What do you like best?
I have used MiCollab for chatting and making phone calls, but it really lacks in user customization as far as font choice, window color, etc, go. Paired with Mitel phones, checking missed calls and voicemails is pretty easy, and the directory list makes it easy to call anyone in the company without having to look up their extension.
What do you dislike?
Older versions generally didn't want to play nice with Windows updates, so in order to have MiCollab work, we needed to stop a lot of Windows updates from rolling out. That seems to have been fixed in 7.2, and we haven't had an issue with Microsoft's CUs for Windows 7 or 10 interfering with MiCollab operation yet.
Recommendations to others considering the product
The real-time access to everyone in the organization regardless of location will help make everyone's days more efficient! Mitel MiCollab Client is the perfect addition to all MiVoice phones. If you're looking for an advanced Unified Communications solution Mitel's MiCollab Client will get you there. The client works great on your PC, MAC, or smart device!
What business problems are you solving with the product? What benefits have you realized?
One of my favorite features is Exchange calendar integration that shows everyone else on MiCollab when my next appointment is so they know when not to call. I would like to see more customization options, though, so that MiCollab would work better with inverted or high-contrast color schemes.
