Cannot able to remove a member from group:

Hi,

I got a group named compensation currently having 3 members say X, Y, Z. I'm trying to delete 2 of them by find user x, then going to his groups, selecting one of his group Compensation and then

clicking on delete button.

I see a error mesage saying: Email Aliases contain invalid address.

All our users are synced with LDAP.

Please help. I searched all our forums on this error. But I found nothing.

Please see the below screen shot:

Thanks,

krishna
