Often when using Microsoft 365 from another organisation, for example your place of work, or another organisation that you work or volunteer with, you might find that you are asked whether you want to "Use this account everywhere on your device". Often without realising, people click on the blue "Yes" button for this - however in some cases this can impose some problems and/or restrictions on your PC that you didn't want.
If you continue to face issues with disconnecting your Microsoft 365 account from your PC - please raise a support ticket with our helpdesk by emailing support@blackowl.co.uk.
