    Microsoft サーバーがあなたのアカウントを未成年の子供のアカウントと認識した場合、アカウントの生年月日を変更するのは非常に困難になる可能性があります。このリンクで提供されている手順に従って、アカウントの生年月日を変更してみてください。

    Currently, it is not possible to globally enable or disable the birthday calendar at the tenant level in Microsoft Outlook or Outlook on the web. If the option to change the date of birth (DOB) is grayed out, it may be due to restrictions in the settings or permissions associated with your account. You may need to check with your user administrator if you are unable to make these changes yourself.

    For individual users, they can enable or disable the birthday calendar in their Outlook client or via Outlook on the web, but this does not affect the tenant-level settings.
