For some time now, Outlook has been attempting to create a login via Office 365 by default. In some cases, this can lead to login problems, as Outlook initially assumes that it is a mailbox hosted in the Microsoft cloud.
The following instructions show you how to connect to a local Exchange mailbox instead and thus avoid difficulties when setting up an Outlook profile.
Edit registry entry:
After logging on to your Windows device, you can deactivate the Office 365 preference via a corresponding registry entry.
First download the file disable-autodiscover365.zip, which is available for download at the bottom of this page.
Then unpack the ZIP archive. Inside you will find the file disable-autodiscover365.reg, which you execute by double-clicking.
A security prompt will then appear, which you should confirm with "Yes".
After successful completion of the process, a corresponding confirmation will be displayed.
Please restart Outlook afterwards.
Download the ZIP file:
At this point you can download the ZIP file mentioned above.
