Just tested it with my Hotmail account and it works.
But it is not the best way to have it turned on. It can't be turned on via the Calendar at the settings...
How to turn it on:
Settings -> All (accounts) ->Corporate -> Click on the pointer next to your account -> Turn on Calendar
Click on the 3 dots at the bottom and click on Sync Now
Go back to the calendar (check if the new appointments are there).
Click on "More" -> Settings -> Choose which calendars to display -> scroll down and there are a few new calendars from the Hotmail account
Thanks for your answer but I refer to an additional calendar that I have in my gmail acount (shared from a friend and related to some coordinated activities that we have).
In my old phone I could select more than one calendar in my Gmail acount (and in my desktop, with emclient e-mail client for Windows... it is also possible).
If anybody knows how to choose it (in the "choose which calendars to display" it does not appear)... please inform me but I think that it is a bug in MIUI (at least in this version).
... I detected that Whatsapp does not work very well... many times it shows the messages only when I open the App (I suppose that, in background, it dies)... but this is a totally different problem, I know.
I've got the calendar of my favorite soccerteam in my gmail, that worked without even adding it on my Redmi 2.
I have shared my calendar with my wife , so we can both see which appointments we have. But you want it the other way around, that is difficult for me to test
In that case, I still think it is a setting on your phone.
Did it work before you switched to Miui or this phone?
Have you checked all the displayed calenders?
Birthday reminders -unchecked
Local calendar - checked
PSV Calendar - checked
Weeknumbers - checked
My own Google account - checked
Holidays in The Netherlands - checked
Birthdays of contacts - unchecked
Other Google account - unchecked
As test for the Hotmail account, it is all unchecked, because I don't need it anymore:
Hotmail account calendar
I understand you... I saw the list but that one additional (with another name) that I have does not appear in the list ... and and I do not know how to "force" it.
It was there in my old android phone (no MIUI) and my desktop e-mail client (emclient).
I tried to reboot... but no solution, it never shows this other calendar. The calendar is shared to me from another gmail account... probably that is the bug, it is not "mine" it is shared to me from another account. Anyway... MIUI OS should behave right and show it in the list.
