Plesk for Windows Webmail Error: Webmail Cannot be Found


If you are getting an error that says “File cannot be found” or if you are receiving a 404 error when you try to go to, this is due to the fact that default mapping application extensions do not include php support.To solve this, do the following:

1. Go to “Start” – > “Administrative Tools” -> “Internet Information Services (IIS) Manager”
2. Expand the server (local computer)
3. Expand “Web Sites”
4. Right-click on “webmail(default)” and click “Properties”
5. Go to the “Home Directory” tab
6. Click on the “Configuration” button towards the bottom.
7. In the list box that appears, if the extensions php, php3, and phtml do not exist, you have found your problem.
8. Click “Add”
9. Type the location of the file php.exe in the “Executable” field. For example: C:\Program Files\SWsoft\Plesk\Php\php.exe
10. Type: .php in the “extension” field.
11. Leave everything else as default checked. Click “OK”.
12. Repeat this setup using the same executable and adding the extensions: .php3 and .phtml
13. Exit out of everything. Webmail should be up and running now.

  1. When i try to access to webmail of mine domains i receive this type of error: HTTP Error 401.1 – Unauthorized: Access is denied due to invalid credentials.

    I found this help using google… and in fact in my case in the list box i have nothing so i have to add php.exe as the document before said but when i try to add it, it says: “entries containing spaces need quotes around the file/path portion”
    So i can’t insert it because this string is wrong C:\Program Files\SWsoft\Plesk\Additional\Php\php.exe
    What it wants i do? i don’t understand….
    And the problems for the unworking webmail is really this?

  2. Is this problem exists only while accessing webmail?

    Check these urls, it may help you 😉

  3. do you have msn, can i talk with you?

  4. I tried to se the same domain to another server but linux with the same plesk version and i still have that error

  5. hi mohammed

    while search for the plesk windows webmail issues – i came across your blog and found this post.

    i have everything setup in line with the normal setup one can have on plesk 8.3 windows – although the gives me the 404 not found error.

    when i access the webmail it actually gives me the url in below format with iis 404 not found error.

    I have done alot of troubleshooting but nothing is working out

    any idea??

  6. I am having the same problem and I have done everything you had, without success.
    I am with version 8.4 of plesk what else needed to make the horde work.
