Frequently Asked Questions

Can I keep both my personal Office and work Microsoft 365 installed on the same PC?

Installing multiple versions of Microsoft Office on the same computer frequently causes file association conflicts and activation errors. It is strongly recommended to keep only one installation and switch accounts within the application, provided employer policies allow it.

Will uninstalling Microsoft 365 delete my saved Excel files?

No, uninstalling the Microsoft 365 applications from the Control Panel will only remove the software programs. Your saved documents, spreadsheets, and personal files will remain safely stored on your local hard drive.

How can I access my employer's files without installing their desktop software?

To prevent altering your personal desktop installation, you can use Excel Online via a web browser for temporary work tasks. Simply log in to office.com using your employer-provided credentials to access and edit work files online.
