Overlay Room Calendars in Outlook and Sync to SharePoint
This method allows you to combine multiple resource room schedules into a single view in Outlook and optionally publish it to SharePoint for wider team access.
By using the overlay feature in Outlook, you can stack multiple room calendars on top of each other to spot free time slots instantly. If your team needs web access to this schedule, synchronizing it with a SharePoint Calendar app provides a centralized hub.
Open Outlook and navigate to your Calendar view. On the Home tab, click 'Add Calendar' and select 'From Room List'. Browse and add the required resource room calendars to your list.
In the left navigation pane, check the boxes next to the newly added room calendars under 'Shared Calendars'. With the calendars displayed side-by-side, navigate to the 'View' tab, click 'Arrangement', and select 'Overlay' to combine them into one unified view.
To publish this schedule online, log into your SharePoint Online site. Navigate to 'Site Contents', click 'New', select 'App', and choose 'Calendar' to create a new calendar instance.
Open your newly created SharePoint calendar, access the 'Calendar' tab in the ribbon, and click 'Connect to Outlook'. Follow the prompts to sync the SharePoint calendar with your overlaid Outlook view.

Frequently Asked Questions
Can I overlay calendars in the Outlook Web App (OWA)?
Yes, Outlook on the web also supports overlaying calendars. You can add room calendars by searching the directory and they will automatically merge into a combined view when selected together in the sidebar.
Why are some rooms missing from the 'From Room List' option?
If specific rooms are missing, your Exchange Administrator may not have added them to a designated Room List distribution group. Contact your IT department to have the missing resource mailboxes categorized correctly.
Is there a limit to how many calendars I can overlay in Outlook?
Yes, standard desktop versions of Outlook allow you to view up to 30 calendars side-by-side or overlaid in a single view. Exceeding this limit will prompt an error.
Do I need an Outlook account to view the synced SharePoint calendar?
No. Once the combined calendar is successfully published and synced to SharePoint Online, any team member with the appropriate SharePoint site permissions can view the availability directly in their web browser without needing a localized Outlook setup.
