• I found several websites on a Bing search that Edge Chromium had changed the passwords storage method from the way the old Edge did it. My passwords were working in early Sept. They were not working. According to ZD Net, Windows Says and several other sites, Edge Chromium has a big issue remembering passwords!

To develop apps for the new Microsoft Edge, use WebView2, the Chromium-based version of Microsoft’s WebView. If I use a private WSUS server for updates, how can I keep the new Microsoft Edge up to date? After the update is installed, the new Microsoft Edge will check for and install updates automatically via its own updater.

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)

Microsoft Edge Chromium Release Date

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.

For details about the ExtensionInstallForcelist policy, see ExtensionInstallForcelist.
