How to Fix Missing Email Autocomplete Addresses in New Outlook
Question details
The user needs to restore missing external email addresses in the autocomplete list of the new Outlook.
- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Composing a new email and relying on the autocomplete feature to fill in external email addresses.
- Observed behavior
- External email addresses are missing from the autocomplete list in the new Outlook interface, but may still be available in the classic Outlook app.
Ensure you have a stable internet connection and try logging into Outlook on the web first to verify if your contacts are synced properly to your Microsoft account.
Add Missing Addresses to Contacts and Verify on the Web
Syncing missing external addresses via classic Outlook and verifying on the web helps isolate whether the issue is account-wide or app-specific.
Sometimes the new Outlook fails to pull recent external addresses that haven't been formally saved as contacts. Testing on multiple clients can help determine the root cause.
Launch the classic version of Microsoft Outlook on your computer.
Manually add the missing external email addresses to your Contacts list and save the changes.
Open a web browser, log in to Outlook on the web, and compose a new email. Type the newly added contact names to see if autocomplete works.
If autocomplete works on the web but not in the new Outlook app, the issue is isolated to the application itself rather than your account data.
Repair Microsoft 365 and Reinstall Outlook
If the autocomplete issue is isolated to the new Outlook application, repairing the installation or reinstalling the app can fix corrupted files.
Try WPS Office as Your Reliable Office Suite Alternative
If you are experiencing frequent synchronization or application errors with Microsoft 365, consider trying WPS Office. It provides a lightweight, comprehensive suite for document editing, spreadsheets, and presentations, with excellent format compatibility and a user-friendly interface.
Frequently Asked Questions
Why are my autocomplete email addresses missing in the new Outlook?
This can happen due to a synchronization glitch between the new Outlook client and your Microsoft account, corrupted application files, or a localized cache issue specific to the new Outlook app interface.
How do I clear the autocomplete cache in Outlook?
In classic Outlook, you can clear the autocomplete cache by navigating to File > Options > Mail, scrolling down to the 'Send messages' section, and clicking the 'Empty Auto-Complete List' button.
Does the new Outlook share the same autocomplete list as classic Outlook?
The new Outlook aims to sync with your account's cloud-based contact list, but caching differences and beta features can sometimes cause temporary discrepancies between the new Outlook and classic Outlook's local autocomplete list.
What should I do if repairing Microsoft 365 doesn't fix the issue?
If repairing the suite does not resolve the missing autocomplete addresses, you can try completely uninstalling the new Outlook app from your system and downloading a fresh version from the Microsoft Store. Additionally, submit feedback through the Outlook Help menu to alert Microsoft of the bug.
