The best thing I like about this product it's easy use, simple interface & It has many features for searching any type information from emails in group or team discussions! Nothing at particular point what i dislike as well but if we talk abt its price tag then also there are some points need attention like:- 1) If one want more than 5GB storage space they have pay additional cost2.) There should be option available while creating new mailboxes where admin/admin person could manage mailbox creation by themselfs instead sending email to support@groupexplorerincorporated (support). We just started using Group explorer last month so no issues till now with us :) Easy way to share files within our Team without much effort required!
