Hi, I am an independent advisor and would like to help you resolve your issue.
i am sorry to say but connected account feature of outlook.com has it own limitation
note->Important information about syncing connected accounts
Syncing from your connected account to your Outlook.com account is one-way only. Email sent from your connected account using Outlook.com will not appear in your connected account Sent Items.
If you delete, move, or read an email from a connected account in Outlook.com, you won't see those changes when you go to your connected account.
For example, email sent from your Gmail account using Outlook.com will not appear in your Gmail Sent Items, and Gmail messages deleted in Outlook.com will not be removed from your Gmail Inbox.
refer->https://support.microsoft.com/en-us/office/add-...
so making any changes to your aol account in outlook.com wont reflect in your aol main account
Hope this information is useful. Feel free to post back if you need more help. I will be glad to help you.
Regards,
Himalay
