Remove the e-mail adress from any Alarm, Report and delete the email Adresse from the user. Than delete the e-mail adress in the recipients list. If this dont work the e-mail adresse ist listet anywhere in any Report, any Alarm or in any User.
So you are saying that I have look in every report or alarm and then remove any target e-mail addresses before I can remove them from ESM's recipients list? This sounds very tedious and would take quite a while; I hope that someone knows of a better way.
i found only this solution. I tried it on ESM 9.5.0
