Hi, Denis,
Check your Outlook to determine if you're running 32-bit or 64-bit Outlook. Not sure what version you're using but click on the File tab and select Help if it is there or, if not, Office Account. If you've selected Office Account, click on the About Outlook icon next.
Adagio is a 32-bit application and will only communicate with 32-bit MAPI clients.
With respect to when you are using the Direct option, you need to ensure that the Port is what is actually being used. Adagio defaults to Port 25 but they may not be the case for all.
The Mail Server must be specified correctly.
As well, your email might require that the TLS/SSL option is enabled or require authentication.
