If you have not yet completed the activation, you can do so on the following page: o365portal.semmelweis.hu and click on the 'Activate ID' button.
If you have previously activated your O365 account, you can request a new password on the following page: https://o365portal.semmelweis.hu/Home/ForgottenPwd
Check your browser's password manager, as it may have saved a password that is not your O365/Outlook password, but is used for Aptitude login instead!
