Email about deactivating BT email service - is it a scam

[aecadmin]

I've received an email from BT Enterprise Communications saying:

Starting from June 30th, 2023, customers that are yet to update their account will no longer be able to log in via their email addresses due to recent security upgrades.
Please follow the link below to secure your account: 

The email provides our correct email address and it comes from Carlton.blaxhill@btconnect.com 

Is this genuine.  Should I click on the link?

We've had lots of these - definitely a scam.
They come from random btconnect addresses.

Thank you. It keeps coming in and looks genuine. I'll block them.

We've encountered numerous instances of this, and it's undoubtedly a scam. These emails are originating from random btconnect addresses, raising serious doubts about their authenticity and legitimacy. Exercise caution and be wary of such communications.
