It sounds like the emails you received could potentially be phishing attempts, especially since they are unsolicited and the sender URLs look suspicious. Microsoft typically sends emails from specific domains such as microsoft.com, microsoftsupport.com, or mail.support.microsoft.com. If the emails are coming from different domains, they are likely not legitimate.
You should not click on any links or provide any personal information in response to these emails. Instead, you can verify any updates regarding terms and conditions by visiting the official Microsoft website directly. If you suspect that the emails are phishing attempts, you can report them to Microsoft.
