These are notes to remind myself how to deal with this clumsy but useful (nevertheless!) software. Eudora is VERY unfriendly (but I keep it because of mailboxes are discrete units which I can read like text files if I ever need to – not that I know of any such need so far).

Installing a fresh version of Eudora

Either get it from here http://www.eudora.com/download/

or from: https://wiki.mozilla.org/Eudora_Releases

Backing up Eudora data files

While the software gets installed in C:\Documents and Settings\All Users\Documents\Eudora7
it stores the actual data in: C:\Documents and Settings\personal\Application Data\Thunderbird

So backup the Thunderbird data periodically. Software can always be re-installed.

How to restore Eudora when a fresh hard disk is installed

Copy the Thunderbird file back to: C:\Documents and Settings\personal\Application Data\Thunderbird

(each time a new hard disk is installed, and you install eudora afresh, it will automatically create a thunderbird directory but that will have limited data. Just overwrite it with the backup and things will get back to normal again)

Using Eudora with Gmail

Make sure you LEAVE MESSAGES ON SERVER!!!!

Also, you can't download email without first switching off the safety features. You can temporarily disable, then download, then switch off.

Managing Eudora 7.1 with multiple users

How does one make Eudora work with 'limited users' on Windows XP?
Problem: Error message "Could not rename file …descmap.tmp to …eudora\descmap.pce" – but you could get a zillion types of strange messages if sharing is not done properly.

Solution that seems to be working for me:
1. Log on as Administrator.
2. Drop the entire Eudora folder into C:\Documents and Settings\All Users\Shared Documents
3. I don't know how I got it done, but the first step is to ensure that the Sharing and Securing option (right click on a folder) lead to an option to share or not share the folder. That is not a natural phenomenon. Something has to be done to make it work.
4. After that, ensure that all permissions are given (if necessary, create a 'new share' with full permissions). Then go to security and ensure that everyone (including users) have full permissions to read and write. Do that to all directories and subdirectories. A very painful task but it works.
5. Delete eudora.log. If necessary delete descmap.pce (including in all sub-folders) and Linkhistory.dat etc.
6. DO NOT START EUDORA FROM THE ADMINISTRATOR ACCOUNT! ONLY FROM THE USER ACCOUNT.
