The best thing about hostEAM is that it's easy to use, has good support from Microsoft team as well so no issues with compatibility or anything like this! I have used other email providers but they were not very user-friendly compared t he ones we've tried in our organization which are hosted by MS Teams (Exchange Online).
We're solving problems related communication between employees of different departments within an office building using Office 365 services such us Email & Calendar etc.. It helps manage all emails sent out through one account instead having multiple accounts where each employee would be managing their own inboxes separately - This makes things easier when you need help at any time without worrying if someone else will see your message first before replying back because everything gets managed under 1 roof now!! Nothing really comes up against me dislike wise since i haven't found much faults yet :D But there should always come something new every day right? If anyone wants more information please feel.
