- Microsoft Edge Version 143.0.3650.96 (Official build) (64-bit) And NOT working. ----------- Edited: After a Remove/ Add works again. Maybe the updates are not auto-collected...
- Sadie
- Like the others, this did not work. I'm on Windows 11.

- Fails to work with EDGE on MacOS26, even with extensive troubleshooting and reporting issues to enterprise business help desk.
- Josh
- Giving this three stars because it is a pain to setup. Anyone having issues, you have to go to the extension options and manually add your domain for what web outlook you have. Mine was outlook.office.com so I added that and then restart. It will work after that.
- Ryan
- Doesn't work, if a second component is required it sure would be nice to know what that might be.
- Claudio
- funktioniert bestens. ich musste jedoch, nachdem ich das Add-On installiert hatte, in Outlook (Web) nochmals auf die Fehlermeldung klicken. anschliessend Fenster aktualisiert und alles funktionierte.
- Votaw,
- I couldn't get it to work either...wasted my time.
- Lukutin,
- Amazing! Love it! Doesn't work.
- Daniel
- Webmail still refuses to encrypt or sign, but prompts with a red banner including a button that says "Install S/MIME" but does not actually do anything. You might think a Microsoft extension for a Microsoft browser would work with a Microsoft website, but alas, you'd be a fool for doing so, as I was.
- Sarah
- Does not work!
- James
- The app most definitely works for verifying digital signatures on emails. It requires installing a second component as well. I would suggest opening a support ticket if you have trouble.
- Danielle
- DOES NOT WORK!!!!!! I installed this and I still get the same message.
- Brian
- It doesn't work. MS Edge still asks you to install something extra, and none of it works.
- Petr
- Vůbec nefunguje. V Outlooku se to tváří, že stále není nainstalované.
- Robert
- No way to install on an air gapped network

- does not work

- Outlook website says you need to install this to use S/MIME. After installing this it still says you need to install it.
- Christie
- Doesn't work for the entire Marine Corps for every scenario (i.e., on prem and USMC imaged/personal machines remotely). That's over 170K users! Why even have a web version of Outlook if you can't sign or encrypt/decrypt an email? It obvious from the ridiculous amount of negative user reviews over several years that Microsoft couldn't care less about this security issue.

- This extension does not work.
- Stemy
- This extension (and the Outlook desktop app) works great when properly configured with an infrastructure that supports S/MIME signing and encryption. Users reporting that the extension does not work have not configured it correctly. Currently supporting it just fine for about 700k users.
- Salama,
- This stupid extension breaks things rather than fixes them, would've uninstalled if I could
- Todd
- Works great for me. No issues
- JOSEPH
- Works completely fine for me in Edge browser. I am using the last version: 20.20.514.1 (May 19, 2020). Have you set the S/MIME options? Check: Microsoft websites, Other work or school domains. Then add the domain to the list you trust: For example: webmail.apps.com
