I like how it has multiple options to search through as well if there are more than 1 email accounts being used with this program; however i dislike having 2 different programs open when using Outlook 365/365 Pro but its what we use so thats ok! Honestly haven't noticed too much problems or anything yet other then just getting familiar woth everything which takes some doing since they do have alot going into their software!! But overall not many issues right now either way would recommend them because most companies these days will require something from Microsoft anyways (Outlook) So why go anywhere else? Just get an Exchange account set up first before purchasing any mail management services otherwise things may run slow once implemented due t he amount needed per mailbox etc..
