How to Clean Outlook's Other Tab and Focused Inbox (Clear Thousands of Emails)
The Other tab fills faster than you can delete. Here's how to clear it permanently — not just temporarily.
What is the Outlook Focused/Other split?
Outlook introduced Focused Inbox in 2016, automatically splitting incoming mail into two tabs: Focused for personal and important messages, and Other for newsletters, marketing emails, and bulk mail. There is no separate Promotions tab — Other does that job, plus a few more.
Focused
Personal and important messages that Outlook thinks you actually want to see.
Other
Newsletters, marketing, deals, social notifications, and most automated mail.
Junk Email
Spam and phishing that Outlook auto-filters. Auto-emptied after 30 days.
Why the Other tab never clears
Deleting emails from the Other tab does not stop those senders from emailing you again. Each sender you have ever given your email address to keeps sending — often daily. The Other tab refills because the underlying subscriptions remain active.
You're still subscribed
Deleting an email removes it from your mailbox. It does not unsubscribe you. The same sender will land in Other again tomorrow.
Purchase history triggers new senders
Every time you buy something online, the retailer — and their partners — may add you to new mailing lists.
Outlook's classifier shifts
As Outlook's Focused/Other classifier learns, emails that previously landed in Focused can be retroactively moved to Other, and vice versa.
Accounts shared or sold
Some companies sell or share customer email lists. Your address can end up subscribed to senders you never interacted with.
Manual cleanup methods
Option A: Select all and delete
Option B: Use Sweep on noisy senders
Right-click any email in the Other tab and choose Sweep. Outlook offers four options: Delete all messages from the Inbox folder, Delete all and any future messages, Always keep latest message and delete the rest, and Always delete messages older than 10 days. The third and fourth options run continuously — set them once, they keep working.
Option C: Create an inbox rule
Go to Settings → Mail → Rules → Add new rule. Match by Subject, From, or Importance, then choose an action: Delete, Move to folder, or Mark as read. Rules apply to future mail only and run on the server, so they work even when Outlook is closed.

Frequently asked questions
How do I empty the Other tab in Outlook all at once?
In Outlook, click the Other tab next to Focused. Click the first item, scroll to the bottom, hold Shift, and click the last item — every item in between is selected. Press Delete (or click the trash icon). All Other-tab items move to Deleted Items. Note: this empties the existing backlog; it does not stop new emails from being routed to Other.
Why does my Outlook Other tab keep filling up even after I clear it?
Outlook's Focused/Other classifier routes incoming promotional and bulk mail to Other regardless of how many times you empty it. The only way to permanently reduce volume is to unsubscribe from those senders or run Sweep on them. Deleting emails does not unsubscribe you.
Can I turn off the Focused/Other split in Outlook?
Yes — in Outlook for Web, go to Settings (gear icon) > Mail > Layout > Focused Inbox and choose "Don't sort messages". In Outlook desktop, View > Show Focused Inbox toggles it off. Promotional emails will then arrive in your main inbox. This does not reduce volume — it just changes where they land.
Is it safe to delete everything in the Outlook Other tab?
For most users, yes — Outlook's Focused/Other classifier is accurate at separating bulk mail from personal mail. However, some legitimate emails (order confirmations, flight bookings, event tickets) can land in Other. Review before bulk-deleting, or use a tool like Gorganizer that automatically protects receipts and attachments before removing anything.
What is Outlook's Sweep function?
Sweep is Outlook's bulk-cleanup action. Right-click any email and choose Sweep — you can delete all emails from that sender, move them to a folder, or schedule a recurring cleanup (e.g. always delete emails from this sender older than 10 days). Sweep applies retroactively AND to future emails.
