Solution 1Recommended

Clear Cached Exchange Credentials in Keychain Access

Deleting outdated or corrupted Exchange credentials forces Outlook to re-authenticate, which often resolves search and synchronization issues.

System upgrades can occasionally corrupt stored authentication tokens. Clearing these tokens from your Mac's Keychain is a safe and highly effective first step.

1
Close Microsoft Outlook

Ensure Outlook is completely closed. You can do this by clicking 'Outlook' in the top menu bar and selecting 'Quit Outlook'.

2
Open Keychain Access

Open Keychain Access on your Mac by searching for it with Spotlight (Command + Space) or by navigating to Applications > Utilities > Keychain Access.

3
Delete Exchange Credentials

In the Keychain Access search bar, type 'Exchange'. Locate the 'Exchange' or Outlook-related cached credential entries, right-click on them, and select 'Delete'.

4
Restart and Re-authenticate

Restart your Mac device. Open Outlook, sign in again when prompted with your email credentials, and test the email search functionality.

Clear Cached Exchange Credentials in Keychain Access
No Data Loss: Deleting cached credentials does not delete your emails. It simply forces the application to ask for your password again.

Frequently Asked Questions

Why did upgrading to macOS Ventura break my Outlook search?

Upgrading to a new macOS version can sometimes corrupt saved keychain credentials or disrupt the Spotlight search index that Outlook for Mac relies on to find your emails.

Will deleting Exchange credentials in Keychain Access delete my emails?

No, deleting cached credentials in Keychain Access only removes the saved login token. Your emails remain safely stored on the Exchange server, and Outlook will simply prompt you to enter your password again.

How do I know if my Outlook mailbox is still synchronizing?

You can check the synchronization status at the bottom right corner of the Outlook application window. If it displays 'Downloading' or 'Syncing', you should wait for the process to finish before attempting an email search.
