP CLEAN-UPS - Time Capsule: drag a slider to "keep the last 12 months in Outlook" and see how much space you'll free, live. - Senders: sweep newsletters and notification emails in one go. - Big emails: move messages with large attachments. Flagged emails stay in Outlook unless you say otherwise. FIND ANYTHING, INSTANTLY Search every vault at once by words, sender, date or attachment. Emails open in a safe reader where scripts never run and remote images stay blocked until you allow them. Need something back? Send any email back to Outlook as a normal received message, with its original date. NO LOCK-IN Your mail is stored as standard .eml files that almost any email app can open. A vault is just a folder, so you can copy it to another drive or PC and it keeps working. Every vault also includes an "Open Me.html" page that lets you browse and search it in any web browser, even on a computer without Mail Vault. PRIVATE Mail Vault has no servers and collects no data. Your email travels only between Microsoft's mail service and the folder you choose. Your sign-in is encrypted by Windows and stored only on your PC. BUILT FOR REAL LIFE Pause any time and pick up where you left off. If your PC sleeps, the app closes or a USB drive is unplugged, nothing is lost. Just press Resume. Prefer to only make copies? Turn on Copy Only mode, and Mail Vault will never remove anything from your mailbox. Works with Outlook: the new Outlook for Windows, classic Outlook, Outlook on the web, Outlook.com, Hotmail and Microsoft 365 work or school accounts. Try it first with the built-in demo mailbox. No sign-in needed.
