Hello, I've got Outlook setup on my personal computer. I am logged in with a personal and a business Account, with an Office 365 License applied to both accounts. Also, some IMAP Accounts, but they shouldn't matter.
I recently got access to another business account which doesn't have a valid license for any desktop apps. Adding the account via autoconfiguration failed, obviously (sadly). Even tho I have the right to use Outlook, so I naturally I want to be able to add all my mail accounts.
The second option I tried was adding the mail via the IMAP servers, provided by the settings in outlook.office.com.
