Storage Cleaner for Outlook.com, Hotmail & OneDrive - Bulk Delete

See exactly what's filling your Microsoft storage, then free up space across Outlook.com and OneDrive: delete what you won't miss, or keep what matters by moving it to another Microsoft account you already own. Your emails and files never leave your device.

Scan locally. Review first. Nothing is removed until you approve it.

Works with personal Microsoft accounts: Outlook.com, Hotmail, Live, and MSN addresses, and the OneDrive that comes with them.

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 • Big files and old attachments you'd rather keep, but nowhere to put them

Storage Cleaner scans your Outlook.com mailbox, your OneDrive, and your Microsoft storage quota, then ranks what it finds by how much space each step 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.com 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.com Large attachments, old mail with attachments, drafts with attachments, newsletters and promotions in your Other inbox, junk email, and Deleted Items.

☁️ OneDrive Large files, large videos, photos and screenshots, duplicate files, old file versions, and the recycle bin.

The dashboard starts you with a few safe, reversible cleanups, then shows the bigger items that need your call.

📦 KEEP IT, MOVE IT

Not everything taking up space deserves to be deleted. Move large files, videos, photos, and emails to another Microsoft account you already own, without downloading and re-uploading them yourself.

• Files are copied to the other account and verified against Microsoft's own checksums before the original moves to the recycle bin here • The new folder is shared back to this account, so your files stay findable from your own OneDrive search • Emails are saved as files in the other account's OneDrive, the attachments as files plus the email itself, which OneDrive opens like an email. They are shared back to you as files, not returned to your inbox • Nothing is removed here until every file arrives safely, and one tap puts everything back • Connect up to three accounts you own. Every free Microsoft account includes 5 GB, so with three connected you go from 5 GB to up to 20 GB combined • Don't have another account? Microsoft lets you create one for free at outlook.com. One sign-in every two years keeps it active

⚙️ CLEAN AT YOUR OWN PACE

✅ 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, with one-tap Undo • Permanent actions, like emptying Deleted Items or removing old file versions, are clearly labeled before you confirm • Clean more than one Microsoft account: an old Outlook.com or Hotmail address has its own storage to recover

🔒 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
