I spoke with a customer service team member. He confirmed that this is a valid email from Adobe. We send such messages when there is an update to an Adobe ID.
Here’s what we think has happened:
From your description it sounds like your original Adobe ID did not match the new required format (an email address). You may have recently logged into Adobe.com and been asked to change your Adobe ID to email address. After you changed it, Adobe would send this email message to verify the ID change.
I’m going to send you a private email asking for your Adobe ID, so we can check to make sure this has happened.
Thanks,
Kirsti
