I have added my Outlook.com account to my Android (9.1) phone:
Add it as an Exchange Account
As far as I can tell, the Exchange Account method only syncs the primary calendar in my Outlook.com account. I have several other calendars that do not show up on the default Android Calendar App or third part apps like aCalender etc.
As far as the Microsoft Outlook App for Android, I can view all my other Outlook.com calendars.
Is there any solution to sync ALL my Outlook.com calendars with the default Android Calendar app and third part apps?
Is the problem at Microsoft, Google or Huawei?
I hope you can help me and many other people with this annoying issue.
Thank you in advance.
