There are a number of factors that Microsoft does not advertise in its marketing message to customers that are well documented on a Number of IT boards and websites:
Migration
Microsoft customers have to pay a third party to migrate their email, contacts, calendar, notes, and tasks. This migration can average 3-5 hrs per mailbox at an average of $150/hr. MDaemon Technologies provides migration services at an affordable rate and if you are currently using MDaemon, migration is a quick and seamless process.
Cost and Flexibility
Microsoft 365 plans aren’t as cheap as you think. Most customers fall into either the $12.50 or $20.00/month/user package (these are the plans that entitle a user to desktop versions of Office). If you have a need for archiving or data protection (ie Legal Hold or Data Loss Prevention), you pay $20.00/user/month. Microsoft 365 requires every user to be on the same plan. So, executive "power users" that have more expensive Microsoft 365 feature needs will force the entire organization to pay the higher rate. MDaemon Hosted Email is $5.00/user/month plus $2.00/user/month for each user you add Outlook/ActiveSync support to.
Privacy
Microsoft cannot guarantee where your data will reside. MDaemon Technologies will tell you where your data is and it stays private with you.
Support
One of the biggest complaints from Microsoft 365 customers on IT community websites or performance sites like www.downdetector.com is the slow or unhelpful support from Microsoft. MDaemon Technologies built its business on listening to its customers. You can rest assured that you will not be thrown into queue of one of the largest companies in the US hoping to get your issue resolved in a timely fashion.
