Hi @Bill Gahagan
Welcome to our forum!
Looks like the issue is more related to your account, please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client. It's suggested that you could post your case in dedicated forum for Outlook.com for more professional advice.
As far as I know, when you respond to a meeting request, Outlook usually sends the meeting request to the Deleted Items folder. To change this setting and hold the meeting request:
Go to the settings of your Outlook.com PWA>>Calendar>>Events and invitations>>Invitations from other people.
