Share Users Folder from Mailbox in Office 365 with Powershell EXO

Question

Dear Ladies and Gentleman

Iam Trying to complete my task with the following code and situation.

A user has a lot of folders in his mailbox. Some of them should be shared with other users from the same domain.

With the actual code which should work, i actually don`t get the goal. I also don't get any Errors in Powershell ISE.

But the Permission will ne be set.

Does somebody can help me in this situation?

$requiredfoldertypes = @("Posteingang_LOKAL\DLR","Posteingang_LOKAL\Eisele Carport Esslingen","Posteingang_LOKAL\Gewürz Mayer","Posteingang_LOKAL\Regner Klinikum St. Marien Amberg ")

$excludedfoldertypes = @()

$accessright = “Reviewer"

$users = @("Kretschmer@contoso") #,"******@contoso.com")

$mbx = Get-EXOMailbox -Identity ******@contoso.com | Select-Object PrimarySmtpAddress

$folderlist  = Get-EXOMailboxFolderStatistics -Identity $mbx.PrimarySmtpAddress | Select-Object Name, FolderPath, FolderType, Identity | ?{($_.FolderType -in $requiredfoldertypes) -and ($_.FolderType -notin $requiredfoldertypes) }

 

#Then we can use either Add-MailboxFolderPermission to assign or Set-MailboxFolderPermission to modify.

foreach($user in $users)

{

    $u = Get-EXOMailbox -Identity $user | Select-Object PrimarySmtpAddress

    foreach($folder in $folderlist)

    {

        if($folder.FolderType -eq "Root") {$foldername = $mbx }

        else {$foldername = $folder.Identity.ToString().Replace([char]63743,"/").Replace($mbx.PrimarySmtpAddress.ToString(),$mbx.PrimarySmtpAddress.ToString() + ":")}

        $foldername

        Add-MailboxFolderPermission -Identity $foldername -User $u.PrimarySmtpAddress.Tostring() -AccessRights $accessright

        Get-MailboxFolderPermission -Identity $foldername -User $u.PrimarySmtpAddress.Tostring()

    }

}

Oviously the follow command works like a charm but without inheritance.

$mailbox = "******@contos.com"

$user = "******@comtoso.com"  $foldername = "Posteingang_LOKAL\AMG Erweiterung Vormontage LZM-Marbach"

$folder = (Get-EXOMailboxFolderStatistics -Identity "$($mailbox)" | Where-Object { $_.FolderType -eq "Posteingang_LOKAL" }).Name

Add-MailboxFolderPermission "$($mailbox):$($folder)\$($foldername)" -User "$($user)" -AccessRights "Reviewer" | Select-Object FolderName, User, AccessRights

Maybe somebody had already the problem and could help me?

Kind Reagrds.

What exactly is the Posteingang_LOKAL folder? You cannot use the cmdlet to grant permissions to any local folder (i.e. ones exposed from an opened PST), if that's what you are after.

If you want to run this only for subfolders of a specific folder, use the -ParentFolderPath parameter as explained in: https://www.michev.info/blog/post/5763/managing-mailbox-folder-permissions-in-bulk-in-microsoft-365
