That is why it is suggested to switch to MS Outlook if you use the Outlook app. For that, open the Outlook app and toggle the button visible in the top-right corner:
Next, click the Continue button to make the switch.

To update MS Outlook, follow these steps:

It takes a few minutes to find, download, and install the update.
To update the new Outlook app, open the Microsoft Store and choose to update the Outlook for Windows app.

3] Use Outlook instead of Gmail or other IMAP accounts

If you use Gmail or any other IMAP/POP account in Outlook, you might not be able to create a contact group. If you use a School or Work account, you will face the same problem as well. The only solution is to switch to @outlook.com or another Microsoft email service.

4] Ensure you have synchronized contacts

Sometimes, you might not be able to find the contact you created in the Web version or Outlook. This is because the contact is not yet synchronized. As a result, you won’t be able to add that contact to the list.
Therefore, before creating a contact list, ensure that all your contacts are synchronized. If not, wait for a few moments.
