Removing the "Use a Meeting Workspace" Option from All Existing and New SharePoint Calendars in a Site Collection

Having removed the "Use a Meeting Workspace" option from individual calendars in my previous post, I wondered if there was a way to remove them from all existing and new calendars within a site collection.

I found a way to do it by modifying the calendar schema in the hive folder. However, although this works, it technically leaves SharePoint in an unsupported state, so I didn’t want to go down that route.

Then I had a thought that all the items in a calendar list are of the Event content type, so if you can modify that, to make the Workspace option hidden, then it would be removed from all calendars.

Unfortunately when you look at the Event Content Type in the Site Content Types gallery, the Workspace column is greyed out so you can’t edit it.


However, it proved to be remarkably easy to script using PowerShell:

# Script to remove Use a Meeting Workspace from all calendars
$siteUrl = "http://myserver/sites/mysite"
[system.reflection.assembly]::LoadWithPartialName("Microsoft.Sharepoint") > $null
$site = New-Object Microsoft.SharePoint.SPSite($siteUrl)

$contentTypeId = [Microsoft.SharePoint.SPBuiltInContentTypeId]::Event
$eventContentType = $site.RootWeb.ContentTypes[$contentTypeId]

$fieldId = [Microsoft.SharePoint.SPBuiltInFieldId]::WorkspaceLink
$field = $eventContentType.FieldLinks[$fieldId]

$field.Hidden = $true

# Dispose the site object
if ($site) {$site.Dispose()}

The only slightly tricky bit was needing to use the FieldLinks property instead of Fields.

The $eventContentType.Update($true); line ensures that it updates all existing calendars in the site collection, otherwise it will just be for new ones.

I’ve actually increased the script by 2 lines to fit it in my blog by adding in the $fieldId and $contentTypeId. Originally it was even more compact.

Again, this takes effect immediately throughout the entire site collection with no need for an iisreset or an application pool recycle.

Using PowerShell to Remove the "Use a Meeting Workspace" Option from SharePoint Calendars

I’ve just deployed a custom meeting site to a customer to handle multiple meetings within one site. Hence the option to “Use a Meeting Workspace” when creating a new or updating a calendar item is unnecessary, so they asked me to remove it to prevent anyone using it by mistake.

When creating a calendar item (or updating) this is the dialog you get, with the Use a Meeting Workspace highlighted.


From SharePoint Blues I discovered that if you set the calendar list field to hidden then this option would no longer display. Taking this concept, I created a PowerShell script to set this to hidden on a one off basis.

The script is:

# Script to remove Use a Meeting Workspace from a specific calendar

function RemoveWorkspaceLink ([String]$siteUrl, [String]$calendarName)
[system.reflection.assembly]::LoadWithPartialName(“Microsoft.Sharepoint”) > $null
$site = New-Object Microsoft.SharePoint.SPSite($siteUrl)
if ($site -eq $null)

$web = $site.OpenWeb()
$list = $web.Lists[$calendarName]
if ($list -eq $null)
“Invalid list name ” + $calendarName
$field = $list.Fields[[Microsoft.SharePoint.SPBuiltInFieldId]::WorkspaceLink]
$field.Hidden = $true
“Updated ” + $calendarName + ” on ” + $siteUrl

# Dispose of the SharePoint objects
if ($web) {$web.Dispose()}
if ($site) {$site.Dispose()}

RemoveWorkspaceLink “http://myserver/sites/site1″ “Calendar1”
RemoveWorkspaceLink “http://myserver/sites/site2″ “Calendar2”

I’ve written this as a function so that you can update multiple calendars at the time. If you saved this as a .ps1 file and then run it, the 2 calendars referenced at the bottom would be updated. Alternatively you could . source the file and use the function interactively, or just hard code the $siteUrl and $calendarName variables each time you run it.

The option is removed immediately you have run the script with no iisreset or application pool recycle required.

So with the script is run this is what you see with the Meeting Workspace option removed:


This works well for hiding it on individual calendar lists, but doesn’t affect any other existing calendars or ones created afterwards.

I’ve since found a way to update all calendars in a site collection.
