Let me ask one query which comes directly from Customer's end about the Admin Settings as I am aware that if we block Exchange Active Sync then people from Outlook App will not be able to access the mails whether be in the Organisation or leaving the Organisation. But suppose if an employee left the Organisation and still he/she is able to access the mails from his/her native apps then it's a wrong idea.
How we can restrict them(Don't involve Conditional access as customer is on Plain O365 not looking for MDM) or how we can give offline email access to end users only for limited days! How can we set the same any document for reference will be grateful!!

If an employee leaves, you block sign in to the account. They won't be able to get new mail within 60 min. If you want to remove access to already cached mail, you need to wipe the account from their device.
