Outlook 2016 connect Office 365 mailbox without Autodiscover
Hi,
following scenario:
We have an on premise Exchange 2010 server with Autodiscover configured internally.
Users have mail-adresses @example.de.
Now I have an Office 365 tenant, where I configured the domain example.de (without MX-entry) and aso set the CNAME autodiscover.example.de to Office 365.
My interal Mail-Clients (all Outlook 2016) won`t connect to the online mailbox because the internal AutoDiscoverURI points to the on premise Exchange server.
As soon as I delete the InternalAutoDiscoverURI the Outlook clients connect to Office 365.
Now I wanted to create some pilot users with mailboxes at Office 365, but I can`t find a possibility to connect Outlook.
For Outlook 203 I found some HowTo like following, that tell me to get the online Mailbox UID.

Is there any possibility to connect Outlook 2016 witho Office 365 without Autodiscover?
We don´t have a connection between on premise Exchange an Office 365, because we are not planning to make a hybrid migration.
We wat to do a custom cutover migration, with a third party tool (Office 365 Office 365 Migration) for migratng data.
But qhat I`m now looking for ist a possibility to start testing before the migration will be done, but I`m not able to do this without a working Outlook connection.
And disabling the InternalAutoDiscoverURL ist not an option, because this would break existing behaviour.
Any suggestions?
Many thanks in advance!
