After an initial failed migration from Google Apps to Office 365, I used Powershell to delete all items in the mailbox and start another sync.
Search-Mailbox -Identity "identity" -DeleteContent -force
Search-mailbox -identity "identity" -SearchDumpsterOnly -DeleteContent
Unfortunately, this moved all items into the "Purges" folder and I have not found a way to purge the purges. Since the items reside in purges, I'm not able to synchronize properly between Google Apps.
Ideally, I'd like to completely wipe the mailbox without deleting the user and start over or at least find a way to clear out the purges folder.
Microsoft's best response so far was to wait 30 days until the purges get cleared out....
I did try to set retention to 0 about a day ago with no effect so far:
Set-Mailbox -Identity "mailbox" -RetainDeletedItemsFor 0
For anyone interested, figured out how to remove the purges:
Set retention period to 0:
Set-Mailbox -Identity "identity" -RetainDeletedItemsFor 0
Turn off item recovery:
Set-Mailbox -Identity "identity" -SingleItemRecoveryEnabled $false
Wait > 60 minutes
Run:
Start-ManagedFolderAssistant
This will force retention policy to run and wipe out all emails in purges

Does someone know if it is possible to add a time period to this Powershell command:
Add-MailboxPermission -Identity user01#domain.com -User user02#domain.com -AccessRights FullAccess -InheritanceType All
So is there a way so I can give user02 accessright for the Mailbox of user01 from lets say 2022/11/20 up to 2022/11/25?
No. The Add-MailboxPermission cmdlet does not accept any date-range parameters:
https://learn.microsoft.com/en-us/powershell/module/exchange/add-mailboxpermission?view=exchange-ps
You could write a script to check the current date and run the appropriate Add- and Remove-MailboxPermission commands at the appropriate time.
(An alternate - but messy - approach is to create a temporary user account with access, setting an expiration date on the user account. You'll need to mop up the account and permissions afterwards, though.)
I am trying to delete permissions on a public folder in Exchange Online. We inadvertently desynced mail-enabled security groups in AD-Connect. This caused all permissions to be lost in the migrated public folders (even after resyncing). I've since recreated the security groups in M365 and have the permissions working on the new groups.
However, I am unable to remove the permissions from the folder for any of the synced security groups. If I do it in the GUI it saves without error, but the permission is still there.
In Powershell, I attempt to remove the permission and receive an error of There is no existing permission entry found for user: Finance Group even though the entry shows there is. The Powershell output is below. This is my first post so I am not allowed to embed images yet - apologies.
Get-PublicFolderClientPermission "\Finance\Finance Departmental Calendar"
Powershell Results for Get-PublicFolderClientPermission
Remove-PublicFolderClientPermission -Identity "\Finance\Finance Departmental Calendar" -User "Finance Group"
Powershell Results for Remove-PublicFolderClientPermission
Thanks in advance.
If the issue is not just inheritance, microsoft has some recommendations here: https://learn.microsoft.com/en-us/exchange/troubleshoot/public-folders/public-folder-permission-issues
# check permissions on the primary pf mailbox specifically
Get-PublicFolderClientPermission \puf1 -User User1 -Mailbox (Get-Mailbox -PublicFolder | ?{$_.IsRootPublicFolderMailbox -eq "True"}).Name
# check permissions on the user's pf mailbox
Get-PublicFolderClientPermission "\puf1" -User User1 -Mailbox pubmbx1
# check the hierarchy sync status, and compare between pf mailboxes
$s = Get-PublicFolderMailboxDiagnostics pubmbx1 -IncludeHierarchyInfo
$s.HierarchyInfo
$s.SyncInfo.LastAttemptedSyncTime.LocalTime
$s.SyncInfo.LastFailedSyncTime.LocalTime
$s.SyncInfo.LastSyncFailure
# manually resync permissions to entire pf mailbox
Update-PublicFolderMailbox pubmbx1 -InvokeSynchronizer
Be careful of making changes in O365 if you're in hybrid config. You probably don't want to overwrite the newly-added permissions in O365 by surprise sync up from on-prem
In my anectodal experience, 365 also needs the original user object to exist for some reason. Probably buggy behavior with how it resolves the user name on permission entries. If possible, try and resync the old groups to 365
I have had to export, delete, and recreate a mailbox or publicfolder to fix certain rare situations
i recently moved my exchange server (Windows SBS ;D ). Now i have the Problem that there are some sent mails missing in outlook (only sent mails from May 2020).
