    *For Germany:
      *"Systemsteuerung" or MSIE11.
        *"Internetoptionen / Programme - Internet Explorer wird geöffnet" - "Internet Explorer als Standardbrowser einrichten".
  *As of 2018-05, most Internet websites refuse to communicate with MSIE6 of W2k, as they require SSL connections. 
    *MSIE6 just supports SSL2.0, SSL3.0, TSL 1.0 :-(.
    *If you enter "apple.de", the MSIE6 browser just loads BING, searching for "apple.de" :-(.
    *Just a few sites which don´t requre SSL, are loaded properly, e.g. [[http://hemmerling.free.fr/|hemmerling.free.fr]].
    *See:

    *Newspaper 06/2022, page 11, article "Open Source. Linux im Public Sector" - "Als zweite Herausforderung wird eine alternative Groupware genannt. 'Microsoft Outlook' hat sich längst zum Standard entwickelt. In der Studie wird empfohlen, die Umstellung der eMail und Groupware-Applikation im Rahmen einer Umstellun  des eMail-Dienstes auf ein Open-Source-Produkt durchzuführen. Aber: **'Problematisch bezüglich der Nutzung von MS Exchange als eMail-Dienst in Kombination mit einer anderen Open-Source-Mail-und-Groupware-Applikation ist das lizenzrechtliche Verbot innerhalb der USA, das von Microsoft patentierte ActiveSync-Protokoll in Open-Source-Anwendungen zu implementieren'. Aus diesem Grund gebe es keine Open-Source-eMal/Groupware-Client-Applikationen, die man gegen einen MS-Exchange-Dienst verwenden könne**. Problematisch sei diesbezüglich auch, dass für eine Outlook-Ablösung nicht nur das Mailprogramm ersetzt, sondern auch das vollständige Mail- und Kollaborationsbackend MS Exchange durch eine andere Software abgelöst werden müsse".

        -Unselect "[ ] Leave messages on server".
      -"Composition & Adressing".
        -Unselect "[ ] Compose messages in HTML format".
      -Press button "Ok".
    -Step 2:
      -Open the just created profile by mouse-rightclick.
      -"Server Settings".
      -"Local directory": Press button "Browse" and select the existing mail directory for the account.
      -Press button "Ok". 
      -Thunderbird asks you "Thunderbird needs to restart to apply the change of the Local directory settting". Press button "Restart".
  *The motivation: 
    *During a recent installation of Thunderbird 31, 
      *I selected by error a IMAP account for testing my E-Mail provider account :-(, 
      *without deactivation of the message download option :-(,
      *and then ( see step 2 ) I selected the existing POP3 mail directory for the account as new local directory.
    *The effect was that my "Sent" directory and a few other directories were emptied :-(, if I remember right the "failure of filtering" bug appeared during the download. But Thunderbird definitively wiped out the contents of some email subdirectories by own activity :-(.
=== "AppHangB1" with Thunderbird ===
  *After new installation of Windows and installation of Thunderbird 31, including the creation of a new Thunderbird user profile, Thunderbird did not work properly, but Windows told me that Thunderbird is in [[http://www.google.de/search?q=AppHangB1|Google "AppHangB1"]] mode. The application was not usable, after 1 or 2 mouseclicks it "hanged" and just showed the Windows sandmill.
    *It did not help to deinstall and reinstall neither Thunderbird 31 nor 24.01 - The "hanging" happended every time.
    *Thunderbird 17 installed properly, but was not able to use the Thunderbird 31 & 24.01 profile properly - so it did not display the mail folders, though it knew about the account.
    *The only help was to delete the Thunderbird profile - the "hanging" did not appear again neither with Thunderbird 31 or 24.01.
=== How to delete a Thunderbird Profile ===
  *[[http://kb.mozillazine.org/Profile_folder_-_Thunderbird|MozillaZine "Profile folder - Thunderbird"]] - "You can also navigate directly to your profile folder at the following path: C:\Users\<Windows user name>\AppData\Roaming\Thunderbird\Profiles\<Profile name>".
  *[[http://forums.mozillazine.org/viewtopic.php?f=39&t=2610971|MozillaZine Forum "Your Thunderbird profile cannot be loaded"]].
    *"Your best bet might be to delete the profiles.ini file for Thunderbird (make certain you don't delete the one for Firefox instead)".
    *C:\Users\<Windows user name>\AppData\Roaming\Thunderbird\Profiles\profile.ini".
=== Thunderbird: Sending E-Mails by SMTP fails ===
  *Error message while sending an E-Mail by SMTP, by E-Mail provider GMX:<code>
An error occured while sending mail. 
The mail server responded: 5.7.0 Authentification expired (mp016). 
Please check the message and try again.</code>
  *Solution: Login at the Web portal of GMX. GMX suspended your account ( due to a login attack attempt ) and asks you to setup a new password, by the Web portal. After that, with new password, E-Mail sending works again.
=== Thunderbird: Restoring messages from .mozmsgs Folder ===
  *Keeping the default option "Allow [your OS's search engine] to search messages" creates a backup of Thunderbirg messages, in extra subdirectories, but in the same file system path. You may later import these messages into Thunderbird, if necessary.
  *[[http://www.getsatisfaction.com/mozilla_messaging/topics/_sbd_and_mozmsgs_files_reappearing_on_hd|Getsatisfaction - Thunderbird "*.sbd and *.mozmsgs files reappearing on HD"]] - "The .mozmsgs directories store data that allows Windows Search or Spotlight to index your mail folders. They are filled up if you let your computer remain idle for some time and keep Thunderbird open. You can easily turn it off from Tools-Options or Preferences, in the Advanced pane, General tab. You'll find a checkbox saying 'Allow [your OS's search engine] to search messages'".
  *[[http://forums.mozillazine.org/viewtopic.php?f=29&t=1230495|Mozillazine "recover lost emails from Inbox.mozmsgs folder"]], 2009-05-04.
    *"I copied the missing files from the *.mozmsgs folder in my profile to a new folder. Used the command prompt to change the file extension from .wdseml to .eml and then used Import/Export Tools Add-On to import the missing messages back into Thunderbird" :-).
    *"It should be noted that the wdseml files do not contain any attachments that may have been part of the original message" :-(.
=== Thunderbird 24.1.0 .. 24.5.0..?: Failure of Filtering ===
  *Error message when receiving E-Mails and sorting it into folders according to filter rules:<code>
The messages could not be filtered to folder '%S' because writing to folder failed. 
Verify that you have enough disk space, and that you have write privileges to the file system, 
then try again</code>
  *[[http://bugzilla.mozilla.org/show_bug.cgi?id=931303|Bugzilla@Mozilla "Bug 931303 - message could not be filtered to folder because writing to folder failed"]].
  *[[http://download.cdn.mozilla.net/pub/mozilla.org/thunderbird/releases/24.0.1/|Thunderbird 24.0.1]] is currently the latest stable release, as of 2014-05, without this bug.
  *Tip: If you switch back from Thunderbird 24.5 to 24.0.1, please compress all folder data by Thunderbird itself, to get rid of the bug.
