The best thing about this product is that it helps you in migrating your mailboxes from one exchange server or mailbox environment into another without any issues at all! It also has some great features like scheduling, auto-reply etc which makes work easy even when there are many users working together over multiple locations as well across different time zones!! As I said earlier above - just try out once because its very helpful during migrations. Nothing really dislike here apart form few minor things but those can be easily sorted by contacting their support team if needed :) Very smooth experience while using these tools so far compared other similar softwares available online now days! We have migrated our email accounts (mailbox) data between two office environments where we had hosted both servers ourselves before switching them entirely onto cloud services offered via Microsoft O365 platform.
