There is an email in my inbox that I cannot delete. Each time I try to delete it, it triggers a computer freeze.

This behavior matches a browser-based scam or malicious pop-up more than a normal email delete action. If the screen says the computer is locked, close the browser session instead of interacting with the message.

  1. Press Ctrl+Alt+Del.
  2. Open Task Manager.
  3. End all browser processes.
  4. Reopen the browser and avoid restoring the previous session if prompted.

If the problem is only tied to that one message in Outlook, try deleting it somewhere else first to isolate whether the issue is with the local app:

  1. Sign in to the mailbox in a web browser and try deleting the message there.
  2. If available, try deleting it from the Outlook mobile app.
  3. If it deletes elsewhere, the issue is likely a sync or local Outlook problem on that PC.

If Outlook itself freezes when deleting or sending mail, use these Outlook checks:

  1. Start Outlook in safe mode: open Run, type Outlook.exe /safe, and select OK.
  2. If the issue stops, disable add-ins: File > Options > Add-Ins > COM Add-ins > Go, clear the check boxes, then restart Outlook.
  3. Check whether antivirus integration with Outlook is causing the freeze. Warning: changing antivirus settings can reduce protection, and Microsoft recommends using this workaround at own risk.
  4. If Outlook remains unstable, create a new Outlook profile: Control Panel > Programs > User Accounts > Mail > Show Profiles > Add.

If the message is stuck in Outbox or Drafts rather than Inbox, set Outlook to Send/Receive > Work Offline, then delete the message or remove any large attachment, restart Outlook if needed, and turn Work Offline off afterward.
