    Hi Mary Feeney,

    It sounds like your email account may be experiencing some misconfiguration, possibly related to an automatic reply or forwarding rule that is causing these issues. Here's how to troubleshoot and resolve this problem:

    1. Check Forwarding Rules:

    Go to View all Outlook settings > Mail > Rules.

    Look for any forwarding rules or rules that could be automatically replying to messages.

    If you see any rules that look suspicious or are not set up by you, delete or disable them.

    1. Check Email Forwarding:

    Go to View all Outlook settings > Mail > Forwarding.

    Make sure that email forwarding is either turned off or correctly configured. If there is an invalid email address listed, remove it.

    I hope this information has been helpful. If you have any questions, please let me know and I will be happy to help you further.

    1. Alias or Proxy Address Misconfiguration:

    If your account uses aliases (e.g., ******@domain.com and ******@domain.com), a typo in the alias setup could cause errors.
