Hi @Waheed Shaik 

you  might need to check that email from User Management view, probably it is disabled/suspended or doesnt have access to the site anymore.

also, worth to check this https://confluence.atlassian.com/confkb/mention-feature-doesn-t-work-for-specific-user-if-disable-autocomplete-option-is-enabled-744527570.html which might be relevant to your query.
