Hello,
as an admin, I deleted some of the students that don't attend our school. I did it in Directory -> Users + in groups as well. Everywhere in the Console they have been deleted. However, when I start typing a name in the address field ("To:") in my school G-Mail, all the deleted students still appear there as if I could write them an email. This doesnt happen in my admin G-Mail but only in "regular" teacher's gmails.
In a few years, there will be 20 "Johns" out of which 15 won't be there anymore. How can I get rid of it?
Thanks in advance.
Ondrej
