According to this email, you have received a quotation request via the Microsoft document share portal.
The email includes a button that you can click to access the document. It notes that you will need to authorize email account ownership to view or download the document.
However, the email is not from Microsoft and is not a legitimate shared document notification. It is a phishing scam designed to trick you into giving your email account login details to criminals.
If you fall for the ruse and click the link, you will be taken to a compromised website that harbours a scam login page. The bogus page asks for your email address and email account password. If you go ahead, scammers will collect the details you supply and use them to hijack your email account and any linked services.
Once they have gained access, the scammers can send spam, scam, and malware emails in your name. Depending on the type of account that you have, they may also be able to download files you have stored online and conduct fraudulent transactions via a connected app store.
Email account phishing scams like this one continue to be a common Internet security threat. It is always safer to access your online accounts via a legitimate app or by entering the address into your browser rather than by clicking an email link.
