Good timing, I'm in the process of looking to migrate my emails. Currently on O365 for 3 of us, but as we now all get Office products via work, I can't justify paying ~£30 a month.
Looking at our usage, the biggest account is 3.7GB, and in the last 180 days the most emails sent was 12 in one day, and the most received was 158 - so micro looks like a fit.
The pricing looks pretty spot on for what we need, and the features seem good, so I've set up a 14day trial with just my email to see how it goes.
I guess the only thing is calendar and contact sync, (I tried to get the calendar to work, but keeps saying it does not exist /shrug)
Any recommendations for a calendar/contact provider?
