I got an email saying OSU will no longer forward email to alumni accounts after December. No big deal because I don't use it but all the current students probably do and if they lose the ability to get mail at their @osu.edu account it will be a mess. My son, for example, uses his @auburn alumni account as the email for streaming service login email; I suspect many OSU students do the same.
I use my grad school alumni email for a number of research sites.
I can't believe OSU's best solution is to simply end forwarding becasue Google can't handle it.
