I am collecting identities from a csv files and also I have an IDC for collecting email address from AD. When a user is terminated his/her AD account is disabled then deleted in 30 days. This causes the loss of recent email address for those identities which are terminated more than 30 days.
Unfortunately we have some applications where accounts are not deleted only disabled and are identitfied by email address. In this case I am losing the mapping as the email address does not exist in IGL anymore.
Best solution would be keeping the email of the terminated users even if it is not collected anymore. Any idea how to do it? Maybe some other best practice to deal with such disabled accounts?
