Is the email I received genuine from Microsoft, and have I been over charged?

I received an email from ******@infomails.microsoft.com saying that : In October 2024, we announced changes to our Microsoft 365 pricing for subscribers in Australia. We recognise we could have been clearer in our communications about the full range of Microsoft 365 subscription options including the option to switch to Microsoft 365 Family Classic. Our relationship with our customers is based on trust and transparency and we apologise for falling short of our standards.

We want to ensure you have all the information you need to make the choice that’s right for you, so we are sharing that information below, including the opportunity to receive a refund.

• Microsoft 365 Family includes the core Microsoft 365 apps plus our AI assistant Copilot and ongoing feature updates. 
• Microsoft 365 Family renews at $179 AUD per year tax inclusive.

Option 2: Switch to Microsoft 365 Family Classic and receive a refund

Is this a genuine email from Microsoft? Is it safe to click the link in the email? I was wondering how the price has jumped so much. I have always paid $139 and now it was $179.
