Contact groups are in address list but wont show up in address bar

lozza_dearnley Hi all so I figured it out, I think Outlook only remembers a certain number of email addresses and over time they have just accumulated so the ones I need are being forgotten.

Here's how I fixed it:

Go to File / Options / Mail / Send Messages

Click 'Empty Auto-complete list' and make sure it is ticked

This deletes all the autofills but the email addresses stay in your address book

Open a new email, press 'To', select all the addresses you want to autocomplete, and hit 'enter' 

This will add them all to the 'To' section and to Outlook's memory so when you start typing the persons name (or in my case, the address), they will pop up ready for selection.

Seems to be working so far, hopefully I am able to help someone else with this issue!
