Office 365 Set language and time zone for all users with PowerShell (Manual)

When you create a new Office 365 tenant, all user mailboxes will have the default timezone and language. In my case, I work in the Netherlands, the preference for most companies is to set the Time zone to Central European Time (GMT +1) and the language of the users default folders to Dutch.

You can either ask the users to logon to webmail using https://outlook.office.com and fill in the first time question to set the time zone and default language. But how cool would it be to do this for all your users using PowerShell?

Azure Risk based conditional access explained and how to set it up!

With the Azure AD Premium P2 license you are entitled for Azure AD Identity Protection. You will get the option in Conditional Access to assign risk level based options to your policies. Azure AD Identity Protection can detect six different types of suspicious sign-in activities with 3 different levels of risks.

Six suspicious sign-in activities and 3 risk levels

With the riks levels combined with conditional access policies we can protect sensitive application and data access. With this article I am going to show you how to create risk-based conditional access policies

So let’s create a Policy and get Conditional Access applied with risk levels

Step 1: Log in to the Azure Portal: https://portal.azure.com

PowerShell script to export and import legacy Exchange x500 addresses (Manual)

When you’re migrating from one Exchange environment to another, or from on-premise to Exchange online without using the hybrid setup, the most forgotten part is the migration of the users x500 address. The reason why this is so important is because Exchange uses this to deliver local emails instead of the SMTP address that is normally associated with email. (This also goes along for calendar appointments)

So, by not migrating the x500 address it means that communications will fail when changing calendar appointments, or replying on old emails. To prevent this we will need to export the ExchangeLegacyDN from Active Directory, and import it again as a ProxyAddress in Active Directory.

Export the x500 address (ExchangeLegacyDN)

Step 1: From your source Active Directory, look up the distinguishedName, and copy the content of the value.

Enforce (Azure) MFA with Conditional Access policies

Multi Factor Authentication (MFA) is an added security feature from Azure which I believe that should be enabled by default for everybody in Office 365 and Azure. There for this manual how to enforce (Azure) MFA for all users using Azure Multi Factor Authentication

MFA can prevent unauthorized access in case of the following events:

  • Leaked credentials
  • Sign-ins from anonymous IP addresses
  • Impossible travel to atypical locations
  • Sign-ins from unfamiliar locations
  • Sign-ins from infected devices
  • Sign-ins from IP addresses with suspicious activities

Using Conditional access we can ensure that your users and company data is safe. Important to know is that Office 365 MFA is free of charge, and if you have Azure AD applications an Azure AD Premium license is required.

Named location

If you want to mark your locations as trusted location, you can do that if you have a static public IP. So the first steps are there to define your office locations.

Exchange Online: Set default calendar sharing permissions for all users

In a new Exchange (Online) environment you might want to change the default calendar sharing permissions for all users. By default the sharing permissions for the entire organization are set to “Can view when I’m busy”.

Some companies have a different wish on the default calendar settings of their users. The preferred setting might be “Limited details”. This will show just the headlines and location of the calendar.

If you try to open an invite, it will notify that you do not have access.

So, what options do we have? From the Outlook app you can see that there are 5 options to choose from. (See screenshot below)

Change default send items behavior of Auto-mapped Shared Mailboxes

A commonly heart end-user frustration with Auto-mapped shared mailboxes is that Send emails from the shared mailbox end up in the send items of the user it self. In the past you would need to set a registry key on the client computer to get this resolved. But with Office 365, there is an easy way to change this behavior for every user.

PowerShell

With PowerShell this job is done in less than a minute in just 2 simple steps.

STEP 1: First connect to Exchange Online using the following commands:

$UserCredential = Get-Credential

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection

Import-PSSession $Session 

STEP 2: Now run the following command to set the default behavior for all Shared Mailboxes in your Exchange Online environment.

Get-Mailbox | Where {$_.RecipientTypeDetails -eq “SharedMailbox”} | Foreach-Object {Set-Mailbox -identity $_.Alias -MessageCopyForSentAsEnabled $True } 

Azure SQL update statistics (Manual)

I recently run into a case where I needed to update statistics of an Azure SQL Database because of poor performance and deadlocks. Preventing disruptions is key, so it is important to do something about it. With a simple script we can update the statistics easaly.

