How to Bulk Delete Emails in Outlook

Deleting emails one at a time is hopeless once you’re behind by thousands. Outlook has several ways to delete in bulk — the trick is picking the right one for what you’re trying to clear. Here are the fastest methods, from a whole folder down to a single sender’s history.

Method 1: Select all in a folder

To empty a folder (or a big chunk of one):

Open the folder and click any message.
Press Ctrl+A to select everything in view.
In Outlook.com / new Outlook, a bar appears offering to select all messages in the folder — click it to go beyond the visible page.
Press Delete.

Great for clearing a whole folder, but too blunt when you only want some of the mail gone.

Method 2: Delete by search

To bulk-delete a specific slice — one sender, a keyword, a date:

Search with a filter, e.g. from:noreply@example.com or a subject keyword.
Press Enter to list every match.
Ctrl+A to select all results, then Delete.

This is the workhorse method. The limitation: you have to run a separate search for each sender or term.

Method 3: Sweep (Outlook.com & new Outlook)

Sweep is built for recurring senders:

Select a message from the sender.
Click Sweep in the toolbar.
Choose Delete all from this sender — and optionally keep deleting future messages automatically.

Method 4: Delete by date

To clear everything before a certain date, sort by date or search a range and select all. Full steps: how to delete old emails in Outlook.

Where Outlook’s bulk tools run out

Every method above works on one folder, search, or sender at a time. A real cleanup usually means the same handful of senders across your whole mailbox — which turns into dozens of repeat searches. And Outlook never shows you which senders are worth targeting.

Sender Sweep closes that gap. It scans your entire mailbox, ranks every sender by volume, and lets you select many senders at once and delete all their mail in a single action — moved safely to Deleted Items, exactly like Outlook’s own delete. You can also filter to senders you never open, or delete only mail older than a date, before you clear it. Everything runs in your browser, so your email never leaves your device.

FAQ

How do I select more than one page of emails in Outlook? After Ctrl+A, Outlook.com shows a link to select all messages in the folder, not just the visible ones. Click it, then delete.

Do bulk-deleted emails get permanently removed? No — they go to Deleted Items and are recoverable for about 30 days. Empty that folder to reclaim space.

Can I bulk-delete from several senders at once? Not natively; Outlook works one search or sender at a time. Sender Sweep lets you select multiple senders and clear them in one pass.
