Organisation Level visibility setting from default free/busy to show meeting titles and locations.

Hi saurabh076

There is no such "general" Setting you have to set it on each Mailbox

###################################################################

# Set Default Calendar Permissions for All Users --> O365 Powershell

####################################################################

Import-Module ExchangeOnlineManagement

Connect-ExchangeOnline

$Mailboxes = Get-EXOMailbox -RecipientTypeDetails UserMailbox -ResultSize Unlimited

 ForEach ($Mailbox in $Mailboxes)

{

$Cal = Get-EXOMailboxFolderStatistics -Identity $Mailbox.PrimarySMTPAddress | Where {$_.Foldertype -eq "Calendar"} | select folderpath

$NormalizedFolder = $Cal.FolderPath.Replace("/","\")

$NormalizedIdentity = $Mailbox.PrimarySMTPAddress + ":" + $NormalizedFolder

Write-Host $NormalizedIdentity -foregroundcolor Green

Set-MailboxFolderPermission -Identity $NormalizedIdentity -user "Default" -AccessRights LimitedDetails -SendNotificationToUser $false 

}

Unless you mean the Hybrid Connection (Mailbox in Exchange Online to Mailbox OnPrem)

Get-OrganizationRelationship -Identity "O365 to On-Prem*" | fl

Set-OrganizationRelationship -Identity "O365 to On-Prem*" -FreeBusyAccessLevel "LimitedDetails"
