If you only use your personal mailbox, you don't have to change anything in the Outlook e-mail program on your managed work laptop/PC of the university, if you only use your personal mailbox. If you use one or more shared mailboxes, you need to take action (see 'I use a shared mailbox' below).

Use MS Outlook app.

You can continue to use the Apple Mail app, but then you will not be able to use shared mailboxes or archived mailboxes.

The steps are:

1. Delete the existing university account.
2. Go to Applications and open the MS Outlook app.
3. Click Preferences from the Outlook menu and click Accounts.
   Click on the + at the bottom left to create a new account.
4. Enter your full e-mail address at the university. Click Continue.
5. When the login window appears, your university e-mail address is entered under the username. Replace the email address at username with your university Microsoft username: <ULCNusername>@vuw.leidenuniv.nl.
   This is an important step to pay close attention to. Enter your usual ULCN password. Click Sign In.
6. You will receive a message that you want to approve this connection in MS Authenticator. Click Approve.
7. Outlook is now set up. The Autodiscover screen may appear. Check 'Always use my response for this server' and click Allow.

Go to the Office portal. Do not continue to use the old webmail address (webmail.campus.leidenuniv.nl). Log in with your university Microsoft account: <ULCNusername>@vuw.leidenuniv.nl and your usual ULCN password.

In the Office portal you will find your frequently used apps on the left of the screen, including the Outlook app. It is therefore possible that the Outlook app is still at the bottom in All apps.

Write down the name of this mailbox beforehand so that you can link it yourself.

Steps to add a shared mailbox to your personal mailbox:

1.  Select the File tab and choose + Add account.
2. Enter the e-mail address of the shared mailbox, leave any other fields blank and click Next step.
3. When a message appears, choose Office365 in the Advanced installation window.
4. Click More options > Use other account and fill in your usual ULCN username with 'vuw\' in front of it. Example: username 'jansenj' becomes 'vuw\jansenj'.
5. Close Outlook and restart it for the changes to take effect.

During the day prior to the mail migration, the link between your mailbox and a shared mailbox (if you use one) may be gone for a while. That is temporary. Restart Outlook later in the day to fix this.

Log in with MFA authentication for the mailbox, just like with the other Office 365 products. See instruction movie and explanation in the helpdesk portal.
