Outside company email removal

Dear Steve,

The steps depend on where the outside email address is saved.

If it's saved as one of your own contacts, you can delete it in Outlook on the web:

1. Select People in the left navigation.
2. Search for the contact's name or email address.
3. Select the contact, then choose Delete.

If the address is part of a contact list, deleting the contact won't remove it from the list. To remove it from the list:

1. Go to People > Your contact lists.
2. Select the list and choose Edit.
3. Select the X next to the address, then choose Save.

If you don't see a Delete option, the contact is likely part of your organization's address book. Only your Microsoft 365 administrator can remove it from the Exchange admin center. If you don't know who your IT administrator is, please refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support 

I hope this helps. Looking forward to your reply.
