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 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 will try to explain you with my poor English vocabulary, my problem :
I have a PW script to do to activate mailbox archive. When I connect to my local exchange web interface, I see mailboxes with type mailbox attribute is "Office 365". When I try to activate archive on O365, it told me "Your mailbox is synchronized with a local exchange, u have to activate archive on the local exchange ". As I said previously, I see these mailboxes with web interface but when I want to "Get-mailbox" in local one, the result only show me mailboxes with mailbox type "User".
Do you know how I can see my O365 mailboxes with PowerShell on my local exchange?
PS: I already tried to connect to my O365 with ExchangeOnlineManagement and put the "get-mailbox" result in a variable. Then I close my ExchangeOnlineConnection and I did something like this :
$test | enable-Mailbox -Archive
But the answer is always the same : "John DOE doesn't have a mailbox on the local Exchange"
Thanks for advance for your help.
NEW INFO : Someone told me to use "Get-RemoteMailbox" and "Enable-RemoteMailbox". I try this tomorrow and I update the post.
Open the Exchange Management Shell, and then run the following cmdlet:
Enable-RemoteMailbox -Archive
Wait for two cycles of directory synchronization to run (about six hours). Or force directory synchronization. For more info about how to do this, see Synchronize your directories.
Background
Working in a small O365 environment that recently upgraded from E3 to E5.
Issue
The audit log shows that a user enabled DeliverToMailboxAndForward on their mailbox with the Set-Mailbox operation.
Questions
Is PowerShell the only way to issue Set-Mailbox or can it be done
through the GUI somehow?
Is there a way to disable/prevent users from settings this (i.e. do the end users have too many permissions)?
When I query Get-Mailbox user | fl name,forwardingSMTPAddress,delivertomailboxandforward the ForwardingSmtpAddress is empty and DeliverToMailboxAndForward is False. Is this the only way to ensure the action is disabled? Does the disable action appear in any event/audit log?

As an Exchange admin, you can use the Exchange Admin Center (EAC) to go to the Mailbox properties -> Mailbox Features -> Under Mail Flow, select View details -> Check the Enable forwarding, and Browse to the recipient.
Configure email forwarding for a mailbox
Is there a way to disable/prevent users from settings this (i.e. do
the end users have too many permissions)?
From a user perspective they can forward using the Outlook GUI:
Forward email from Office 365 to another email account
When I query Get-Mailbox user | fl name,forwardingSMTPAddress,delivertomailboxandforward the
ForwardingSmtpAddress is empty and DeliverToMailboxAndForward is
False. Is this the only way to ensure the action is disabled? Does the
disable action appear in any event/audit log?
You can use either the PowerShell script to query, or navigate through ECA console to verify. The disable action should appear in the audit if it is set up.
On to the issue,
The audit log shows that a user enabled DeliverToMailboxAndForward on
their mailbox with the Set-Mailbox operation.
Typically most users don't have access to the Exchange Management Console, and the ability to run PowerShell operations. That makes this audit entry "seem" odd. But then digging through the docs I come up to this entry:
Cmdlets that are run directly in the Exchange Management Shell are
audited. In addition, operations performed using the Exchange admin
center (EAC) are also logged because those operations run cmdlets in
the background.
Administrator audit logging in Exchange Server
So what you are likely seeing is an entry that is a GUI running a cmdlet in the background, without the user actually having direct Exchange Management Shell access. As for permissions, I'm not sure about explicit permissions to deny this specific action without denying a lot of other stuff (i.e. it's like denying permissions to forward messages) unless you have a business need to do this.
This question may get a better response in an Office 365 forum, but I'll try to answer your questions:
The GUI/Web UI is executing PowerShell commands on the back end when users change their configuration. In order to be allowed to change a setting in the GUI, the same permission needs to exist for the PowerShell cmdlets.
This permissions is a default included in the MyBaseOptions management role for Office 365 mailbox users. This role includes many other permissions which users require to manage their own mailbox, such as permissions to create inbox rules or update their picture. You can see all the actions included in this role with this command:
Get-ManagementRole -Identity mybaseoptions |Select -Expand roleEntries
The easiest way to audit current mailbox settings is likely running the command as you have done. A more efficient way to query all your mailboxes for just those with specific settings is to use the -Filter parameter on the Get-Mailbox command like this:
Get-Mailbox -Filter {DeliverToMailboxAndForward -eq $true -and ForwardingSMTPAddress -ne $null}
I hope that helps answer your questions!
How can I auto delete Junk E-mail folder Exchange 2010 in OWA if I have Exchange 2010 Standard license and standard license CALs?
Custom retention policy tags won't work because it needs Exchange Enterprise license and CALs.
Currently I use this command, but I need to script the command to delete messages from a specific folder in OWA.
Search-Mailbox -Identity User -SearchQuery "Subject:'*[Spam]' sent:<$("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.
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
