When you delete a public folder using a legacy Outlook client, you can easily restore the deleted folder and it's content using the Recover Deleted Items function.
Due to a fancy trick implemented in Outlook 2013 and Outlook 2016 the recovered folder will not be recovered using it's full name.
This phenomenon has been verified with Exchange On-Premises and Exchange Online on the server side and Outlook 2013/2016 and Outlook 365 ProPlus.
The following example uses public folders in Exchange Online and Outlook 365 ProPlus.
In this example I will delete and recover a public folder named My Public Folder.
After deletion of My Public Folder and it's content, I need to select the original parent folder and click the Recover Deleted Items button in the button bar.
The Recover Deleted Items dialogue opens and we select the deleted item for recovery. The dialogue displays the original name of the deleted folder.
After recovering the deleted folder the folder is recovered with the first character only.
That's an annoying result in regards to customer self-care when users restore deleted items on their own behalf.
But wait, there is a solution available.
The solution requires today's primary administrative tool available: PowerShell.
Get an overview of public folders currently located in the public folder dumpster
Get-PublicFolder –Identity “\NON_IPM_SUBTREE” –Recurse Name Parent Path ---- ----------- NON_IPM_SUBTREE [...] My Public Folder \NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-3... Sub Folder 1 \NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-3... Sub Folder 2 \NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-3... [...]
Export the list of public folders currently located in the public folder dumpster and find the identity of the deleted public folder you want to recover
Get-PublicFolder –Identity “\NON_IPM_SUBTREE” –Recurse | fl | Out-File D:\TMP\publicfolderdumpster.txt
publicfolderdumpster.txt excerpt:
RunspaceId : 6ce9588e-829b-4592-aedc-85f9a2e2c963 Identity : \NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-366a-4e0 9-81fe-ea576ec7a6f7\My Public Folder Name : My Public Folder MailEnabled : False MailRecipientGuid : ParentPath : \NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-366a-4e0 9-81fe-ea576ec7a6f7
Recover the deleted public folder to the correct parent target folder
Set-PublicFolder –Identity "\NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-366a-4e09-81fe-ea576ec7a6f7\My Public Folder" –Path “\TestFolders” –Verbose
As a result the public folder is recovered with it's original name.
There are some other things to consider when recovering deleted modern public folders.
Public folders originally located in the hierarchy root are always recovered to the public folder mailbox holding the primary hierarchy.
Public folders originally located in the hierarchy root will replace the permissions of child public folders when restored.
More on these default restore behaviours can be read here.
Nevertheless, enjoy modern public folders.
You can block an user from logging on to Office 365 by setting the BlockCredential attribute to $true.
Set-MsolUser -UserPrincipalName myuser@mcsmemail.de -BlockCredential $true
But the MSOL user attribute is reverted to $false, when ADD Connect synchonization cycle runs.
This happens, because the local Active Directory attribute accountEnabled is used to controll the BlockCredential attribute in Azure AD.
If your IT operation requires the ability to have enabled users in your local Active Directory infrastructure and you need to prevent logon to cloud services you need to prevent the accountEnabled attribute from being synchronized to Azure AD. This might not necessarily be a general requirement during normal operations, but might be useful while doing a Proof-of-Concept.
Just exclude the attribute from the Azure Active Directory connector in the Synchronization Service Manager.
The following script disables all users excluding
# Userfilter $UserExceptions = ("Sync_SYNC01_add98768492f@mcsmemail.onmicrosoft.com","SPO-SRV-ACCOUNT@mcsmemail.de","SynchedAdmin@mcsmemail.de") # Fetch synchronized users $DomainAccounts = Get-MsolUser -EnabledFilter EnabledOnly -MaxResults 5000 | Where-Object -Property LastDirSyncTime -ne $null # Select synchronized users not following the pattern ADM*@mcsmemail.de (admin accounts in this case) $DomainAccountsWithoutAdmins = $DomainAccounts | Where-Object -Property UserPrincipalName -notlike "ADM*@mcsmemail.de" # Exclude accounts listed in $UserExceptions $DomainAccountsWithoutAdminsFiltered = $DomainAccountsWithoutAdmins | Where-Object -Property UserPrincipalName -NotIn $UserExceptions # Now block cloud logon for all filtered users ForEach ($User2Block in $DomainAccountsWithoutAdminsFiltered) { Write-Host ('Disabling User: {0}.UserPrincipalName)' -f $User2Block) Set-MsolUser -UserPrincipalName $User2Block.UserPrincipalName -BlockCredential $true }
Enjoy Office 365.
The PowerShell module GlobalFunctions got updated to Version 2.0. This module is used by some of my PowerShell scripts which utilize centralized logging.
The new release contains the first functions required for some upcoming scripts for managing on-boarding process for joiners and the off-boarding process for leavers for companies utilizing Office 365.
The New-RandomPassword functions is based on Simon Wahlin's script published here: https://gallery.technet.microsoft.com/scriptcenter/Generate-a-random-and-5c879ed5
This script has been developed for a custom project with the following requirements:
The script utilizes a self developed C# command line tool, which has been published as open source at Github. The ResizeImage Wiki explains the usage of the command line tool. The application's configuration controls the target size and an optional pixel based offset.
Maybe the script will be useful in your project as well.
The code samples utilize the following folder structure:
# EXAMPLE # Resize photos stored in the default PictureSource folder for Exchange On-Premises (648x648) and write images to user mailboxes .\Set-UserPictures.ps1 -ExchangeOnPrem # EXAMPLE # Resize photos stored on a SRV01 share for Exchange Online and save resized photos on a SRV02 share .\Set-UserPictures.ps1 -ExchangeOnline -PictureSource '\\SRV01\HRShare\Photos' -TargetPathExchange '\\SRV02\ExScripts\Photos' # EXAMPLE # Resize photos stored in the default PictureSource folder for Active Directory (96x96) and write images to user thumbnailPhoto attribute .\Set-UserPictures.ps1 -ActiveDirectory # EXAMPLE # Resize photos stored in the default PictureSource folder for Intranet (150x150) .\Set-UserPictures.ps1 -Intranet
Using this script you can test the domain availability in Office 365 and Azure AD. As there are different closed Office 365 and Azure AD regions you need to test per dedicated closed Office 365 region.
Regions currently implemented:
The script queries the login uri for the selected Office 365 region.
The response contains metadata about the domain queried. If the domain already exists in the specified region the metadata contains information if the domain is verified and/or federated.
Load function into your current PowerShell session:
. .\Test-DomainAvailability.ps1
# EXAMPLE # Test domain availability in the default region - Office 365 Global Test-DomainAvailability -DomainName example.com # EXAMPLE # Test domain availability in Office 365 China Test-DomainAvailability -DomainName example.com -LookupRegion China
