I lost my email adresses when trying to go to send New Messages

[Jax]

When i go in my outlook and try to send a new message, it used to be that if
I type the first letter of the email, the rest or the different options of
all emails I have ever send, would appear. Now the y do not anymore. i lost
all my email adresses, They were not organized in categories either. What do
I do?

Outlook does not do this all by itself. List the steps you took just before
"used to." Include your Outlook version.
