User not getting emails and invites

We have a User who has not been getting emails or invites since December. Her settings appear to be correct. Any suggestions on how to reinstate those?

One theory is that she set her email to spam but not sure how this can be rectified on either her end or admins.

Any help appreciated as we’ve had no response from corporate.

It was marked as spam.
Under communicate, drop down to communication problems.
There was a grey button that said TT emails marked as spam.

Hi Alicia,
I’m sorry I didn’t get back to you sooner. I recently had surgery and the recovery has caused me to fall behind on emails.

From the communication problems page you can remove the spam report and then they will resume receiving emails.
