Name must be unique per owning mailbox. There’s already a request with the name

While migrating some public folders to Office 365 Groups, I kept running into issues with one of the target groups:

“De gebruiker XXX heeft al een aanvraag die in behandeling is. Verwijder de bestaande aanvraag en hervat de huidige batch of start een nieuwe batch voor deze gebruiker. –> Name must be unique per owning mailbox. T”

In english you’ll probably see “Name must be unique per owning mailbox. There’s already a request with the name “.

I figured there was a moverequest hanging / not properly cleaned up; but none to be found with get-moverequest, get-migrationuser or get-migrationbatch; all clean!

In the end, it took almost 2 weeks of patience after contacting support until the Exchange Online backend team reset a hanging job on their end. So if you google above errors and come here, check if you have double jobs, if you don’t, request support and make sure they escalate to the product team immediately.

portal.microsoftonline.com down (fixed)

It seems portal.microsoftonline.com is down, this may affect OnedriveMapper users, some tenants seem to get redirected during the logon process to portal.microsoftonline.com, but many also don’t. If you’re affected, open a ticket with Microsoft.

OnedriveMapper will show this in the log: | ERROR | Error detected while following redirect, check the FAQ for help

Update: it seems only ADFS / federated tenants are affected.

Update: the RPT update command seems to have fixed the issue for most of those affected.

OnedriveMapper v3.14 released!

Version 3.14 of OneDriveMapper has been released:

  • added an ‘always reset IE cookies’ option
  • completely revamped the way you configure mappings (make sure you read the help in the code!)
  • optionally, map to Network Locations instead of Driveletters (thanks Tom!)
  • Most options are no longer mandatory
  • OnedriveMapper Cloud no longer supported (as announced last year)
  • New and greatly enhanced Folder Redirection functions, including automatic copying of source content
  • Optional client certificate selection based on certificate template name
  • Automatic certificate refresh if no client certificate is present, when using client certificates as auth mode
  • Some bugfixes and major code cleanup
  • Usage of environment variable to determine mapping driveletter removed

As always, make sure to test before deploying to production, I’ve only tested Azure AD and a single ADFS setup.

set Intune MDM user scope to ALL using Powershell and hidden API

If you want to change the settings on this page (or most Azure Portal pages) programmatically:

Microsoft’ll tell you to use your browser, there is no API/PS for this yet. As I really hate the answer “no”, I used Fiddler and baked some Powershell:


login-azurermaccount
$context = Get-AzureRmContext
$tenantId = $context.Tenant.Id
$refreshToken = $context.TokenCache.ReadItems().RefreshToken
$body = "grant_type=refresh_token&refresh_token=$($refreshToken)&resource=74658136-14ec-4630-ad9b-26e160ff0fc6"
$apiToken = Invoke-RestMethod "https://login.windows.net/$tenantId/oauth2/token" -Method POST -Body $body -ContentType 'application/x-www-form-urlencoded'

$header = @{
'Authorization' = 'Bearer ' + $apiToken.access_token
'Content-Type' = 'application/json'}
$url = "https://main.iam.ad.ext.azure.com/api/MdmApplications/eab0bcaf-9b2e-4e62-b9be-2eea708422f8?mdmAppliesToChanged=true&mamAppliesToChanged=true"

$content = '{"objectId":"eab0bcaf-9b2e-4e62-b9be-2eea708422f8","appId":"0000000a-0000-0000-c000-000000000000","appDisplayName":"Microsoft Intune","appCategory":null,"logoUrl":null,"isOnPrem":false,"appData":{"mamEnrollmentUrl":null,"mamComplianceUrl":null,"mamTermsOfUseUrl":null,"enrollmentUrl":"https://enrollment.manage.microsoft.com/enrollmentserver/discovery.svc","complianceUrl":"https://portal.manage.microsoft.com/?portalAction=Compliance","termsOfUseUrl":"https://portal.manage.microsoft.com/TermsofUse.aspx"},"originalAppData":{"mamEnrollmentUrl":"https://wip.mam.manage.microsoft.com/Enroll","mamComplianceUrl":"","mamTermsOfUseUrl":"","enrollmentUrl":"https://enrollment.manage.microsoft.com/enrollmentserver/discovery.svc","complianceUrl":"https://portal.manage.microsoft.com/?portalAction=Compliance","termsOfUseUrl":"https://portal.manage.microsoft.com/TermsofUse.aspx"},"mdmAppliesTo":2,"mamAppliesTo":2,"mdmAppliesToGroups":[],"mamAppliesToGroups":[]}'
Invoke-RestMethod –Uri $url –Headers $header –Method PUT -Body $content -ErrorAction Stop

You can do almost anything using the above snippet and changing the endpoint URL and POST contents. Use Fiddler to capture, then replicate in code 🙂

Be warned and use at your own risk, obviously this method is unsupported.

Onedrive For Business Silent Deployment, Configuration and Folder Redirection through Intune MDM for Windows 10

I’ve taken information from several sources and written a single “Do It All – Onedrive For Business configuration script” for the Windows 10 Modern Management (Intune MDM Azure AD Join) scenario.

The script can be deployed through Intune to your Windows 10 MDM clients and will do the following silently:

    • check latest O4B version and update to it
    • detect O4B configuration, start auto config
    • completely silent / invisible configuration with SSO
    • optionally, enable Files On Demand
    • optionally, redirect folders to Onedrive
    • optionally, copy old content

O4BClientAutoConfig + source code.

