    Cannot Delete Emails from Deleted Items Folder in Office 365 Mailbox

    May 10, 2025

    This issue could be due to the retention policies but this could also be caused by litigation hold, eDiscovery case hold. Before proceeding verify the quota is exceeding by running below command

    Get-MailboxStatistics -identity <PrimarySMTPAddress> -folderscope recoverableitems | format-table name, folderandsubfoldersize, itemsinfolderandsybfolders -auto

    Verify the storage utilization by the “RecoveryItem” folder, A regular mailbox will have a max size of 30 GB and 100 GB for the mailbox that has litigation hold.

    We need to make sure to disable deleted item retention and single item recovery for the mailbox until the issue is fixed by executing below commands:

    Set-Mailbox <PrimarySMTPAddress> -RetainDeletedItemsFor 0
    Set-Mailbox <PrimarySMTPAddress> -SingleItemRecoveryEnabled $false

    Once the above steps are completed and verified, continue with below commands.

    Get-mailbox -identity <Mailbox> | Select-Object ElcProcessingDisabled.

    Set-Mailbox -identity <Mailbox> -ElcProcessingDisabled $False

    Start-ManagedFolderAssistant <Mailbox> -Fullcrawl

    Wait for 15 mins

    Start-Managefolderassistant <Mailbox> -holdcleanup

    Wait for 1 hour and then execute the below command:

    Start-ManagedFolderAssistant <Mailbox>

    After the issue is fixed execute the below commands to re-apply the settings

    Set-Mailbox <PrimarySMTPAddress> -RetainDeletedItemsFor 14
    Set-Mailbox <PrimarySMTPAddress> -SingleItemRecoveryEnabled $true
    Start-ManagedFolderAssistant -Identity <PrimarySMTPAddress>

     

    You will notice the mailbox recovery in about next 30-60 Mins.

    Thanks,
    WintelAdmin
