Enable calendar overlays across site collections when using HNSC
We've just converted the site collections at a client site from path-based site collections to host-named site collection and discovered that calendar with overlays of calendars from other site collections do not work once we've made the switch to HNSC.
Please enable the ability to use calendar overlays using calendars stored in other host-named site collections. This is an issue with host-named site collections that is disappointing considering Microsoft is recommending the use of HNSC.

Hi, same her. At my school we were able to overlay SP calendars across sitecollections within our SP on premise environement. Now we are using SP Online and O365.
We are no longer able to overlay the calendars anymore which is very annoying.
Please make some effort to correct this.
