Migrating Zimbra calendars and contacts to Office 365 via the Microsoft Graph API

Folks,

Microsoft is sun-setting Exchange Web Services (EWS) which we have been using for about 10 years for migrations in favor of Microsoft Graph.  So we're porting our code to the next generation of technology.

We've got Zimbra calendar and contacts going into Office 365 via the Microsoft Graph API in our lab and are looking for a few test sites wanting to move calendars and contacts as next generation early-adopters.  

If you can run imapsync or the Microsoft email migration you can use the same permissions to move calendars for all users server-side with no intervention.

And we've radically simplified our interfaces.

If interested drop us a line via our contact page.
