    Hi @Glenn Maxwell , agree with the suggestions above, and it should be the easiest way to meet your needs.

    The test result here:

    Locate to O365 Admin center, Users, Active users, choose the user you want to deny access, block sign-in23020-qa-2020-09-08-10-11-09.png

    23028-qa-2020-09-08-09-52-13.png

    After you block this user, he/she will not be able to login the account through OWA, outlook and any other ways

    However, other people who has full access permission will see new mails sent to his mailbox as well:

    Hi,

    You can try setting the sign-in status to blocked in Office 365 Admin center for the user.

    1. Sign in to the Office 365 portal as an admin.
    2. Users -> Active Users -> Locate the user, and then open the settings for that user.
    3. Under Set sign-in status, click Blocked, and then click Save

    This will not allow the user to login to the Office 365 and access the mailbox but the mailbox will be active and emails will be received.

    Also, you can disable the AD account of the user and sync it with the office 365, so the user cannot login to the mailbox but the mailbox will continue to work.

    To confirm whether the mailbox receives the email, you can send a test email and assign full access permission to your account on that mailbox and login using OWA to check the mailbox.
