Exchange 2013 this cmdlet no longer exists but the same problem persists: disconnected mailboxes are not visible immediately after being removed or disabled…. Clean-MailboxDatabase has been replaced by Update-StoreMailboxState, which forces the mailbox store state in the Exchange store to be synchronized with Active Directory.

Its syntax is as follows:

Update-StoreMailboxState -Database “DatabaseIdParameter” -Identity “StoreMailboxIdParameter” [-Confirm [SwitchParameter]] [-WhatIf [SwitchParameter]]

Both the –Database and –Identity parameters are required, meaning we need to know the identity of the mailbox (mailbox GUID) that we want to update the store state for. To do so, we can run the following cmdlet for example:

Get-MailboxDatabase | Get-MailboxStatistics | Format-List DisplayName, MailboxGuid, Database, DisconnectReason, DisconnectDate

Once we know the mailbox’s GUID and in which database it was located, we can update its mailbox state by running:

Update-StoreMailboxState -Database “db_name” -Identity “mailbox_guid”

If we want to update the mailbox state for all mailboxes on a particular database, we can adapt the cmdlet to:

Get-MailboxStatistics -Database “db_name” | ForEach {Update-StoreMailboxState -Database $_.Database -Identity $_.MailboxGuid -Confirm:$False}

Finally, if we want to just update the mailbox state for all disconnected mailboxes on a particular database:

Get-MailboxStatistics -Database “db_name” | Where {$_.DisconnectReason -ne $null } | ForEach { Update-StoreMailboxState -Database $_.Database -Identity $_.MailboxGuid -Confirm:$False}

 

Scenario: You want to find who has delegate permissions to a mailbox and export the users, folders, and access permissions to a CSV File.

Run the following:

$AllUsers = get-mailbox  test*

ForEach ($Alias in $AllUsers)
 {
 $Mailbox = “” + $Alias.Name
 Write-Host “Getting folders for mailbox: ” $Mailbox
 $Folders = Get-MailboxFolderStatistics $Mailbox | % {$_.folderpath} | % {$_.replace(“/”,””)}

 $list = ForEach ($F in $Folders)
  {
  $FolderKey = $Mailbox + “:” + $F
  $Permissions = Get-MailboxFolderPermission -identity $FolderKey -ErrorAction SilentlyContinue
  $Permissions | Where-Object {$_.User -notlike “Default” -and $_.User -notlike “Anonymous” -and $_.AccessRights -notlike “None” -and $_.AccessRights -notlike  “Owner” }| Select $Mailbox, User, FolderName, AccessRights, *path*
  }
 }

$list | Export-csv C:delegates.csv

Scenario:  When you attempt to remove a mobile device from a users mailbox, you receive the error below.

Error:  An unexpected error has occurred and a Watson dump is being generated: DeviceId cannot contain hyphens.  

Resolution: Remove the mobile device object via ADSI Edit.

1. Open ADSI Edit.
2. Under the Default Naming Context, navigate to the user object of the mailbox that has the mobile device.
3. Expand that user object, and click on the CN=ExchangeActiveSyncDevices.
4. Delete the Mobile Device for this user.

Task: Retrieve all mailboxes assigned to a specific ActiveSyncMailboxPolicy.  The ActiveSyncMailboxPolicy we are searching for is labeled “VIP”.

Run the following:

Get-CASMailbox -ResultSize unlimited | Where ActiveSyncMailboxPolicy -like “VIP” | Select SamAccountName, DisplayName,ActivesyncMailboxPolicy,ServerName | Export-csv C:VIP_EASPolicy.csv
