Part 1: Why Does Outlook Not Prompting Happen?

There is a wide range of reasons behind this issue. I will let you know some of the significant reasons why Outlook MFA is not working. Let's check them below:

#1: If you are using an outdated version of Outlook, then you might face this issue.

#2: If there are problems with your cached data, then you may face an issue of Outlook MFA not working.

#3: Another reason might be corrupted Windows files.

Part 2: How To Fix Outlook Not Prompting Step-by-step?

As you know the three reasons for this issue, it's time to discuss how to fix Outlook without prompting for MFA step-by-step.

So, let's start with the first method.

Method 1: Update Your Outlook Version

The first method to solve the issue of Outlook not prompting for MFA is to update your Outlook program. As I mentioned earlier that if you are working on an outdated version of Outlook, then your Outlook MFA may not work. This is because older versions' security policies are not advanced as newer ones. So, in this case, all you need to do is update its latest version.

Here are the steps to upgrade the Outlook version:

Step1 Open Outlook. Choose the 'File' tab. You can find this button in the upper-left corner of your Outlook app.

choose file tab

Step2 Choose Account on the File menu. Your account will be opened on a new page.

choose account

Step3 Then, choose the Update Options button. After choosing it, a drop-down menu will display many update options.

choose update options

Step4 Choose "Update Now." Click Enable Updates first if you don't see this option here. Now, the menu must include the Update Now button.

choose update now

If this method does not solve your Outlook issue, then try out the next method.

Method 2: Get Your Cache Cleared

Outlook stores information about emails in your cache so that it won't have to download them again each time it needs a copy.

If there are problems with cached data, clearing it will remove any corrupted entries from your cache and return its settings to normal. This can help you to fix Outlook MFA not working.

So, to fix it, follow the steps mentioned below:

Step1 Press the Windows+R keys. The Run dialog box displays.

run dialog box

Step2 In the Open box, type or paste %localappdata%\Microsoft\Outlook and press the OK button.

type of program

Step3 Locate the RoamCache folder.

choose roamcache folder

Then, double-click on it to check the cache files.

Step4 To choose all the Cache files, press Ctrl+A. Next, right-click and tap on the Delete button in the menu.

choose delete

Step5 All cache files have now been deleted. The RoamCache folder is now empty.

Method 3: Set Your Password Again

It's possible that a recently reset password resulted in an expired MFA token. If so, you will have to add MFA to your account once more. The steps to create your app password again are as follows:

Step1 There is a page that lets you "Reset your password." Get there.

reset your password

Step2 Then, choose why you want to reset your outlook password. Next, tap on the next option.

choose next

Step3 When creating your Outlook account, you will be prompted to enter the recovery email address. Access it.

choose recovery email

Step4 After entering the characters that are shown on the screen, select "Next" from the menu. This step is to make sure you're a real person, not a robot.

Step5 If security info is applied to your Outlook account, a one-time code will be sent to the email address or phone number you provide. The following screen will require you to enter this code. Once you have entered this code into the proper box, you will be able to create a new password.

Now, check if the problem persists after implementing this method. If you still find the same issue, then apply the next method.

Method 4: Close Credential Manager and Start Outlook Again

Another method to access outlook after enabling MFA is to close the credential manager. The steps are listed below:

Remember to exit Outlook before applying the steps. If you do not close Outlook, then the changes will not be saved on Outlook.

Step1 Find "Credential Manager" in the Windows start menu and select the "Credential Manager" control panel.

open credential manager

Step2 Choose Windows Credentials next to see the applications and websites you have been signing into.

open windows credentials

Step3 Next, go to 'Generic Credentials'.

Step4 Then select any entries with "Outlook" or "MicrosoftOffice16" in the name.

Step5 After this, choose Remove.

Step6 Then you can restart Outlook and close Credential Manager. You can now access your Outlook once more as a result.
