Outlook Calendar.com, Outlook 2016, Shared calendars

Dear Spice & I have Outlook.com accounts (both updated), with calendars shared with each other on Outlook.com (co-owner access level).

We can update each other's calendar directly on Outlook.com and in W10 Calendar. However, despite being configured as Exchange ActiveSync accounts, Outlook 2016 (and Outlook for Android) will only allow view-only access!

O16 is saying that "You do not have authorization to make changes to this folder."

This seems to require direct access to an Exchange server to change the folder configuration, for an EAS connection. *Confused

If Outlook.com is an Outlook 365 service running EAS, how can we tell Outlook 2016 to permit the full sharing access as authorized on Outlook Calendar.com?

This is probably affecting a lot of personal users who can't afford the infrastructure to run their own Exchange servers, just to share calendars.

(We are some of the refugees from Windows Live Mail, orphaned by the Outlook 365 conversion. That's why we're trying both O16 and Outlook for Android -- our eventual goal is to enable updating each other's calendars from our Android phones.)

 

Outlook Calendar.com, Outlook 2016, Shared calendars

When you setup an outlook.com email account in Outlook 2013 or 2016 automatically, it will be set up as MAPI / Microsoft Exchange account and you will only be able to view calendars shared with you.

To be able to edit calendars shared with you, you have to select manual setup when adding an outlook.com account and select Exchange ActiveSync:




The Exchange ActiveSync server for all outlook.com / hotmail.com / msn.com / live.com email addresses is eas.outlook.com:



Now you will be able to edit shared calendars.

If and when an email account is already set up in Outlook as Microsoft Exchange, it cannot be converted to Exchange ActiveSync. You need to remove the account from Outlook and add it again selecting manual setup and Exchange ActiveSync.
