« Online Conference Burnout | Main | Sandboxing: How to test unfamiliar software securely »

Nov 03, 2021



I have been using Eudora 7.1 for around 20 years and remain very happy with nearly all aspects of it.
The software has not been updated but POP and SMTP remain and so Eudora still works.
Because it has stood still in time with no bloatware and computers have become incredibly faster, Eudora which is a small application works blindingly fast. The program was very mature by version 7.1.

My OS C: SSD drive recently died with no image backup available. So had to start from scratch with everything with a new SSD installed with Windows 10.

Fortunately nearly all my data, including the Data folder for Eudora, had been saved on a separate data drive (as you can direct it to do when you install it). So all of the messages, ini file, mailboxes, address book etc. were saved.

I simply installed Eudora 7.1 (not the 'upgrade' 8.0 beta) in the default Qualcomm folder, and directed it to the pre-existing data folder on the separate hard disk drive during the installation process.

After a reboot, I started the new installation of Eudora and it worked perfectly using all pre-existing options and preferences exactly as I had left it.

With the new SSD drive (the previous drive was six years old) and Windows 10, Eudora was even quicker and worked as well as usual.

Eudora 7.1 lives on!!


If you already have Eudora using a dedicated folder on the Windows 7 machine you can simply copy the folder to the Window 10 and run Eudora.exe. There is no need to actually install the program on the new install. If you then make a shortcut to Eudora.exe on your desktop you are good to go. You don't even have to worry about the registry warning (at least it didn't pop up on my computer).

This is one of the brilliant aspects of older software that does not use the Windows registry: completely portable.


Right now all my attachments are stored on C:\Program Files (x86)\Qualcomm\Eudora\Attach. If I install on a Windows 10 machine and install it on the C drive (a new path), won't archived emails not be able to locate the attachments?

Is there anyone out there who could help me?
I´ve been running Eudora for at least 30 years and still do.
I love it.
But I´ve a problem that I´ve not found a solution to.
I´m Swedish and writing on a Swedish key board.
Quit often, but not always Eudora have problems with our special letters "å" "ä" "ö" in the text flow I write.
I see it perfectly right but the reciting person sees some strange letter combinations for those letters.
Is there any way to fix this?

Ralph Grabowski

As Eudora is an old program, it does not handle modern conveniences like Unicode (displays fonts from many languages) and advanced HTML. This is why you can see strange combinations of letters.

When I try to launch the Eudora installation file on a Win 10 OS I get a message telling me it has been blocked by an administrator. Since I am the administrator of my computer I wonder, what's wrong? What can I do about it?
(The installation file runs fine on a Win XP OS in a virtual machine on the same computer.)

Ralph Grabowski

Windows requires some actions to be performed by the Administrator. This is a form of security, but a very weak form.

You can run Eudora with Administrator rights like this:

1. Right-click Eudora icon, and then choose "Open File Location."
2. Right-click the Eudora.exe file, and then choose "Properties."
3. Click the Shortcut tab, and then click "Advanced".
4. In the Advanced Properties dialog box, turn on the option "Run as administrator".
5. Click OK to close the dialog boxes.

Eudora should run fine now.

Thanks, but it didn't work. (I didn't get the same meny when I right-clicked on the installation file.)

However, I tried another way which worked!
I copied the Eudora program files folder (C:/Internet/Eudora) and the Eudora data files folder (E:/Internet/Eudora) in my Win 7 computer to a C:/Internet/Eudora and a E:\Internet\Eudora folder in my Win 10 computer. Then I copied the content of the launch icon in Win 7 to a new launch icon in Win 10 (which included a pointer to the Eudora data folder).

So far, it works fine! And I don't get any complains from the OS like the one that you get (you wrote above):
"The only catch is that Windows 10 will complain that a registry entry is missing each time you launch Eudora."


I am also a very happy, very long time user of Eudora (1994), and have been using it on Windows 10 without problems, except a minor burp at startup. Launching the application either directly or via shortcut results in a "User Account Control" error appearing asking if I want the application to make changes to my device. Clicking "Yes" results in the programme executing normally. I have tried changing the properties to allow compatibility mode (Win7 and WinXP) and also as administrator, but same startup error appears. Would be nice to see this burp go. Any suggestions?

Yes, Unicode would be nice as I use Chinese a lot. The was a patch for one much earlier version that permitted Chinese, but subsequent updates soon messed that up. Have tried the open source version, but found it wasn't patch on the last 7.1 version. A really good email client!

Ralph Grabowski

My solution to the "User Account Control" error problem is to keep Eudora running all the time.


Eudora is great. The problem is it uses the an old security protocol called TLS 1. And the web host and the email server company I am using no longer supports to you last one and says I need to move to TLS 1.2. So how do I get Eudora to work with TLS 1.2, or conversely does anybody know of a web host/ email server company that still supports TLS V1?

Ralph Grabowski

See my blog https://www.worldcadaccess.com/blog/2020/12/making-eudora-7-work-with-gmail-servers.html on instructions on how to upgrade Eudora to TLS 1.2.


I have missed Eudora! so very much! Glad to see this info & will give it a try! Thank you so much!
Why don't they just make an updated version?

Ralph Grabowski

Qualcomm abandoned Eudora nearly two decades ago, and subsequent attempts (v8.0, OSE, Thunderbird) were incomplete.

I have Eudora installed and its working but mailto link is not working means it is not default program to deal with these links please help if you can. I look for this solution but did not find anywhere yet. When I click some link it does not work and on default mailto link Chrome is specified.

Ralph Grabowski

There is some info at these two sites on dealing with customer MAILTO settings, which I intend to look at, but no promise from me of when!

For Windows 7:

For Windows 10:


Count me as another one who keeps one old machine with Windows 7 and Eudora 7 installed on it. (Lots of history in those emails, I don't want to lose them!)

My question is this: since I already do have all my Eudora stuff in one dedicated Eudora folder, can I simply update my old machine to WIn 10 (or 11?) without disabling my Eudora?

Thanks in advance!

Ralph Grabowski

The bigger question is if your comuter is able to be upgraded to Windows 10 or 11:

Windows 10: probably
Windows 11: probably not, as Microsoft allows it only on recent computers

I have not tried this, as I am so reliant on Eudora that I don't dare upgrade my Windows 7 computer to Windows 10.
