i have many times suggested a feature related Group Membership removal should be easy to attract user on corporate level. it is very pathetic method to disable user and find the disable users in different group by clicking and searching.
or you should introduce searching method of email clients in group to remove users easily.
I am currently testing the latest version of MailEnable Enterprise Premium 10.xx but i unable to find the basic feature of users email group membership. At least try to improve Email Group Management or on user panel there must be a tab of groups where he/ she is member of..
kindly consider and respond the query. snapshot attached for your review.
For Example Member of Tab added and shown you here.
