If you're still experiencing performance issues with Word, ensure you're using the 64-bit version of the application. Other users have reported similar problems with Microsoft Office on their Macs running High Sierra.

To resolve Outlook freezing issues, try resetting your preferences using the 'Outlook Reset Preferences' tool:

1. Open Terminal (located in Utilities or LaunchPad) and type 'kill all cfprefsd' without quotes.

2. Press Enter to execute the command.

3. Type 'defaults write DisablePreviewForSMIME 1' without quotes and press Enter.

Once you've applied these steps, restart Outlook and check if the freezing issues have been resolved.

If not, you can try updating your Office software by following these steps:
