Microsoft 365 – Self-service purchase

Self-service purchase gives users a chance to try out new technologies and develop solutions that ultimately benefit their larger organizations. Central procurement and IT teams have visibility to all users who buy and deploy self-service purchase solutions through the Microsoft 365 admin center. Admins can turn off self-service purchasing on a per product basis via PowerShell..

To read more about the Self-service purchase option, go to: Self-service purchase FAQ | Microsoft Docs

To disable the AllowSelfServicePurchase do the following:

#Install module
Install-Module -Name MSCommerce

#Import module
Import-Module -Name MSCommerce

#Connect
Connect-MSCommerce

#Get details
Get-MSCommerceProductPolicies -PolicyId AllowSelfServicePurchase

#Disable ProductID (or $True to enable)
Update-MSCommerceProductPolicy -PolicyId AllowSelfServicePurchase -ProductId CFQ7TTC0KP0N -Enabled $False

The following table shows the ProductID needed to enable or disable

Cannot Tenant to Teams Only upgrade mode in Teams Admin Center

When changing the coexistence mode to Teams only you get the following error: Please see the unsaved sections higlighted in red below:

We cannot see what the problem is when switching to teams only. With powershell it has better error messages. Use the following powershell to connect to teams and change the tennant

#Connect with the SkypeOnlineConnector
Import-Module SkypeOnlineConnector
$sfbSession = New-CsOnlineSession
Import-PSSession $sfbSession

#Change the tennant to TeamsOnly
Grant-CsTeamsUpgradePolicy -PolicyName UpgradeToTeams -Global

The following message appears:

This organization cannot be upgraded to TeamsOnly at the tenant level because there is an on-premise deployment of Skyp
e for Business detected in 1 or more of it sip domains

To change this use the following command:

Disable-CsOnlineSipDomain -Domain domainname

After all domains have been altered, you can change the tenant to TeamsOnly with Powershell or the GUI:

Office 365 Hide mailboxes from the GAL

Export all mailboxes who are shown in the GAL

Get-Mailbox -ResultSize Unlimited | Where {$_.HiddenFromAddressListsEnabled -eq $false}| select UserPrincipalname, HiddenFromAddressListsEnabled | Export-Csv "c:\temp\gal.csv" -NoTypeInformation -Encoding UTF8

Show all private groups which are shown in the GAL (Teams groups are default hidden)

Get-UnifiedGroup | Where-Object {$_.AccessType -eq 'Private'} | select Displayname, PrimarySMTPAddress

To hide a single mailbox use the following command:

Set-Mailbox -Identity [email protected] -HiddenFromAddressListsEnabled $true

To hide multiple mailboxes from the GAL, create a CSV file and use that as input to hide the mailboxes:

Import-Csv 'C:\Hide_Mailboxes.csv' | ForEach-Object {
$upn = $_."UserPrincipalName"
Set-Mailbox -Identity $upn -HiddenFromAddressListsEnabled $true
}

To hide a single group use the following command:

Set-UnifiedGroup <group> -HiddenFromAddressListsEnabled $true

Or hide all private groups at once:

Get-UnifiedGroup | Where-Object {$_.AccessType -eq 'Private'} | Set-UnifiedGroup -HiddenFromAddressListsEnabled $true

Veeam: Your License consumption has been exceeding the license cap

When using Veeam backup for Microsoft Office 365 it is possible you get a license error during backup. This is because when you move a Microsoft 365 license to a new user, this needs a backup to and counts as a second Veeam license.

Normally this should not be a problem, you can use more Veeam licenses than you have (10% of extra licenses or 10 user accounts -whichever is greater-) to overcome this issue. And if a user does not have a restore point in the past 31 days the license will be available again. To see the more information about licenses check this page out: Licensing and License Types – Veeam Backup for Microsoft Office 365 Guide

If Veeam is not backing up anymore because you do not have enough license, you should purchase new ones or free some.

To revoke licenses without waiting you can use powershell. To revoke licenses you need to remove all of the user’s data from all the repositories prior to revoking the license.

Use the following procedure to remove user licenses: Remove User License in Veeam Backup for Microsoft Office 365

Use the following powershell command to check which data a user has on a repository:

$repository = Get-VBORepository -Name "REPOSITORY" 
$user = Get-VBOEntityData -Type User -Repository $repository -Name "[email protected]" 
$user

Email

If the user has email existing on the repository, you will use the following section:

#This remove script is used for repositories containing users Email
#Fill in "REPOSITORY" with the name of the repository as it is showing in Veeam Backup for Office 365 and the email address of the user you wish to remove the data for "[email protected]"

$repository = Get-VBORepository -Name "REPOSITORY" 
$user = Get-VBOEntityData -Type User -Repository $repository -Name "[email protected]" 
Remove-VBOEntityData -Repository $repository -User $user -Mailbox -ArchiveMailbox -OneDrive -Sites
#Y will accept the deleting of data

Remove License

Once you have removed the user’s data from all configured repositories, then you can remove the license for this user. The below script will pull the organization you have added into the console and desired user to then release the license. If you missed a repository, the error will tell you on what repository you still have remaining data:

#If there is no more data for this user on any repository you can use the following to remove the license
#Fill in the domain name as it is shown in Veeam Office 365 "DOMAIN.onmicrosoft.com" and the users email address "[email protected]"

$org = Get-VBOOrganization -Name "DOMAIN.onmicrosoft.com"
$licensedUser = Get-VBOLicensedUser -Organization $org -Name "[email protected]"
Remove-VBOLicensedUser -User $licensedUser

No Email

If a user has no email data look at the following article to delete sharepoint or onedrive data: Remove User License in Veeam Backup for Microsoft Office 365

Failed To Disable The Mailbox Due To a Conflict In Directory Settings

If you have a conflict in directory settings between Microsoft 365 and your on premise location use the next procedure to solve this

Check if the affected mailbox in Exchange Online is an usermailbox

get-recipient user | fl recipient*

If not already, disable the user account in the on-premise environment.

disable-mailbox user

Wait (or force) until the changes replicate to Microsoft 365. Once it is synced, enable the on-premise object as an remote user mailbox

Enable-RemoteMailbox user -RemoteRoutingAddress [email protected]

Wait (or force) until the sync to Microsoft 365 has been completed and then check the user. The error message should be gone and a license can be added

Windows Backup Mail Report Script

Earlier i wrote a script to check for windows server backup results. At the next site a better script is written to report the results of windows server backup:

Configure Email notification for Windows Server Backup

When you need to rely on Windows Server Backup, you want some sort of reporting. A lot of scripts with mailing functions are available (e.g. WSB Backup to network with email notification and rotation) . If you want to rely on simple messaging from the server itself, you can use scheduled tasks for this.

Windows Server Backup writes events to its own event log (event logs > Applications and Services Logs > Microsoft > Windows > Backup > Operational). We can use these successful (4) and unsuccessful (5) events as a trigger.

Create two scheduled tasks (can run under system) with the following triggers:

Trigger for a successful event

Trigger for an unsuccessful event

In the action of the tasks, run a powershell command to send a mail.
