In summary, to delete all messages in your inbox, you can select and delete them all at once or use the "clear all" or "empty" option. This can also be done for specific folders. Clearing your $MessageList will not delete sent messages and once cleared, the messages cannot be recovered. It is advised to double check before clearing to avoid losing important information.

You can unprotect it first:
Code:
Unprotect[$MessageList];
$MessageList = {};
Protect[$MessageList];

Thank you!
That's very handy to know -- there can be more use cases where the "protected tag" thing gets in the way.

1. What is the best way to clear $MessageList?

The best way to clear $MessageList is to use a loop to iterate through the list and set each item to null. This will ensure that all items are cleared from the list.

2. Can I use a built-in function to clear $MessageList?

Yes, most programming languages have a built-in function for clearing lists. Check the documentation for your specific language to find the appropriate function.

3. Will clearing $MessageList delete the messages?

No, clearing $MessageList will only remove the messages from the list. The actual messages will still exist in their original form.

4. How often should $MessageList be cleared?

This depends on your specific program and how frequently it uses $MessageList. If the list is used frequently and takes up a lot of memory, it may be best to clear it after every use. If it is not used often, clearing it periodically (such as once a day) should suffice.

5. Can I clear $MessageList without affecting other variables or lists?

Yes, as long as you only use the loop method mentioned in the first question and only target $MessageList, other variables and lists will not be affected. It is important to make sure you are only clearing the intended list to avoid any unwanted changes to your program.
