Here are some commands to use to manage Dedicated Room mailboxes.

Dedicated Rooms can also be scheduled by some restricted people.

Getting delegates list :

$GetDelegates=(Get-MailboxCalendarSettings “$Room”).ResourceDelegates

Setting Delegates :

$Mbx=Get-Mailbox “$Room”

$Mbx|Set-MailboxCalendarSettings -ResourceDelegate $Delegates

$Delegates is an Array value

Remove a delegate :

$Mbx=Get-Mailbox “$Room”

$delDelegate <- SAM of the delegate to remove

$NewDelegates=($Mbx|

Get-ADPermission |

Where-Object {-not $_.isinherited} |

Where-Object {$_.user -match “^DOMAIN”}|

ForEach-Object {

If(($_.User.ToString().split(“/”)[1]) –ne $delDelegate){

$_.User.ToString().split(“/”)[1]

}

}

)

$Mbx|Set-MailboxCalendarSettings -ResourceDelegate $NewDelegates

Add a delegate :

$Mbx=Get-Mailbox “$Room”

$DelegateToAdd <- SAM of the delegate to add

$NewDelegates=($Mbx|

Get-ADPermission |

Where-Object {-not $_.isinherited} |

Where-Object {$_.user -match “^DOMAIN”}|

ForEach-Object {

If(($_.User.ToString().split(“/”)[1]) –ne $delDelegate){

$_.User.ToString().split(“/”)[1]

}

}

)

$NewDelegates += $DelegateToAdd

$Mbx|Set-MailboxCalendarSettings -ResourceDelegate $NewDelegates

Get a manager of a dedicated room :

$Mbx=Get-Mailbox “$Room”

$Manager=(get-user $Mbx).Manager

 Modify a Manager :

Function Remove_Old_Mgr ([string]$Upn, [string]$Nom, [string]$Responsible ) {

$domainResponsible=$RespDomain + ” + $Responsible

Remove-MailboxPermission -Identity $UPN `

-AccessRights FullAccess `

-User $Responsible `

-DomainController $Controller

Remove-ADPermission -Identity “$($Nom)” `

-AccessRights ReadProperty `

-User $DOMAINResponsible `

-DomainController $Controller

Remove-ADPermission -Identity “$($Nom)” `

-AccessRights WriteProperty `

-User $DOMAINResponsible `

-DomainController $Controller

}

Function Set_New_Mgr ([string]$Upn, [string]$Nom, [string]$Responsible) {

$DOMAINResponsible=$RespDomain + ” + $Responsible

Add-MailboxPermission -Identity $UPN `

-AccessRights FullAccess `

-User $Responsible `

-DomainController $Controller

Add-ADPermission -Identity “$($Nom)” `

-AccessRights ReadProperty `

-User $DOMAINResponsible `

-DomainController $Controller

Add-ADPermission -Identity “$($Nom)” `

-AccessRights WriteProperty `

-User $DOMAINResponsible `

-DomainController $Controller

}

$Mbx=Get-Mailbox “$Room”

remove_old_mgr $Mbx.UserPrincipalName $Mbx.Name $Manager

$Mbx | Set-User -Manager $NewManager

set_new_mgr $Mbx.UserPrincipalName $Mbx.Name $NewManager
