Hi there Marie-LouiseMLD,
Welcome to Microsoft Community
I'm Bobadoye and I'd be happy to help you out with your question.
It’s always a good idea to be cautious when receiving emails from unknown senders, especially if they ask you to click on a link or provide personal information.
You can open the email and check if it has any link or attachment, but do not click on any, Check the content of the email: Look for any spelling or grammatical errors, as these can be a sign that the email is not legitimate. Also, be wary of any urgent or threatening language, as scammers often use these tactics to pressure people into taking action.
You can check your OneDrive for any updates or any changes.
I hope this information helps. If you have any questions, please let me know and I'll be glad to assist you further.
Best Regards,
Bobadoye
