Description
Free up Outlook.com and OneDrive storage: find and delete large attachments, files, and duplicates. Runs entirely on your device. See exactly what's filling your Microsoft storage, and free up space across Outlook and OneDrive, without your emails or files ever leaving your device. Scan locally. Review first. Clean up only what you approve. Sound familiar? • "Your storage is full" warnings that won't go away • Can't send or receive email because storage is over quota • Deleted hundreds of emails but storage still shows full • OneDrive says it's full and you don't know what's using the space Storage Cleaner scans your Outlook mailbox, your OneDrive, and your Microsoft storage quota, then ranks cleanup opportunities by how much space they can free. Everything runs in your own browser, on your device. Your emails and files are not uploaded to our servers. Why deleting emails often doesn't help: Outlook attachments count toward the same Microsoft storage quota as OneDrive, and deleted items keep using space in Deleted Items and the recycle bin until they are emptied. Storage Cleaner finds all of it. 🔎 WHAT IT FINDS 📧 Outlook Find large attachments, old mail with attachments, drafts with attachments, promotions and social mail, junk email, and Deleted Items. ☁️ OneDrive Find large files, large videos, photos and screenshots, duplicate files, old file versions, and the recycle bin. ⚙️ CLEAN AT YOUR OWN PACE Choose how deep to scan: • Quick: older than 6 months • Standard: older than 3 months • Deep: any age You can also set your own age floor: no minimum, older than 3 months, older than 6 months, or older than 1 year. ✅ YOU STAY IN CONTROL • Nothing is moved or deleted without your review and approval • Flagged and high-importance mail is always excluded • Add protected keywords, and matching items are skipped • Protect specific senders so their mail is never touched • Files with personal-looking names are highlighted and left unchecked • Reversible cleanups move items to Deleted Items or the OneDrive recycle bin first, restorable for up to 30 days • Permanent actions, like emptying Deleted Items or removing old file versions, are clearly labeled before you confirm 🔒 PRIVATE BY DESIGN • Runs in your browser, on your device • Requests go directly between your browser and Microsoft • Your emails and files are not uploaded to our servers • No new account is required • You can revoke Microsoft access anytime The scan is free.
