How do I re-enable automatic contact populating?

[Loki]

A few days ago (and 11 months prior to this), my Outlook would automatically
populate an email address I had used before when I entered the first few
letters in the "Send To" box. I have made no changes to Outlook, yet now it
does not remember any. I need to access these recent email addresses without
searching through the thousands of emails of I have. Any suggestions?

Click Tools>Options>E-mail Options>Advanced E-mail Options. Is the box
labeled "Suggest names while completing To, Cc, and Bcc fields" checked?

Yes, it indeed was checked. It's strange - today, all the email addresses
are back. I'm not sure why they were gone and then back again, but it seems
to be o.k. now. Thanks for the reply.
