Outlook Not Receiving Emails? 8 Fixes to Try

"They say they sent it but I haven't got it." It's one of the most common calls I get. The good news is that in nearly every case the email has arrived — it's just not where you're looking — or there's a simple setting switched the wrong way. Work through these in order.

If Focused Inbox is on, your inbox has two tabs: Focused and Other. Click Other — that's where most "missing" emails are. Then open the Junk Email folder. If the email is there, right-click → Not junk so it doesn't happen again.

Outlook may just not have checked yet. In classic Outlook, press F9 or click Send/Receive → Send/Receive All Folders. In new Outlook, click Sync on the ribbon or simply wait a minute — it syncs continuously.

Classic Outlook: look at the bottom of the window. If it says Working Offline or Disconnected, click the Send/Receive tab and click Work Offline to turn it off. It's an easy button to click by accident.

New Outlook: check your internet connection — open a web page. If Settings → General → Offline is on and you've been away from Wi-Fi, mail resumes when you reconnect.

When a mailbox hits its limit, new email bounces back to the sender.

• New Outlook / web: Settings → General → Storage shows how full you are.
• Classic Outlook: File → Info shows a storage bar under Mailbox Settings.

If it's full, empty Deleted Items and Junk, delete old emails with big attachments (search hasattachments:yes and sort by size), or archive.

A rule may be quietly moving or deleting emails. Look at Settings → Mail → Rules (new) or File → Manage Rules & Alerts (classic). Turn off anything you don't recognise, especially rules that delete or forward. Also check Settings → Mail → Sweep for sweep rules.

If you find a forwarding rule you didn't create, change your password immediately — it's a common sign of a compromised account.

Settings → Mail → Junk email → Blocked senders and domains (new) or Home → Junk → Junk E-mail Options → Blocked Senders (classic). If the sender's address or domain is there, remove it.

• Password changed recently? Outlook may be failing to sign in. Classic Outlook shows Need Password at the bottom; click it. New Outlook: Settings → Accounts → Email accounts → Manage → Repair, or remove and re-add the account.
• Account disabled? Try signing in at outlook.com or your provider's website. If that fails, the problem is the account, not Outlook.
• Gmail or Yahoo? Make sure IMAP is still enabled in your provider's settings, and that you've approved any new security prompts.

If everything above checks out and classic Outlook still won't receive:

1. Close Outlook.
2. Open Control Panel → Mail → Show Profiles → Add, create a new profile and add your account.
3. Set Always use this profile to the new one and open Outlook.

Your email comes back down from the server (for Microsoft 365, Exchange, Outlook.com, Gmail and IMAP accounts). POP accounts are different — ask before doing this if you're not sure what you have.

Ask the sender to check their Sent Items and whether they've had a bounce message. A bounce tells you exactly why — a mistyped address, a full mailbox, or their server being blocked. If other people's emails arrive but one person's never do, the problem is usually on their side or in your organisation's spam filter.

Other tab, Junk, F9, Work Offline, storage, rules, blocked senders, account. Nine times out of ten the email is sitting in Other or Junk — and the tenth time, it's a rule or a full mailbox.
