Win 11 Microsoft 365 Outlook classic cannot open

[ChatGPT]

Julian — your photos actually show that WebView2 is installed on your PC.

Why you “can’t see it” as “WebView2 Runtime”​

On many Windows 11 / Microsoft 365 systems, WebView2 is installed as a system component and may not appear clearly in “Installed apps” or “Programs and Features” with the exact name “Microsoft Edge WebView2 Runtime”. But it is still present on disk, and the installer correctly detected it.

---

Where WebView2 is (your screenshot proves it)​

You are in:
C:\Program Files (x86)\Microsoft\EdgeWebView\
Inside it you have:
Application\
and inside that you have version folders like:

• 145.0.3800.70
• 145.0.3800.82

That is exactly how WebView2 Runtime is stored.

To verify 100%​

1. Open this folder:
   C:\Program Files (x86)\Microsoft\EdgeWebView\Application\145.0.3800.82\ (or the newest number)
2. Look for:
   msedgewebview2.exe

If you see msedgewebview2.exe, then WebView2 Runtime is definitely installed.

---

Why your installer said “already installed”​

Because Windows detected the installed WebView2 runtime in that EdgeWebView folder, so it refused to install a second copy. That’s normal and good.

---

Next step (if your goal is still adding giulianogini@outlook.com to Outlook Classic)​

Since WebView2 is present, the “Something went wrong” when adding Outlook.com is usually caused by Microsoft sign-in tokens/caches (WAM/Office identity), not by WebView2 missing.
If you want, tell me: when you try to add [email]giulianogini@outlook.com[/email] now, does it:

• fail immediately with “Something went wrong”, or
• does it open the Microsoft sign-in page and then fail?

Reply with which one you get, and I’ll give you the exact fix steps for that case.

sorry but i still don't see any msedgewebview2.exe there is only numbers?

You’re looking in the right general area, but what you’re describing (“I only see numbers”) usually means you’re one level too high in the folder tree.
Those “numbers” are the version folders. The file msedgewebview2.exe is inside one of those version folders.

1) Go into the newest version folder​

1. Open File Explorer and go to:
   C:\Program Files (x86)\Microsoft\EdgeWebView\Application\
2. Double‑click the folder with the highest number (for example 145.0.3800.82)
3. Inside that folder you should see many files and folders, including msedgewebview2 (Windows may hide “.exe”, so it may appear as just msedgewebview2).

If you still only see more number folders, then you’re not inside the version folder yet.

---

2) If it’s still not there, check the other common install location​

Sometimes it’s installed here instead:

• C:\Program Files\Microsoft\EdgeWebView\Application\ (note: not “(x86)”)

Repeat the same: open the newest version folder and look for msedgewebview2.

---

3) Easiest proof: search the whole PC for the file​

1. Open File Explorer
2. Click This PC
3. In the search box (top right) type:
   msedgewebview2.exe
4. Wait for results

If it exists anywhere, Windows will find it.

---

4) Quick command method (even easier)​

1. Right‑click Start → Terminal (Admin) (or Command Prompt)
2. Run:
   where /r "C:\Program Files (x86)" msedgewebview2.exe
   If nothing found, run:
   where /r "C:\Program Files" msedgewebview2.exe

---

Please do this and tell me the result​

When you open C:\Program Files (x86)\Microsoft\EdgeWebView\Application\145.0.3800.82\ (or whatever your newest folder is), what files do you see? If you can, post one photo of inside the version folder (not the folder that contains the version numbers).

Yes I now understood and I see it clearly whereby before I wasn't actually clicking expanding the file numbers! however after thought I decided not to include the giulianogini@outlook.com in outlook classic instead if I need it I will use directly the website of outlook.
I was only worried about why I couldn't add it to outlook classic but now it doesn't matter anymore, but if I should have the same problem error while using another website in the future of the same nature I will contact you again.
quite simply I wanted to also remove this error.
Thank you

That makes perfect sense, and your screenshot confirms everything is OK:

• You are inside the newest WebView2 version folder
  C:\Program Files (x86)\Microsoft\EdgeWebView\Application\145.0.3800.82
• And you can clearly see msedgewebview2.exe there.

So WebView2 Runtime is installed correctly. The reason Outlook Classic couldn’t add [email]giulianogini@outlook.com[/email] earlier was not “missing WebView2”, but more likely Microsoft sign-in/token issues (WAM/credentials/proxy/time), which can happen occasionally on Windows 11.
Using Outlook.com in the browser is a perfectly good solution if you don’t need that account inside Outlook Classic.
If you want to remove/avoid similar sign-in “account needs attention” messages in Windows (Widgets/Discover), the simplest approach is:

• Settings → Personalization → Taskbar → Widgets = Off (optional)

Any time you see an error again, just post the exact code/message like you did (that helps a lot), and we’ll sort it quickly.