 

Restarting a x86 Powershell Process as x64 automatically

Let’s say something (like Intune) starts your Powershell script in 32 bit and you really need commands that only 64 bit Powershell has….


#Restart self in x64
If (!([Environment]::Is64BitProcess)){ 
    if([Environment]::Is64BitOperatingSystem){
        Write-Output "Running 32 bit Powershell on 64 bit OS, restarting as 64 bit process..."
        $arguments = "-NoProfile -ExecutionPolicy ByPass -WindowStyle Hidden -File `"" + $myinvocation.mycommand.definition + "`""
        $path = (Join-Path $Env:SystemRoot -ChildPath "\sysnative\WindowsPowerShell\v1.0\powershell.exe")
        Start-Process $path -ArgumentList $arguments -wait
        Write-Output "finished x64 version of PS"
        Exit
    }else{
        Write-Output "Running 32 bit Powershell on 32 bit OS"
    }
}

With the above at the top of your script, it’ll automatically restart itself if needed 🙂

Getting rid of start menu ads in Windows 10 Modern Management using Intune PS script

On a clean install, Windows 10 has ‘suggestions’ in the start menu luring your users into installing stuff like Candy Crush.

If you want to prevent this, put the following PS snippet into a file:


New-ItemProperty -Path "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\ContentDeliveryManager" -Name "SystemPaneSuggestionsEnabled" -Value 0 -PropertyType DWORD -Force | Out-Null
New-ItemProperty -Path "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\ContentDeliveryManager" -Name "SubscribedContent-338388Enabled" -Value 0 -PropertyType DWORD -Force | Out-Null

Then head to the Intune Console, go into device configuration and add the above file:

Make sure you let it run in the user’s context:

And finally, assign it to a group (or groups) containing your users.

If you’re using Windows 10 Enterprise or higher Sku’s, you can also use ADMX backed policies as per RKast’s suggestion in the comments below 🙂

Exchange Online reconnect script v2

A few weeks ago I posted a script that would automatically, periodically, reconnect to Exchange Online. In field testing it would still prompt for credentials after 1-2 days, whatever I did.

So I took a different route and am now rewriting Microsofts’ module on the fly to no longer prompt for credentials. If you use below function to connect to Exchange Online, you should never receive reconnect prompts 🙂

disclaimer: don’t overwrite $o365Creds with invalid creds elsewhere in your script as those are used globally.


function buildResilientExchangeOnlineSession {
    Param(
        [Parameter(Mandatory=$true)]$o365Creds,
        $commandPrefix
    )
    Write-Verbose "Connecting to Exchange Online"
    Set-Variable -Scope Global -Name o365Creds -Value $o365Creds -Force
    $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $o365Creds -Authentication Basic -AllowRedirection
    Import-PSSession $Session -AllowClobber -DisableNameChecking
    Write-Verbose "Connected to Exchange Online, exporting module..."
    $temporaryModulePath = (Join-Path $Env:TEMP -ChildPath "temporaryEXOModule")
    $res = Export-PSSession -Session $Session -CommandName * -OutputModule $temporaryModulePath -AllowClobber -Force
    $temporaryModulePath = Join-Path $temporaryModulePath -ChildPath "temporaryEXOModule.psm1"
    Write-Verbose "Rewriting Exchange Online module, please wait a few minutes..."
    [String]$newContent
    $found = $False
    (Get-Content $temporaryModulePath) | % {
        if(!$found -and $_.IndexOf("host.UI.PromptForCredential(") -ge 0){
            $line = "-Credential `$global:o365Creds ``"
            if($line){
                $found = $True
            }
        }
        if($line){
            $newContent += $line
            $line=$Null
        }else{
            $newContent += $_
        }
        $newContent += "`r`n"
    }
    $newContent | Out-File -FilePath $temporaryModulePath -Force -Confirm:$False -ErrorAction Stop
    $Session | Remove-PSSession -Confirm:$False
    Write-Verbose "Module rewritten, re-importing..."
    if($commandPrefix){
        Import-Module -Name $temporaryModulePath -Prefix $commandPrefix -DisableNameChecking -WarningAction SilentlyContinue -Force
        Write-Verbose "Module imported, you may now use all Exchange Online commands using $commandPrefix as prefix"
    }else{
        Import-Module -Name $temporaryModulePath -DisableNameChecking -WarningAction SilentlyContinue -Force
        Write-Verbose "Module imported, you may now use all Exchange Online commands"
    }
    return $temporaryModulePath
}

CSP delegation on non CSP azure subscriptions

If you’re a Cloud Solution Provider and you supply a CSP azure subscription to that tenant, your AdminAgents will have Owner access to that subscription by default. Lets say the customer also has an existing subscription (maybe a non-profit donation?).

When you add your accounts as Owner to the existing tenant’s (non-csp) subscription, your users are added as Guest accounts in the customer’s Azure AD. This removes the delegated CSP rights on the CSP subscription because the references to foreign accounts break due to the new guest accounts having the same UPN.

So, alternatively, use

Get-AzureRmRoleAssignment -Scope "/subscriptions/<CSP SUBSCRIPTION ID>

on the CSP subscription to get the Foreign Principal ID for your own tenant. Then use

New-AzureRMRoleAssignment -ObjectId <FOREIGN PRINCIPAL ID> -Scope "/subscriptions/ 
<EXISTING SUBSCRIPTION ID>" -RoleDefinitionName Owner

to add the foreign principal ID to the existing customer subscription to get delegated access 🙂
