Korzystanie z programu Outlook dla systemu Android na potrzeby zarządzania osobistymi pocztami e-mail i kalendarzami
Thank you for your reply. My account doesn't have any associated devices. As I mentioned, there's no problem creating an account with the same domain from the same service provider. Additionally, there's no problem adding other accounts on multiple devices. In summary: I can add accounts like (for example) ******@pandik.pl and ******@pandik.pl on multiple mobile devices, but I can't add ******@pandik.pl.
Best!
Pawel.
