Great add-on, I paid for the license without blinking.
I recommend this add-on to any TB user who needs to access the Exchange functionalities without hassle.
Very quick, direct response from the dev when serious issue arose once.
Sorry for the problems. Our database server had a hiccup and didn't respond, causing these failures. Really sorry about that. It's fixed now.
