# Exchange PowerShell - Publish Room / Equipment Calendars


So you've got some resource (rooms/equipment) calendars in Exchange that you need to make the calendars public for. You can use PowerShell to accomplish this quite easily.

First of all you can get the current calendar publishing information by using the **[Get-MailboxCalendarFolder](https://docs.microsoft.com/en-us/powershell/module/exchange/mailboxes/get-mailboxcalendarfolder?view=exchange-ps)** cmdlet:

```powershell
Get-MailboxCalendarFolder -Identity VIRT-V01:\\Calendar
```

Note that if the mailbox's language is not English (GB/US/etc) then you will need to change the **:\\Calendar** suffix to the relevant one.

All the relevant calendar publishing information is then displayed:

```
RunspaceId                      : 2a27a1b5-42d1-4700-bd25-713b4892d960
Identity                        : VIRT - V.01 (10):\\Calendar
PublishEnabled                  : False
PublishDateRangeFrom            : SixMonths
PublishDateRangeTo              : SixMonths
DetailLevel                     : FullDetails
SearchableUrlEnabled            : False
PublishedCalendarUrl            :
PublishedICalUrl                :
ExtendedFolderFlags             : SharedOut, SharedViaExchange, ExchangeShareFolder, ExchangePublishedCalendar
ExtendedFolderFlags2            :
CalendarSharingFolderFlags      : None
CalendarSharingOwnerSmtpAddress :
CalendarSharingPermissionLevel  : Null
SharingLevelOfDetails           : None
SharingPermissionFlags          : None
SharingOwnerRemoteFolderId      : AAA=
LastAttemptedSyncTime           : 01/02/0001 00:00:00
LastSuccessfulSyncTime          : 01/02/0001 00:00:00
CreationTime                    : 02/11/2019 08:07:31
DelegateInformation             : Delegate Information was not calculated.
DefaultOnlineMeetingProvider    : TeamsForBusiness
AllowedOnlineMeetingProviders   : {TeamsForBusiness}
IsValid                         : True
ObjectState                     : Changed
```

You can see that publishing is disabled (PublishEnabled = false) and that the calendar url (PublishedCalendarUrl) and iCal (PublishedICalUrl) feed are empty.

To **enable publishing** you need to use the **[Set-MailboxCalendarFolder](https://docs.microsoft.com/en-us/powershell/module/exchange/mailboxes/set-mailboxcalendarfolder?view=exchange-ps)** cmdlet.

```powershell
Set-MailboxCalendarFolder -Identity VIRT-V01:\\Calendar -PublishEnabled $true -DetailLevel Full -PublishDateRangeFrom SixMonths -PublishDateRangeTo SixMonths
```

This will publish the calendar and make the past and future six months of events visible with full information available. You can execute the **Get-MailboxCalendarFolder** cmdlet again to retrieve the urls.

PublishedCalendarUrl : https://outlook.office365.com/owa/calendar/cecc3ccb3ba64d6fa3a4dc9c98d6122c@resources.test.com/51c0f0ee990d4428833b9fd521fa4f6217934636036240388081/calendar.html
PublishedICalUrl : https://outlook.office365.com/owa/calendar/cecc3ccb3ba64d6fa3a4dc9c98d6122c@resources.test.com/51c0f0ee990d4428833b9fd521fa4f6217934636036240388081/calendar.ics

If you decide to disable publishing, you can just execute the following:

```powershell
Set-MailboxCalendarFolder -Identity VIRT-V01:\\Calendar -PublishEnabled $false -ResetUrl
```

The **ResetUrl** switch will clear the url properties. This is entirely optional. If you decide to enable publishing again then new urls may be generated if ResetUrl was specified.
