Outlook is a widely used Microsoft tool and if there is an issue with it, many businesses, individuals, and organizations are massively affected. However, some issues like Outlook missing on Microsoft 365 portal are not across the board; it is only experienced by a few users. Luckily, this guide has all you want to fix the problem and resume your operations normally.

Why is Outlook missing on Microsoft 365?

There are quite a number of reasons that can possibly cause the Outlook icon to miss in Microsoft 365. Unfortunately, we cannot authoritatively narrow it down to one but we can highlight three main ones. The problem can occur if a user is an Outlook business account and has no valid licenses to access the app. Another reason would be if the administrator or another user has removed the Outlook app from the app launcher. Finally, the other reason would be a simple and temporary bug that can be fixed by refreshing your Microsoft 365 portal.

If Outlook is not showing up on Microsoft 365, is missing, or when you pin it on the app launcher it unpins after seconds, try the following solutions to fix the issue successfully;

1. Refresh Microsoft 365 portal or try to access it with another browser
2. Check user licenses
3. Pin Outlook app to the Launcher
4. Reset user permissions using PowerShell

Let us now look at these solutions one by one in detail.

1] Refresh Microsoft 365 portal or try to access it with another browser

Refreshing Microsoft 365 or using another browser to access it fixes any temporary technical hitches the portal might have experienced. The bugs can originate from your browser, network connection, or Microsoft Outlook servers. Whichever the source, you can resolve this by simply reloading the Office portal, restarting your Internet, or using a different browser like Google Chrome or Microfot Edge.

2] Check user licenses

For users in an organization or business enterprise, having the correct license enables you to access Microsoft 365 portal successfully. If the license is missing, revoked, or misconfigured, some apps including Outlook will not show up in Microsoft 365. If you suspect that there is a license issue, contact your administrator to correct the issue from their side.

3] Pin Outlook app to the Launcher

If there are issues with user permissions, then an administrator can use Windows PowerShell to reconfigure them. Follow the steps below if you are the administrator:

• Type PowerShell in the Windows search box and click Run as administrator. Select Yes if you get the UAC prompt.
• To store the user details type the following command line and press Enter on the computer keyboard:

  $Credential = Get-Credential

• The Windows PowerShell credential request wizard will pop up; enter your Microsoft 365 username and password and click OK.
• Now, you need to start a new Microsoft 365 session on PowerShell. To do this, copy and paste the following command line and press Enter on your keyboard:

  $ExchangeSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri “https://outlook.office365.com/powershell-liveid” -Credential $credential -Authentication “Basic” –AllowRedirection

• Next, launch the Exchange Online PowerShell session using the following command and press Enter;

  Import-PSSession $ExchangeSession

• It’s now time to revoke the user permission of the affected user account and cannot access the Shared Mailbox. For this example, we can use [email protected] as the email for the [email protected] user;

  Remove-MailboxPermission -Identity [email protected] -User [email protected] -AccessRights FullAccess

• The final step is to assign the permission again to the user in the Shared Mailbox. Run the following command:

  Add-MailboxPermission -Identity [email protected] -User [email protected] -AccessRights FullAccess -AutoMapping:$false

This should work.

We hope one of the solutions helps you if Outlook is not showing up on Microsoft 365.

Once the add-ins are disabled, close Outlook 2016 and restart the application normally to check whether it now opens as normal or not.

Check for dialog boxes

While performing certain actions on Outlook, it asks for ‘confirmation.’ For instance, if you perform the Dismiss All action on a list of reminders, Outlook displays a message, ‘Are you sure you want to do that.’ You won’t be able to perform that action unless you choose an option on that dialog box.

These dialog boxes often don’t allow Outlook to respond properly, so check for any open dialog boxes on your system. To check the opened dialog boxes, press Alt+Tab, which will allow you to switch from window to window and help you see what dialog boxes are stopping you from responding.

Firewall settings

If Outlook is not opening in Windows 10, it could be because of a dialog box that is being blocked by the security settings. To check for this, go to Control Panel > All Control Panel Items > Security and Maintenance. Under the ‘Security’ heading, click on ‘Allow a program through Windows Firewall.’
