Hi @Motsoaledi Neo Tshoana
I’m sorry you’re experiencing this issue. I understand that you have already left the unwanted Outlook.com groups, but they continue to reappear and add your account back without your consent.
Outlook.com allows users to leave a group or stop following group messages. However, I could not find a user-accessible account-level setting that prevents group owners or members from adding the address again. Since this affects more than 20 groups and continues after you leave them, the account will need to be investigated by Microsoft Support.
- Go to Contact Microsoft Support.
- Select Show expanded list of products.
- Select Outlook > Get Home support.
- Enter Outlook live chat, then select Get Help > Contact Support.
- Sign in with the affected account. If that is not possible, use another Microsoft account to view the available support options.
- Ask our Support Assistant > Type "Talk to live chat agent" > Contact Support
- Under Products & Services, select Other Products > Outlook, then choose Chat with a support agent in your web browser.
Please contact Microsoft Support and provide the screenshot, affected group names, and any welcome emails showing who added your account.
Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas only.
Thank you for your understanding.
