Email locking my account

If you changed your password, then your account hasn't been locked.

That was likely a phishing email trying to get you to reveal your account details to jerks hoping to steal your account.

Delete the email. Never click any links in such an email in the future.

ASC - Late 2012 Mac mini, macOS 10.14.5; Watch, series 3 cellular, watchOS 5.2.1; iPad Air 2 & iPhone 8+, iOS 12.3.2; TV 4th Gen, tvOS 12.3;  HomePods, audioOS 12.3 and Airport Express w/ Airplay 2

Apple won't send you an email/text telling you your account is disabled/restricted  or will be disabled/restricted. You will find out the next time you try to log in somewhere.

Apple will always address you by your name or the name they have on file for you, not Dear Customer, Dear Client or by using your e-mail address.  The e-mail will be from @apple.com or @iTunes.com. E-mail addresses can be spoofed. You can go to Mail/View/Message/Show all Headers to see more. Apple e-mails will never contain an attachment. Apple will never request personal information by email such as Social Security numbers, your Mother’s maiden name or full credit card numbers .

The only exception to the above I have noticed is if you order something from the Apple Store (apple.com), your receipt will be addressed to Dear Apple Customer. That is a receipt for a purchase you initiated.

Avoid phishing emails, fake ‘virus‘ alerts, phony support calls, and other scams

Identifying legitimate emails from the iTunes Store

Send the e-mail to Apple as an attachment to a new e-mail before deleting it. You can forward as an attachment by going to Mail/Message/Forward as attachment. You won’t receive a response.
