Hi H.M_1,
Greetings, regarding the room calendars, if you refer to the calendar of room and equipment mailboxes, then to access the room calendar in Outlook for iOS app, simply follow below steps:
- Sign in to user‘s work account in Outlook for iOS APP: Set up Office apps and email on iOS devices.
- Then tab the Calendar icon > tab the three lines icon in the upper left corner > tab “+” and select "Add a shared calendar".
- Then enter the room/resources mailbox name in the search field to add the room calendar.
Hope above information helps. Please feel free to contact us if there is anything unclear.
