OPT-OUT new Outlook

Dear blue office® users

Microsoft has decided to change the new Outlook model from opt-in to opt-out. 

blue office® is not yet fully compatible with the new Outlook. 

Since Microsoft will no longer offer the COM interface for the new Outlook, our development team is currently working on revising the necessary interfaces. 

Microsoft will continue to support Outlook Classic until 2029.

Our recommendation for dealers and customers is to currently stick with Outlook Classic.

The transition can be made for Microsoft 365 Apps accounts in the Microsoft 365 Apps admin center.Microsoft 365 Apps admin center) done in Group Policy (or Policy Management). 

Please find the appropriate policy here «Admin-Controlled Migration to New Outlook» / «Admin-kontrollierte Migration zu neuem Outlook» and Turn these off.

We recommend setting up the opt-out promptly.
