I have on my desktop a folder with 60.854 items in .eml-format, 5,59 GB.

In Windows Live Mail I have about 200 folders with on the average maybe 50 emails.

With the change from Outlook Express to WLM some four months ago and the change of hard disk and operating system to Windows 7 I had trouble to find out how to handle the new mailserver.

My problem now is the following. Most of the storage folders receive the moved emails alright, but ther is one batch of about fifty folders which all change a sent to them email to a standard content, while the time and sender of the email are kept alright.

I found already the advice to proceed as follows;

Depending on your version of the program, forcing a compaction of the database may help by re-indexing all your messages. This procedure is flaky, though, and may not work. Nevertheless, it's worth trying:

1. When viewing your message list, press Ctrl-Shift-O for Options.
2. On the Advanced tab, click Maintenance.
3. Select Compact the database on shutdown every... and change the number to 1.
   Close the options dialogue.
4. On the View tab, select Reading pane > Off to close it if it's open.  (This I failed to do!)
5. Click Work offline and disconnect from the network.
6. Disable any security software (e.g. anti-virus) that may be running.
7. Close down Windows Live Mail and leave it for several minutes. To be sure that you don't interfere with the process, start Task Manager (Ctrl-Shift-Escape) and wait until wlmail.exe disappears from the
   processes list before doing anything else.
8. Reboot the computer and check that your security software is running.
9. Launch Windows Live Mail again and try to view the messages that wouldn't display previously.

but that did not work.

I  am afraid the only straightforward solution is to replace all incorrect folders by new ones, applying a slight name  change.

Please, this gives me a headache already several days.
