In early September 2024, the Groups feature in Outlook Mobile was deprecated for Outlook.com users. You will be unable to access your Outlook.com Groups from within Outlook for iOS or Outlook for Android. This change only affects Outlook.com users; Office 365 users will still be able to access their Groups from within the client.
We plan to restore access to Groups for Outlook.com users within Outlook for iOS and Outlook for Android at a later date.
