If you're in an area that has highly trained technicians to support the Mitel MiCollab product - I think your experience will likely be much better than ours. In my opinion, Frontier (and Integra before them) were the worst, and we do not look back on that experience with much happiness.
If you don't have a huge budget and want something that works with minor quirks here and there then Zoho Mail is definitely something you should look into. For half the price of Google G Suite or Office account you get 5GB of storage per user and can send up to 25MB emails without restrictions. Great for small businesses in my opinion. I have had some issues with their spam filter, but we use SpamTitan and just shut off the one that comes with Zoho Mail. Zoho's spam filter isn't horrible but you should definitely use something in addition or instead of what comes with Zoho.
I really like that there is a free version in which a single user can be created. It is really useful because it allows you to evaluate each characteristic of the service without having to buy it.
I also really like the visual aspect of the inbox, which is partially customizable. Because you can make small changes such as changing the color, the language, and among other things.
It is easy to you for existig Mitel UC users, who are familiar with the Mitel way of things, but for green field enterprises, might be a ramp up period which in most cases would not be worth it as its competitor TEAMS is much easier and intuity to use.
It is very easy to use and does all you need. It sends newsletters to their own folder. A notification folder for more important things. The Spam folder collect the right amount of spam emails
Initially, support from Mitel was fantastic, but recently it has started to lag significantly. Response takes 8 hours, at a minimum, usually requiring a second call to spur a response. Email support is even worse (email in a ticket) - I have had to call in to get things running the 3 times I've tried to email support.
I have spoken with Zoho several times and their support is always friendly and helpful. I have always been asked for security pins and codes when seeking assistance which helps me to feel my accounts are secure and I have never had to wait on hold to speak with someone for more than 5 minutes. They always seem to have someone available to help. If you call asking for instructions on how to do something they gladly walk you through the process and if you just need something done and don't have time to do it yourself they will happily customize whatever you need without you having to spend all day with it.
MiCollab was great as a VOIP solution and general team collaboration solution, but it lacked in some areas, such as the mobile app, complex configuration and set up as well as the lack of user customization. Overall, the system is serviceable, but seemed rather vanilla compared to its competitors
Zoho is free. Also, there is no need for a separate IT guy for creating mail, or if any issues come you don't have to find anyone anyone can check and fix all issues from their super admin panel. Zoho overview is much better than outlook and its appearance of getting mail popup and functionality is better than outlook. My friend suggested for this and also after using I have referred my friend
This product was competitively priced when originally purchased. We will need to evaluate whether to replace it when it approaches the end of life or simply upgrade it.
Users typically only use the phone system because the collaboration tools have been superseded in functionality by other tools.
