Question details

- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Composing a new email in Outlook and expecting recently imported Yahoo contacts to automatically populate in the address fields.
- Observed behavior
- The imported Yahoo contacts are visible in the Contacts folder but do not appear as suggestions in the To, Cc, or Bcc lines while typing.
Ensure that your Yahoo contacts were successfully imported from the CSV file and are fully visible in your Outlook 'People' or 'Contacts' tab before proceeding with cache resets.
Enable and Clear the Outlook AutoComplete List
The fastest way to resolve AutoComplete glitches is to ensure the feature is enabled in settings and then force it to rebuild by emptying the current cache list.
Sometimes the AutoComplete list becomes corrupted or is disabled after an update. Clearing the list forces Outlook to start fresh and rebuild the suggestions as you send new emails.
Launch Microsoft Outlook, click on the 'File' tab in the top left corner of the ribbon, and select 'Options' from the bottom of the menu.
In the Outlook Options window, click on the 'Mail' category in the left-hand navigation pane.
Scroll down the right pane until you reach the 'Send messages' section. Verify that the box next to 'Use AutoComplete List to suggest names when typing in the To, Cc, and Bcc lines' is checked.
If the box is already checked, click the 'Empty AutoComplete List' button right next to it. Select 'Yes' in the confirmation dialogue that appears, click 'OK' to save changes, and send a few test emails to rebuild your list.
Rename the RoamCache Folder
If emptying the AutoComplete list via the settings menu does not work, manually renaming the RoamCache folder will force Outlook to generate a completely new cache directory.

Frequently Asked Questions
Why do my imported contacts say 'This computer only'?
This happens when you import contacts into an IMAP email account. Because IMAP protocol only synchronizes emails and not contacts or calendars, Outlook saves your imported address book locally on your device rather than syncing it to the mail server.
Does AutoComplete pull directly from my Outlook Contacts list?
No, the AutoComplete list is functionally separate from your Contacts folder. It only stores email addresses that you have previously sent messages to, which is why newly imported contacts do not show up immediately.
How can I quickly add my imported contacts to AutoComplete?
You cannot instantly merge an imported CSV into the AutoComplete cache. You must manually select the imported contacts from your Address Book by clicking 'To' when composing an email, and send them at least one message. After that first email, Outlook will save them in the AutoComplete cache.
