The consultants were great! I'm very happy w/ my decision for this vendor - they helped me get setup within weeks vs years from big vendors. Also we had an initial issue after migration where some emails went thru but did NOT update in Outlook calendar -- which was really frustrating because it showed up like all others (they fixed quickly). We ran into issues during upgrade process due to out-of date hardware components / misconfigured devices at endpoints & mail servers (which wasn't resolved by support) I have been working for this firm since it was known simply by its acronym ACI (American Computers). They were one step ahead in terms of computer hardware/software products available at affordable prices back then! Their service is very reliable - no matter what they say or promise you will get exactly your money's worth from them because there isn't much room left between "what we do" & reality when dealing wtih such an established organization like theirs!!
