Not able to migrate to a new email adress

[lucas_santucci2]

Hello

I work at the university of bern and have an issue with 3 Users.. 2 of them can't login anymore because there was trouble with the new account that was automatically created by the university of bern. We changed from "@iml.unibe.ch" to @"@unibe.ch" few years ago.. the people who still had "@iml.unibe.ch" are experiecing trouble with logins.. 

The third User i want to prevent to have the same problem but the constelation with the email are the same as by the other two.

Thanks in advance
