Microsoft Edge 365

You'll use your Microsoft account for everything you do with Microsoft 365 or Office. If you use a Microsoft service like Outlook.com, OneDrive, Xbox Live, or Skype, you already have an account. If you're an Edge user and have Microsoft 365 for business (for work or school), you have a new perk—a default home page and new tab pages especially for you. The 'Microsoft 365' tab gives you easy access to your most-recently-used Office cloud files (both SharePoint and OneDrive), your SharePoint sites, and the top Office Online apps.

As an admin for Exchange Online, you can set up Outlook on the web (formerly known as Outlook Web App) to allow sending and receiving S/MIME-protected messages. Use the Get-SmimeConfig and Set-SmimeConfig cmdlets to view and manage this feature in Exchange Online PowerShell. To connect to Exchange Online PowerShell, see Connect to Exchange Online PowerShell.

For detailed syntax and parameter information, see Get-SmimeConfig and Set-SmimeConfig.

Considerations for new Microsoft Edge (Chromium-based)

To use S/MIME in Outlook on the web in the new Microsoft Edge web browser, you (or another admin) must set and configure the Microsoft Edge browser policy named ExtensionInstallForcelist to install the Microsoft S/MIME extension in the new Microsoft Edge. The policy value is maafgiompdekodanheihhgilkjchcakm;https://outlook.office.com/owa/SmimeCrxUpdate.ashx. And note that applying this policy requires domain-joined or Azure AD-joined devices, so using S/MIME in the new Microsoft Edge browser effectively requires domain-joined or Azure AD-joined devices.

For details about the ExtensionInstallForcelist policy, see ExtensionInstallForcelist.

This step is a prerequisite for using new Microsoft Edge; it does not replace the S/MIME control that's installed by users. Users are prompted to download and install the S/MIME control in Outlook on the web during their first use of S/MIME. Or, users can proactively go to S/MIME in their Outlook on the web settings to get the download link for the control.

Considerations for Chrome

To use S/MIME in Outlook on the web in the Google Chrome web browser, you (or another admin) must set and configure the Chromium policy named ExtensionInstallForcelist to install the Microsoft S/MIME extension in Chrome. The policy value is maafgiompdekodanheihhgilkjchcakm;https://outlook.office.com/owa/SmimeCrxUpdate.ashx. And note that applying this policy requires domain-joined computers, so using S/MIME in Chrome effectively requires domain-joined computers.
