Microsoft 365 does not automatically sync shared calendars one-way to business smartphones.

Fixing the missing sync is not simple or easy

Manual workarounds for syncing shared calendars to smartphones are error prone and time consuming. 

Loss of productivity and revenue for business users

Shared calendars can be accessed in Outlook but employees need access on smartphones. Without immediate access to current shared calendars on smartphones, employees can miss critical meetings, schedule changes, and emergencies.

An Automated Calendar Sync Solution is Vital for Employee Productivity.

Corporate syncing of Exchange Server contents to our users iPhone and iPad devices for calendar and contacts. It has saved a lot of hassle to manage what should be an easy solution for Microsoft, but they don’t handle it at all.
