I saw your product and thought i would give it a test drive. It works great for gmail and office 365 on a windows machine. The challenge is that i use a Mac for my daily tasks.
I am currently running the latest free trial version: 8.1.1083
I have followed the recommended things like changing default behavior for exchange online Oauth and setting default browser. None seem to work.
I would really like to purchase your product but cant justify it if it is not working as intended.