I activated the Outlook cache exchange mode already years ago.
With the software Outlookviewer i was able do get all my received emails but i cant find my sent emails from may 2020.
Is there any other way how to recover them ?
Thanks for your help.
To recover deleted mail items in Exchange, an administrator can use Powershell commands and Exchange Admin panel according to understanding and working.
If Administrator wants to try Powershell commands to recover back emails files, then use the command:
Get-Mailbox -ResultSize unlimited -Filter {(RecipientTypeDetails -eq ‘UserMailbox’)} |
Set-Mailbox -SingleItemRecoveryEnabled $true -RetainDeletedItemsFor 30
Before that Enable the recovery of single items with the help of the following command:
Set-Mailbox -Identity “name of the user” -SingleItemRecoveryEnabled $true
Enable the single item recovery and set the retention period of the deleted item for any single user. The following command activates the recovery of the single item and sets the retention period of 30 days.
Set-Mailbox -Identity “name of the user” -SingleItemRecoveryEnabled $true -RetainDeletedItemsFor 30
Since more commands are used so you can refer to the link.
Here you find step by step commands and other precautions that need during recovering deleted items.
I have a PowerShell script which I use to give users local admin permission for their computers, by inputting their username and computer name, which then creates a special AD-group for their computer. I usually remove the group myself in 24 hours.
My question now is, is there any way to have a piece of code scheduled to run in exactly 24 hours and remove the user from the group?
Remove-ADGroupMember -Identity $userName -Member $ADGroup -Confirm:$False
I've done some research about this and found that there are some ways to do this in Windows Server 2016, sadly we're on Windows Server 2012.
Is there some way to create a Task Scheduler event for the specific user being removed from the group?
Any ideas?
Start-Sleep -Seconds 86400
https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/start-sleep?view=powershell-6
might not be best practices.
why not have a script that runs every day on your server that remove members from the group where their last modified date is greater than 24hrs ?
You can create a script that would dynamically generate a scheduled task to run another script that would do the removal.
https://learn.microsoft.com/en-us/powershell/module/scheduledtasks/new-scheduledtask
The trigger would need to be set for 24 hours in the future, as opposed to logon in the example, but otherwise it should be straight forward.
Also, I would recommend setting the removal script to accept the user's username as a parameter.
How can I auto delete Junk E-mail folder Exchange 2010 in OWA if I have Exchange 2010 Standard license and standard license CALs?
Custom retention policy tags won't work because it needs Exchange Enterprise license and CALs.
Currently I use this command, but I need to script the command to delete messages from a specific folder in OWA.
Search-Mailbox -Identity User -SearchQuery "Subject:'*[Spam]' sent:<$("10.06.2016")" -Delet
eContent -confirm:$false
You can use Get-Mailbox to pass mailbox identities to the Search-Mailbox command similar to the way described in this question. Ex:
Get-Mailbox -ResultSize Unlimited | Search-Mailbox -SearchQuery "Subject:'*[Spam]' sent:<$("10.06.2016")" -LogOnly -LogLevel Full
There are a few things to keep in mind when using Search-Mailbox this way. It can't search JUST the spam folder, so test your queries using the -LogOnly switch. You may want to further limit the kind of mailboxes retrieved by using -RecipientTypeDetails to retrieve only UserMailbox types. Regardless of what you're trying to delete, be sure you are getting only the results you want from your query before pulling the trigger on -DeleteContent.
