What Outlook Classic is and why you might add it to Intune
Outlook Classic is the older version of Microsoft Outlook that runs on Windows computers — the one that looks different from the newer Outlook app you may have seen. If your workplace uses Intune (Microsoft's device management system), you might need to add Outlook Classic to it so that your IT department can manage security settings, require passwords, or control what data the app can access.
Most people encounter this when their company switches to Intune and wants all email apps on company devices to follow the same security rules. Outlook Classic is not automatically included in Intune's protection, so you have to add it manually through a few straightforward steps.
The process takes about five to ten minutes and requires you to have Intune Company Portal already installed on your computer. If you do not have it yet, your IT department should have sent you a link or instructions to install it first.
Key Takeaways
- Outlook Classic must be added to Intune separately — it does not automatically appear in your device's protected apps.
- You need Intune Company Portal installed on your Windows computer before you can add Outlook Classic to it.
- The process involves opening Company Portal, finding the app protection settings, and selecting Outlook Classic from a list.
- After you add it, your IT department can enforce security rules like password requirements or data encryption on Outlook Classic.
Install Intune Company Portal if you have not already
Before you can add Outlook Classic to Intune, you need the Intune Company Portal app running on your computer. This is the app that connects your device to your company's Intune system. If your IT department sent you a setup email or link, that is usually the fastest way to get it.
If you do not have a link, open the Microsoft Store on your Windows computer, search for "Intune Company Portal", and install it from there. Once it is installed, open the app and sign in with your work email address and password. Your IT department may have given you a different password for this — check your setup email if the one you normally use does not work.
After you sign in, the Company Portal will show you a list of apps and settings your company manages. This is where you will add Outlook Classic in the next step.
Open the app protection settings in Company Portal
Once you are signed into Company Portal, look for a section called App Protection or Protected Apps — the exact name varies depending on your company's Intune setup. This is usually in the left sidebar or in a menu at the top of the window.
If you do not see it when ready, look for a settings icon (usually three horizontal lines or a gear symbol) and tap or click it. From there, you should see options related to app management or protection. Your IT department may have also sent you a direct link to this section — if so, clicking that link will take you straight there.
Once you find the app protection section, you will see a list of apps that are already protected, or a button that says something like "Add App" or "Manage Protected Apps". Click that button to move forward.
Search for and select Outlook Classic
After you click the button to add an app, a window will open showing available applications. You will see a search box at the top. Type "Outlook" into it — do not type "Outlook Classic" or "Outlook Desktop", just "Outlook".
The search results will show you different Outlook versions. Look for the one labeled Microsoft Outlook (without the word "new" in the name). The newer Outlook app is usually labeled "Outlook (new)" or "New Outlook", so make sure you are selecting the classic version. If you are unsure which one is which, ask your IT department — they can tell you which version your company uses.
Click on the correct Outlook version to select it. Some Intune setups will ask you to confirm this choice or choose protection settings at this point. If a dialog box appears asking about password requirements, data encryption, or other security rules, your IT department should have told you what to select — if not, the default settings are usually fine, and you can change them later.
Confirm the addition and wait for the policy to explore
After you select Outlook Classic, Company Portal will show you a confirmation screen. Click the button to confirm or save your choice — this is usually labeled "Save", "Confirm", or "Add". The app will then process your request.
It can take anywhere from a few minutes to a few hours for the protection policy to actually explore to Outlook Classic on your computer. You do not need to do anything during this time — just leave your computer on and connected to the internet if possible. Your IT department can see when the policy has been applied on their end.
Once the policy is active, Outlook Classic will start following your company's security rules. You may notice new prompts asking for a password when you open the app, or you might see a notification that data is now encrypted. This is normal and means the protection is working.
Troubleshooting if Outlook Classic does not appear in the list
If you search for Outlook and do not see the classic version in the results, it usually means one of two things: either Outlook Classic is not installed on your computer, or your company's Intune setup does not support it yet.
First, check whether Outlook Classic is actually installed. Open your Windows Start menu and type "Outlook" — if you see "Microsoft Outlook" (the older-looking icon, not the colorful new one), it is installed. If you do not see it, you need to install it first. You can do this through Microsoft Office if you have it, or ask your IT department for installation instructions.
If Outlook Classic is installed but still does not appear in the Company Portal list, contact your IT department. They may need to add it to your company's Intune configuration, or there may be a different process your company uses for this particular app. Do not try to work around this — your IT department needs to know so they can set it up correctly.
What happens after Outlook Classic is protected
Once Outlook Classic is added to Intune, your company's IT policies will explore to it. This might mean you need to enter a PIN or password each time you open the app, or that your emails are automatically encrypted. Your IT department controls these settings, not you.
If you have questions about what the new rules are or why they are in place, ask your IT department — they can explain the specific policies your company has set. If the new requirements cause problems with your work, let them know so they can adjust the settings if needed.
You do not need to do anything else after this point. Outlook Classic will continue to work normally, just with the added security your company requires.
Frequently Asked Questions
Do I need to uninstall the new Outlook app if I am adding Outlook Classic to Intune?
No. You can have both versions installed at the same time. However, if your company only wants you using Outlook Classic, your IT department will let you know and may remove the new Outlook app from your device themselves through Intune.
Will adding Outlook Classic to Intune delete my emails or settings?
No. Adding it to Intune only applies security policies — it does not change your emails, contacts, or how the app works. Your inbox and all your messages will stay exactly as they are.
What if I see an error message when trying to add Outlook Classic?
Error messages usually mean either Outlook Classic is not installed, or there is a temporary connection problem with Company Portal. Try restarting both Company Portal and Outlook Classic, then try again. If the error continues, contact your IT department with the exact error message you see.
Can I remove Outlook Classic from Intune protection later?
Technically yes, but your IT department may have policies that prevent this or require them to approve it. If you need to remove it, ask your IT department first rather than trying to do it yourself.
How long does it take for the Intune policy to show up in Outlook Classic?
Usually between a few minutes and a few hours. If it has been more than 24 hours and you do not see any change, contact your IT department — there may be a delay on their end or a configuration issue.
