Windows Live Mail email client does not delete messages by itself.
Messages are deleted only when
- User deletes them
- User changes default settings
- Message is deleted on server (IMAP)
- Settings on email service provider's server are set to delete messages per instructions (IMAP); messages will also be deleted on WLM client due IMAP folder synchronization
As you did not tell what email provider you are using and if you use
IMAP or
POP3 mail protocol, it is impossible to say why your old messages have disappeared. Read more about IMAP vs. POP3:
Email: What's the Difference Between POP3, IMAP, and Exchange? - How-To Geek
Short explanation:
POP3 stores the messages both locally and on server if the option
Leave the copy of messages on the server is chosen. This is not synchronized; a message deleted locally is not deleted on server, neither is a message deleted on server deleted from your computer. If the option is not selected, messages are deleted from the server when Live Mail (or any other client) has read them.
IMAP stores the messages both locally and on the server, doing this in a synchronized way: if the message is deleted locally in Live Mail, it is also deleted from the server, and vice versa.
When using
IMAP, a deleted message remains in
Deleted Items folder on WLM, and in
Deleted folder on server (the name in Hotmail / Live, other service providers might have a different name for this folder on server). It is only completely removed when it is deleted from this folder, not before, for instance when you empty the
Deleted Items folder on your mail client. When this is done, it will be removed from the client (WLM) as well as from server because one of the most characterizing features of IMAP is that it keeps both mailboxes synchronized, the one on your client (WLM or any other mail client) and the one by your service provider's mail server.
To change this default setting, go to
File > Options > Mail, select
Advanced > Maintenance and select
Empty items from "Deleted Items" folder on exit. This will remove all deleted messages completely every time you exit WLM:
POP3 mail protocol allows you to have totally independent mailboxes locally on your client and on the server. To change POP3 settings to keep or delete messages on server, go to
File > Options > Email Accounts, select your POP3 account and click
Properties and change the delivery settings as you wish:
I recommend you to check your mail settings on your service provider's webmail interface. For your issue the reason for disappeared messages is either a user setting, your mail provider's settings on server or that you have deleted the messages yourself, with or without intent.
