Hi,

Hope someone can help me on this.

1. When can I upgrade to Microsoft Dynamics CRM 2016 online ?

2. Can I use Microsoft Dynamics CRM 2016 for Outlook on Outlook 2013 ?

- Is in cell editing supported on this version

3. Is Microsoft Dynamics CRM 2016 for Outlook compatible with Microsoft  Dynamics CRM Online 2015 Update (7.1.1.4314) (DB 7.1.1.4309)
