Hi, Can someone help. I saw a unusual login on a device. Deleted the device. It was not malicious and now when I try and login to Outlook it says 'Device was deleted by Administrator' Any advice how to add this device back in simply? I'm not a tech wizz. I have the log that says when I deleted it and the Device ID, Object ID, Device name etc.

Kind regards, Iso

    Try this:

    https://techcommunity.microsoft.com/t5/microsoft-entra-azure-ad/how-to-recover-or-re-add-device/m-p/1250422

    Open the command prompt as an administrator
    Enter dsregcmd /forcerecovery (You need to be an administrator to perform this action).
    Click “Sign in” in the dialog that opens up and continue with the sign in process.
    Sign out and sign in back to the device to complete the recovery.
