Many users switching from Classic Outlook to the New Outlook struggle to find familiar mail tip settings. Mail tips are alerts that appear when you send email, such as warning you about a large attachment, a reply-all risk, or an out-of-office recipient. In Classic Outlook, these settings are tucked away in the Options dialog. In New Outlook, the same features are located in a different menu structure. This article explains where each mail tip setting lives in both versions so you can configure them without frustration.
Key Takeaways: Finding Mail Tip Settings in New and Classic Outlook
- File > Options > Mail > MailTips in Classic Outlook: Access all mail tip toggles and the MailTips bar configuration.
- Settings > Mail > Compose and Reply in New Outlook: Adjust mail tip behavior and enable or disable specific alerts.
- MailTips bar settings in Classic Outlook: Control what triggers a MailTip via the MailTips button in the Options dialog.
What Are Mail Tips and Why Do They Matter?
Mail Tips are real-time alerts that appear in the message composition window before you send an email. They help you avoid common mistakes such as accidentally replying to all recipients, sending a large attachment that exceeds the server limit, or emailing someone who has set an out-of-office autoreply. In both Classic Outlook and New Outlook, these tips appear as a colored bar at the top of the compose window, but the settings to customize them are in different locations.
Understanding where to find these settings is important for business users who need to enforce company policies or personal preferences. For example, an administrator might want to disable the large attachment warning if the organization uses a file-sharing service, or a user might want to enable the reply-all warning for all messages. The configuration differs significantly between the two Outlook versions.
Mail Tip Categories
Mail Tips fall into several categories, each controlled by a separate toggle or setting:
- Large attachment warning: Alerts you when an attachment exceeds the size limit defined by your Exchange server (typically 10 MB to 25 MB).
- Reply-all warning: Warns you when you are about to reply to all recipients on a message that has a large number of addresses.
- Out-of-office notification: Shows a tip when one or more recipients have an automatic reply set.
- Restricted recipient warning: Alerts you when you are sending to a recipient who has restrictions, such as a distribution group that is moderated.
- External recipient warning: Notifies you when you are sending email to someone outside your organization.
Where to Find Mail Tip Settings in Classic Outlook
Classic Outlook stores mail tip settings in the Options dialog under the Mail section. The exact path is:
- Open File > Options
In Classic Outlook, click the File tab in the ribbon, then click Options at the bottom of the left pane. - Go to Mail > MailTips
In the Outlook Options dialog, select Mail on the left sidebar. Under the Compose Messages section, click the MailTips button. This opens the MailTips Settings dialog. - Configure individual MailTips
In the MailTips Settings dialog, you can check or uncheck each MailTip type you want to enable or disable. Options include: Large audience, External recipients, Restricted recipients, and Large attachment. You can also set the threshold for the large audience warning (default is 25 recipients). - Adjust the MailTips bar behavior
Still in the MailTips Settings dialog, you can choose whether the MailTips bar appears automatically or only on demand. Select the option that fits your workflow.
After making changes, click OK twice to save. The settings apply immediately to all new messages you compose.
Where to Find Mail Tip Settings in New Outlook
New Outlook uses a simplified settings interface. Mail tip controls are located in the Settings panel under Mail > Compose and Reply:
- Open Settings
Click the gear icon in the top-right corner of the New Outlook window. Alternatively, press Ctrl+Comma. - Go to Mail > Compose and Reply
In the Settings panel, click Mail on the left, then select Compose and Reply from the sub-menu. - Scroll to the MailTips section
Scroll down the Compose and Reply page until you see the MailTips heading. Here you will find toggles for each MailTip type: Large attachment warning, Reply-all warning, Out-of-office notification, Restricted recipient warning, and External recipient warning. - Toggle each MailTip on or off
Use the switches to enable or disable each tip. Changes save automatically.
Note that New Outlook does not offer a MailTips bar behavior setting. The bar always appears automatically when a tip is triggered. You cannot change this behavior in the current version.
If Mail Tip Settings Are Missing or Grayed Out
MailTip settings are grayed out in Classic Outlook
This happens when your mailbox is not connected to an Exchange server, or when your organization enforces MailTips via Group Policy. If you see grayed-out checkboxes, contact your IT administrator. MailTips require an Exchange Online or on-premises Exchange account to function.
MailTip toggles are missing in New Outlook
New Outlook may not show MailTip settings if you are using a personal email account (such as Gmail or Yahoo) instead of a Microsoft 365 or Exchange account. MailTips only work with Exchange-based accounts. Switch to a supported account type to access these settings.
MailTips appear but do not display in the compose window
In Classic Outlook, if you have disabled the MailTips bar in the MailTips Settings dialog, no tips will show. Go back to File > Options > Mail > MailTips and ensure the option to show the MailTips bar is checked. In New Outlook, there is no such toggle, so if tips are missing, verify that your account is Exchange-based and that the individual tip toggles are enabled.
| Item | Classic Outlook | New Outlook |
|---|---|---|
| Location of settings | File > Options > Mail > MailTips button | Settings > Mail > Compose and Reply > MailTips section |
| Configuration method | Checkboxes in a separate dialog | Toggle switches in the settings panel |
| MailTips bar behavior | Configurable (auto or on-demand) | Always auto, not configurable |
| Threshold for large audience | Adjustable (default 25 recipients) | Not adjustable |
| Account requirement | Exchange or Microsoft 365 | Exchange or Microsoft 365 |
In Classic Outlook, you can also access MailTips settings by right-clicking the MailTips bar in a compose window and selecting MailTips Settings. This shortcut is not available in New Outlook.
For advanced users, you can export and import MailTips configurations in Classic Outlook using the Export/Import buttons in the MailTips Settings dialog. New Outlook does not offer this feature.
If you frequently switch between the two versions, consider saving a screenshot of your Classic Outlook MailTips settings as a reference. This helps you replicate the same configuration in New Outlook without guessing which toggles to enable.
