Windows Live Mail (WLM) can be used on XP, Vista, and Windows 7.
To transfer WLM and associated data between two machines do the following:
1 -Iinstall Express Assist 10 (EA10) on the first machine
2 - Make a backup copy of the WLM mail folders, data base and settings
3 - Save the backup to some media that can be used on the second machine
4 - Make sure that WLM is installed and configured for use on the second machine.
Hint - you can configure WLM without downloading email by ensuring that the machine is not connected to the Internet while WLM is being configured.
5 - Install Express Assist 10 (EA10) on the second machine
6 - Run EA10 and select "Restore"
7 - Locate the backup from step 3 -- "Open" it
If the second (target) machine is Vista or Windows 7 - then proceed with step 8.
If the target machine is XP and the first (source) machine was Vista or Windows 7 - then proceed with step 11
8 - Click the "Restore All Mail Folders......" function
9 - Select the "Windows Live Mail" group and all of the Windows Live Mail items -- as shown below:
10 - Finish the Restore.
11 - Click the "Restore all Email Folders for Import" function
12 - Select the "Windows Live Mail" group and all of the Windows Live Mail items
13 - Run WLM on the target machine
14 - Go to menu "File" - "Import" - "Messages"
15 - Select the messages to import "Windows Live Mail" -- Next
16 - Click the "Browse" button to locate the folder shown in the Restore Log. Select this folder.
15 - Finish stepping through the message import wizard to import the mail.
Notes:
The import process will place the imported mail folders under an "Imported Folder" in WLM. That is, the source Inbox messages will not appear in the standard WLM Inbox, etc. This is not a bug in EA10. This is just how the Windows Live Mail handles the import.
