I have a Calendar that needs to be shared to 5 users (and eventually more in the future) that will be accessed almost exclusively from their mobile devices (assorted Android and iOS devices). The problem is that after doing extensive research it seems that the native clients for both Android and iOS don't support Shared Exchange Calendars, only the Default Calendars.



I tried doing some research into 3rd party mail/calendar clients but none of them specify this as a feature so I can't know for sure without going through them one by one. Which I'm willing to do if it's necessary but I'm hoping one of you may have some specifics that will save me time. But I'm open to any and all solutions to this problem, not just 3rd party clients.

Here are my parameters though:
-I need some users have read/write access and some users have read-only access
-The calendar needs to be viewable from Android/iOS phones and PCs

Thank you.
