[Fixed] MailEnable Webmail inbox and messages not showing

MailEnable Webmail inbox and messages not showing

Hello Friends,

Recently, I encountered an issue on Windows Server where the MailEnable Webmail was not displaying the inbox and emails properly. Clicking the inbox had no effect. I was able to log in properly but was unable to read email or view emails. This included the inbox, deleted items, sent items, etc.

The server was having Plesk 11.09 installed with Mailenable as the mail server.

It was a server-wide issue and affected all the customer’s accessing email through MailEnable Webmail.

On further investigation, I found that a recent .NET update has broken the webmail in the server such that it will not show folders and messages.

There are many solutions for this. Like, you can upgrade MailEnable to fix this, or you can remove the recent .Net version from your server. However, doing this on a live/production server may lead to breaking down the server configuration, application. So if you want to upgrade MailEnable on your server, a proper and thorough investigation and testing are required to upgrade.

Moreover, if you have an older version of the server/control panel, updating the server/control panel is not a good solution in the production server, without taking all the thorough investigation/testing and preventive measures. So for all those case, there is a workaround for this. The below method will resolve the issue with MailEnable quickly.


1.Connect to the server via RDP

2.Find and Edit C:\Program Files (x86)\Parallels\Plesk\Mail Servers\Mail Enable\bin\Netwebmail\web.config

3.Put the following piece of code somewhere between <system.web> and </system.web>

That’s it.

Adding the above code in web.config will restart application pool for MailEnable in IIS.

Load the webmail Page again. The issue will be fixed and you will be able to view all the folders.

Feel free to comment below in the issue still persists. We will be more than happy to provide the solution at earliest.

Thank you! 🙂
