There are situations where you would like to enforce an update of the Exchange Global Address list (GAL) in Office 365. With a few steps this can easily be done!
STEP 1: First we will need to make sure that our admin account has the correct permissions. Go to the Exchange Online Admin center, and then to permissions – admin roles and click on the + sign to add a new role
We will now create a new role group. Give it the name Address List Management and assign the role Address lists, and make sure to add the administrator account as a member. Click Save when ready.
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?
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.
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
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.
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:
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.
We will need to fill multiple Active Directory user attributes to resolve this issue.
You want to move your mailboxes from Exchange on-premise to Office 365, and you want to give you users a smooth transition experience, then you will definitely need to implement the following to automatically create and configure a new Outlook profile on all Windows devices.
Within Outlook Microsoft has created ZeroConfigExchange to setup new profiles with minimal user interaction. Depending on your exact configuration Outlook will be configured fully automatically, or the user is required to fill in his email address and/or password.
Microsoft released Lighthouse last weekend, and since this is a great feature, I wanted to implement it as soon as possible, but the Microsoft docs might be a bit confusing, so I wanted to simplify the manual, so here it is! We will be using PowerShell, as this makes life so much easier, and faster.
Your admin tenant needs to have a valid Azure subscription
You need to have a native user account with the new Owner role in the tenant that you want to manage (Customer tenant)
Azure PowerShell module: AZ (Install-Module -Name az)
