Email message alerts

Question

In Outlook, how do I set up email message alerts that stay persistently?

Answer 1

Hi there, checking in if you are still hitting the issue.

Answer 2

If you want a permanent pop up, you can create a rule to apply to all emails to you to to display a specific message in the New Item Alert window.

Answer 3

Hi,

I assume you mean desktop notification - the desktop alert is a toast notification that fades after a few seconds by design. Here is something that might work, but it is for all notifications, I am afraid.

1. Press Windows + I to open Settings
2. Go to Accessibility → Visual effects (Windows 11) or Ease of Access → Display (Windows 10)
3. Find "Show notifications for" and change the duration from the default 5 seconds up to 5 minutes

Also,

1. Open Classic Outlook → File → Options
2. Under Mail → Message arrival, check "Display a Desktop Alert"
3. To keep the alert visible temporarily, hover your mouse over it — this pauses the fade-out timer.

I hope this information helps. If you have any more questions, don't hesitate to reach out.

Otherwise, please take a moment to rate the answer. Wishing you good luck!

Answer 4

Classic Outlook does not support truly permanent, never-disappearing pop‑up alerts, but it can show Desktop Alerts for new messages and keep them visible longer by hovering over them.

To turn on and use Desktop Alerts in Classic Outlook for Windows:

1. Open Classic Outlook.
2. Select File > Options.
3. Select Mail.
4. Under Message arrival, check Display a Desktop Alert.
5. Select OK.

Behavior and how to keep them visible longer:

• A Desktop Alert appears briefly when a new email, meeting request, or task request arrives in the Inbox.
• To keep a specific alert on screen so it does not fade away, move the mouse pointer over the alert before it disappears; it will remain visible until moved away or dismissed.

If Desktop Alerts are not appearing:

• They do not appear during initial mailbox synchronization or when using manual Send/Receive.
• If rules move new messages out of the default Inbox, Desktop Alerts might not show for those messages.

For follow‑up reminders (which are persistent dialog boxes until dismissed), messages can be flagged with reminders instead of relying only on Desktop Alerts:

1. Open the message to send.
2. On the Message tab, select Follow Up > Custom.
3. Check Flag for Recipients.
4. Optionally change Flag to text to describe the action.
5. Set a Reminder date and time so a reminder dialog appears for the recipient when due.
