- Scenario
- Using Office 2019 applications after a system update that unexpectedly installed Microsoft 365.
- Observed behavior
- Bugs, pop-ups, and malfunctioning features like disappearing spelling suggestions occur due to system conflicts between Office 2019 and an unwanted Microsoft 365 installation.

Uninstall Conflicting Microsoft 365 and Repair Office 2019
Remove the unintended Microsoft 365 installation that is overlapping with Office 2019 to resolve software conflicts.
System updates or accidental prompts can sometimes install Microsoft 365 in the background. When both Microsoft 365 and Office 2019 are installed on the same machine, they frequently conflict, causing features like spell check to crash or disappear.
Click the Start menu, type 'Control Panel' in the search bar, and press Enter to launch the application.
Click on 'Programs', then select 'Programs and Features' to view a list of all software installed on your computer.
Scroll through the list to find 'Microsoft 365'. Right-click on it and select 'Uninstall'. Follow the on-screen prompts to completely remove it.
Locate 'Microsoft Office 2019' in the same list. Right-click it, select 'Change', and then choose 'Quick Repair' or 'Online Repair' to restore its proper functionality.

Install the Latest Office 2019 Updates
Update Office 2019 to patch known bugs and improve stability if removing Microsoft 365 does not fully resolve the issues.

Frequently Asked Questions
Why did Microsoft 365 install itself on my computer when I already own Office 2019?
Sometimes major Windows feature updates or accidental clicks on Microsoft promotional banners can trigger a trial or background installation of Microsoft 365. This causes overlapping registries and conflicts with your standalone Office 2019 license.
Will repairing Office 2019 delete my documents or custom settings?
No, running a Quick Repair or Online Repair from the Control Panel only targets corrupted application files and resets registry keys. Your personal documents, templates, and customized settings will remain unaffected.
How do I get my spelling suggestions back in Word 2019?
The disappearing spell check is usually a symptom of a software conflict. Uninstalling any overlapping Microsoft 365 apps via Programs and Features, then repairing Office 2019, will typically restore the missing spelling suggestions.
Where can I get advanced help if my Office 2019 bugs persist?
If standard troubleshooting fails, you can seek specialized assistance by posting your detailed issue in the Microsoft Office Management forum, ensuring you specify that you are using Office 2019 rather than Microsoft 365.
