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 -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

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:

The following script is from this site:

<# .SYNOPSIS Windows Backup Mail Report Written by Joakim, .DESCRIPTION Version 4.1 - Updated 2016-05-31 This script will mail a report from the latest Windows Backup job, can also fetch and generate reports from remote servers.

Microsoft Teams – Welcome Message

Microsoft teams can send welcome messages when a user is added to the teams. This behavior can be altered with powershell

The current setting for the team can be checked with powershell. To run this, you need to be connected to Microsoft 365. For Microsoft 365 management you can install the “Microsoft Exchange Online Powershell Module” from Microsoft 365.

Get-UnifiedGroup -Identity 'Group Name' | fl WelcomeMessageEnabled

The outcome should be True or False. When it is set to True, welcome messages will be send. To change this setting, so welcome messages are not send, change the value to false

set-UnifiedGroup -Identity 'Group Name' -UnifiedGroupWelcomeMessageEnabled:$False

Delete folders with ‘Long Filenames’

When deleting files the following error occurs:

Source Path Too Long
The source file name(s) are larger than is supported by the file system. Try moving to a location which has a shorter path name, or try renaming to shorter name(s) before attempting this operation.

To delete these files use the following robocopy method:

robocopy C:\DELETE-ME C:\{path}\{The Top Level Folder To Delete} /s /mir

After the directory has been removed, remove the remaining folders with:

rd C:\{path}\{The Top Level Folder To Delete}

Backup all SQL databases

The following script can be used to backup all databases from a SQL server. The system databases are excluded. If any other database should be excluded, add them to the “NOT IN” section.

For different date formats in the export, check:

The script is exporting the databases now with the following format: databasename_YYMMDD.bak

DECLARE @name VARCHAR(50) -- database name  
DECLARE @path VARCHAR(256) -- path for backup files  
DECLARE @fileName VARCHAR(256) -- filename for backup  
DECLARE @fileDate VARCHAR(20) -- used for file name
-- specify database backup directory
SET @path = 'C:\Backup\'  
-- specify filename format
SELECT name 
FROM master.sys.databases 
WHERE name NOT IN ('master','model','msdb','tempdb')  -- exclude these databases
AND state = 0 -- database is online
AND is_in_standby = 0 -- database is not read only for log shipping
OPEN db_cursor   
FETCH NEXT FROM db_cursor INTO @name   
   SET @fileName = @path + @name + '_' + @fileDate + '.BAK'  
   BACKUP DATABASE @name TO DISK = @fileName  
   FETCH NEXT FROM db_cursor INTO @name   
CLOSE db_cursor   
DEALLOCATE db_cursor

Administer WID instance with SQL Server Management Studio

Windows Server Update Services (WSUS) can use a Windows Internal Database (WID). This database is manged through WSUS, but occasionally you want to administer this with SQL Server Management Studio.

Install SQL Server Management Studion (Express) on the server where WSUS has been installed. Then connect to the WID database by using the following server name:


Now you can administer the instance.

If you prefer to administer the database from CLI, you can install the SQL Server Command Line Query Utility – SQLCMD.

To connec to to the database instance, run the sqlcmd utility by passing the instance name. If the database is set in single user mode you can change this by running the following commands:

Windows Server 2012R2:
Open Command Prompt with Administrator Rights
sqlcmd -S np:\\.\pipe\MICROSOFT##WID\tsql\query
alter database susdb
set multi_user


Windows Server 2008R2:
sqlcmd -S np:\\.\pipe\MSSQL$MICROSOFT##SSEE\sql\query
alter database susdb
set multi_user

Please Note. It is possible to administer WID instances this way, but it is not recommended. Changes to the WID instance can break the product or changes can be overwritten by updates of the products.
