Teams rooms resource account permissions

Hi peely 

Seems like you want do do something like this:

$Room = "room@lab.local"
$Shared = "access@lab.local"
Set-CalendarProcessing -Identity $Room  -ResourceDelegates $Shared -AllBookInPolicy $false -AllRequestInPolicy $true -BookInPolicy @() -ForwardRequestsToDelegates $true -AutomateProcessing AutoAccept
Set-Mailbox -Identity $Room -GrantSendOnBehalfTo $Shared

The Meeting request is forwarded to access@lab.local so you need to add the Permission there

Set(or add)-MailboxFolderPermissions -Identity access@lab.local:\Calendar -User user1@lab.local -AccessRights Editor -SharingPermissionFlags Delegate,CanviewPrivateItems

>Delegate user1@lab.local has full rights to the access@lab.local mailbox
And might also needs the SendAs Permission

Kind Regards
Andres
