Thanks for your support it helps but this is an explanation about the case: In Android we have outlook for personal profile and outlook for work profile. We deployed conditional access policy to block the email on personal profile with granting access to work profile, it worked fine but our target is to force the users that are logged in on personal outlook app before applying the policy to sign out.
Removing Outlook's current configuration (and the data inside) is difficult. That was possible when it still was ActiveSync, but Outlook is different... Conditional Access will stop those clients from syncing data to their device, but was has been already synced will stay
