We have been using SourceOne for a year now, with our EmailXtender server in read-only mode (you cannot move the containers to SourceOne unless you use an expensive tool and months of consultancy). To keep it short ‘we have been conned’, more features in SourceOne – YES, more scalable – YES, better product – NO. We get weekly index corruption, it is even worse the EmailXtender, no public folder archiving and no export to PST option from search results. We are in the process of moving away as to date the index problem has never been fixed and we doubt it ever will be.