Why should I update statistics?

SQL Server statistics are essential for the query optimizer to prepare an optimized and cost-effective execution plan. These statistics provide distribution of column values to the query optimizer, and it helps SQL Server to estimate the number of rows. The query optimizer should be updated regularly. Improper statistics might mislead query optimizer to choose costly operators such as index scan over index seek and it might cause high CPU, memory and IO issues in SQL Server. We might also face blocking, deadlocks that eventually causes trouble to the underlying queries, resources.

The script

Just execute the following query on your database and you should be good to go! Keep in mind, depending on your database this might take a while. During this script your database will get slow, but will remain online.

SET NOCOUNT ON
 GO

 DECLARE updatestats CURSOR FOR
 SELECT table_schema, table_name  
 FROM information_schema.tables
        where TABLE_TYPE = 'BASE TABLE'
 OPEN updatestats

 DECLARE @tableSchema NVARCHAR(128)
 DECLARE @tableName NVARCHAR(128)
 DECLARE @Statement NVARCHAR(300)

 FETCH NEXT FROM updatestats INTO @tableSchema, @tableName

 WHILE (@@FETCH_STATUS = 0)
 BEGIN
    SET @Statement = 'UPDATE STATISTICS '  + '[' + @tableSchema + ']' + '.' + '[' + @tableName + ']' + '  WITH FULLSCAN'
    EXEC sp_executesql @Statement 
    FETCH NEXT FROM updatestats INTO @tableSchema, @tableName
 END

 CLOSE updatestats
 DEALLOCATE updatestats
 GO
 SET NOCOUNT OFF
 GO

How to solve Failed to sync the ArchiveGuid in Office 365 (Manual)

Last few weeks I’ve been struggling with an very difficult Office 365 / Exchange Online case, that got escalated to multiple Microsoft departments to be fixed. I already found one part of the solution, but Microsoft found the second part. Today I would like to take you through all the steps to fix possible causes and resolutions. So the initial problem started with the following error in the Office 365 admin portal with the affected users:

Failed to sync the ArchiveGuid 00000000-0000-0000-0000-000000000000 of mailbox MailboxGuid because one cloud archive CloudArchiveGuid exists.

Another symptom is the mailbox provisioning gets stuck, and hangs on “We are preparing a mailbox for this user”

You will only see this error with AD connect sync enabled environments. The problem occurs when the on-premise value mismatches with the Online Archive Guid. With just a few easy steps we can fix this issue.

Resolution

We will need to fill multiple Active Directory user attributes to resolve this issue.

Deploy Azure Application Gateway with http to https redirect

Azure Application Gateway is an advance type of load-balancer. Where an Azure Load-balancer routes traffic on the transport layer (OSI Layer 4 | TCP + UDP) the Application Gateway is a way more advanced load-balancer. It can route based on URL as well on path’s. On top of that it can do much more, like SSL offloading, autoscaling, redirection, multiple site hosting and the most import of all, it can include a web application firewall (WAF)

Afbeeldingsresultaat voor azure application gateway

With all the features that the Azure application gateway provides, we should be able to setup multiple websites listening on different ports and url’s behind one Azure Application Gateway with just one external IP address.

With this guide you should be able to setup an application gateway with multiple site hostname match and http to https redirect. In this manual we will be using Atlassian Jira and Confluence as an example.

So what are we going to setup:

  • Deploy Azure application gateway
  • Configure 2 external URL’s (jira.2azure.nl and confluence.2azure.nl)
  • We will redirect port 80 to 443 for both websites
  • Jira will be listening on port 8080 internally (Default port)
  • Confluence will be listening on port 8090 internally (Default port)

For this guide the VNET, subnets and the virtual machine hosting both websites have already been deployed. During this guide we will not deploy a Web Application Firewall, I will tell more about that in upcoming blog article.

The setup in an overview.
