Office 365 – How to Publish a Room Calendar
posted by Phi-lac Nguyen
on Nov 06, 2018
The purpose of this article is to explain how to publish a room calendar using Microsoft Exchange Online with PowerShell. Following these instructions and making room calendars available for everyone to view on the intranet can make it easier to book a meeting room.
By default, a room calendar is not published. A user can get access to it by adding it from Outlook:
It is not convenient to manage room calendars the “classic” way, as it makes it difficult to tell when a room is available. If a company has 10 meeting rooms to manage, it is preferable to have a view for all of the room calendars.
Here are the steps to follow to publish a room calendar:
1. Connect to Exchange Online:
In order to connect to Exchange Online with Powershell, the following script needs to be run:
$UserCredential = Get-Credential
$Session = New-PSSession –ConfigurationName Microsoft.Exchange –ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic –AllowRedirection
Import-PSSession $Session –DisableNameChecking
2. Publish The Room Calendar:
Set-MailboxCalendarFolder -Identity [email protected]:\calendar -PublishEnabled $true
You can verify if the command works by executing this command:
Get-MailboxCalendarFolder -Identity [email protected]:\calendar
3. Enable More Details:
This step is required to get the URL of the calendar:
Get-MailboxCalendarFolder -Identity [email protected]:\calendar -DetailLevel Full
4. Get The URL of The Room Calendar:
Get-MailboxCalendarFolder -Identity [email protected]:\calendar
The URL should appear as in the below screenshot:

Great
quick question @PhiLac:
– After public, everyone have permission access Sharepoint can access Room Calendar ? even user have no permission of Exchange online ?
– is it readonly calendar right ?
The calendar becomes public and accessible for everyone in read only.
Thanks so much for these instructions! This was a big help. There is one small mistake in Step 3. It should say “Set-MailboxCalendarFolder” instead of “Get-…”
Also it maybe helpful to show the other options instead of just FullDetails – they’re listed here:
https://docs.microsoft.com/en-us/powershell/module/exchange/mailboxes/set-mailboxcalendarfolder?view=exchange-ps
The options are AvailabilityOnly, LimitedDetails or FullDetails.
Plus we can use Powershell to change how far in advance the calendar items are published. It defaults to just ThreeMonths. I changed this to OneYear.
Your article definitely pointed me in the right direction. Thanks!
Hello, thanks for the info. However I get HTTP ERROR 403 when I try to access to public URL. What have I missed? I have done all the above steps.
Hi Kalle,
Thank you for leaving a comment on this blog
The link needs to have the value:
-PublishEnabled $true
You can check by using the following command:
Get-MailboxCalendarFolder -Identity [email protected]:\calendar

Hello, Thanks very much for the article it’s quite helpfull. I am trying to get a way to do a Rooms reservation from outside of the organization. Is there any way to that I don’t know may be with sharepoint, could it be?
Thanks again for some help

Great instructions, thanks!
When I access the published calendar in a web browser, all appointments are showing as UTC, rather than PDT as in Outlook. Is there a setting I can change in powershell to resolve this? Thanks, Richard
