The Outlook cleaner that goes beyond Sweep
Outlook's built-in Sweep is genuinely useful — one sender at a time. ClearInbox connects to Outlook and Microsoft 365 through Microsoft Graph and applies sweep-style cleanup to your whole mailbox at once: bulk delete by category, age and size, one-click unsubscribe for every newsletter, and rules that keep the Focused and Other tabs both under control.
Everything Sweep does, configured in bulk
Sweep's best tricks — delete all from a sender, keep only the latest message, delete mail older than a threshold — become bulk operations in ClearInbox. Select fifty noisy senders in one screen and apply keep-newest or delete-after-days to all of them in one action, instead of configuring them one dialog at a time.
Bulk delete Outlook emails by what they are
Smart folders group your Outlook mail into newsletters, notifications, social, finance, old and large messages. Archive or delete whole categories in one sweep, with every action logged and reversible via Deleted Items.
One dashboard for Outlook, Gmail and IMAP
Most people do not live in one mailbox. Connect a work Microsoft 365 account and a personal Gmail and clean both with the same smart folders, the same rules and the same screener — something neither provider's built-in tools can do.
Frequently asked questions
How is this different from Outlook's built-in Sweep?
Sweep works one sender at a time. ClearInbox shows every sender and category at once, applies sweep-style rules (keep newest, delete after days) in bulk, adds one-click unsubscribe, and runs the same cleanup across your other mailboxes too.
Does it work with Microsoft 365 work accounts?
Yes — Outlook.com, Hotmail and Microsoft 365 accounts connect over Microsoft Graph with OAuth. If your organization restricts third-party apps, your admin may need to approve access.
Can I recover mail after a bulk delete in Outlook?
Yes. Deleted mail goes to Deleted Items first, and Outlook keeps a recover-deleted-items window even after that folder is emptied. ClearInbox logs every bulk action so you know exactly what was removed.
