This account is not supported in Outlook

If you are trying to add a Microsoft 365 Work or School account to the new Outlook and receive this message in Windows:

This account is not supported in Outlook for Windows due to the license provided by your work or school. Try to login with another account or go to Outlook on the web.

Or this message in new Outlook for Mac:

This account cannot be added. The license provided by your work or school does not enable access to Outlook for Mac. Please access your email through Outlook on the web instead.

Those messages tell you that you must have a software subscription for the mailbox to use it in the new Outlook.

Microsoft is currently requiring a Microsoft 365 desktop software license to use the new Outlook apps with a Microsoft 365 Work or School account and the account that you are trying to add does not include a software subscription. This includes Business Basic, Exchange Online Plan 1, mailboxes from GoDaddy or other resellers, and shared mailboxes within your own tenant.

Users with shared mailboxes will be able to open them in new Outlook as a shared mailbox.

In new Outlook on Windows, the shared mailbox is added at the bottom of your account's folder list. You'll need to select the From address from the menu to send using that address.

To add the account as shared on new Outlook for Windows, right-click on your email address in the folder list and choose Added shared folder or mailbox. Start typing the account name or email address and select it when it comes up.

In Outlook for Mac, the shared mailboxes will be in the folder list as if it's another account. New messages and replies created within the mailbox will use the shared mailbox address.

In Tools > Accounts, select your account then click the Delegation and Sharing button. Select the Share with me tab, then the + at the lower left and start typing the shared mailbox name. Select the account when it comes up.

Events from Email

Every few weeks someone has a questions about the Events from email feature in Outlook on the web.

“I changed the Events from email setting to "Don't show event summaries in email or on my calendar." But I’m still getting events added to my calendar. "

If events are showing up on the calendar, it is most likely due to meeting invitation spam, not Events from email. The Exchange server automatically processes meeting invitations and adds them to the calendar as tentative so it’s on your calendar, waiting for you to accept or decline.  Unfortunately, you cannot prevent Outlook from adding meeting invitations to your calendar automatically. You’ll need to delete them from the calendar.

The Events from email option is used with specially crafted messages for package deliveries, and rental cars, hotel, and airline flight reservations sent to Outlook.com or Microsoft 365 mailboxes.

These messages have a summary card at the top with the reservation or package information and a link for “Outlook found new events" under the subject and address block area and “View in calendar” in the summary card. The summary card displays in all versions of Outlook, but the settings are only in Outlook on the web (and now new Outlook).  Some of the summary cards can be huge, but you can hide the summary card by clicking the ʌ icon on the right side of the message.

To check or change the Events from email settings, open View tab > View settings > Calendar > Events from email.

Your choices for packages and reservations are:

  • Show event summaries in email and on my calendar
  • Only show event summaries in email
  • Don't show event summaries in email or on my calendar

I have screenshot of the Events from email summary cards here:

Logging into multiple Outlook on the web accounts

If you have more than one Microsoft account, you’ve faced the problem of either signing in and out to switch accounts or using “Sign in with a different account” to switch accounts and discovering you were switched back to the original account.

The solution: browser profiles. All major browsers support separate profiles, and they are easy to set up and switch between in Edge and Chrome.

While you can use private browser windows, you’ll be able to stay signed in to your account when you use browser profiles.

When you use separate profiles, cookies, passwords, history and other properties cached in the browser are kept separate. The advantage over using a different browser: you can open another profile from the browser window.

To create a profile in Edge or Chrome:

Click on your avatar in the address bar area, in Chrome and some versions of Edge, it’s on the right, but may be on the left.

Click the avatar to expand the menu and at the bottom of the menu, click Add (Chrome) or Set up new personal profile (Edge).

Name your profile. You can sign into the account you’ll be using with the profile, to sync history and passwords. Or use it without signing in.

When you want to use the profile, click on the avatar and select the profile name from the menu. This will open a new browser for your profile.

If you want to pin a shortcut for the profile to your taskbar, create a shortcut for Edge, using this command as the target (with the correct profile name).
"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --profile-directory="Profile 2"

To create profile shortcuts in Chrome, open Settings > You and Google > Customize profile. Under the Pick an avatar section is a switch to create a desktop shortcut for the profile.

Edge has an option that will open the profile an email account is signed into (for syncing) when you open links in that email account. You can also configure Edge so specific links always open in a specific profile. I find it annoying, but it might be useful if you use work and personal Microsoft accounts and want to keep everything to separate.
