how to prevent users from login to their personal office365 account?
Use the "block sign-in" option in the O365 portal?
thanks. How does this prevent user from login to their personal account when they are in the company network?
Well it helps when you give more than a one-line description of the issue. If by personal you mean their own O365 subscriptions or in general any "non-company" O365 tenant, you can use the "tenant restrictions" feature: https://docs.microsoft.com/en-us/azure/active-directory/active-directory-tenant-restrictions
Tenant restrictions prevent users from logging into other business tenants, but there doesn’t seem to be a way to prevent users from logging into their personal outlook accounts (e.g. hotmail).
We can block personal OneDrive by blocking specific live.com endpoints, but that doesn’t work for Outlook.
Does anyone know how to block our business users from logging into their personal (eg non business tenant) Outlook and creating a data leakage concern?
