Upgrade to Microsoft 365 and Add Your Work Account

Uninstall the outdated Office 2016 software and use your personal Microsoft 365 subscription to sign in, then add your work account to enable AutoSave and corporate file syncing.

AutoSave is exclusively supported when using a Microsoft 365 subscription and saving files directly to OneDrive or SharePoint. Office 2016 does not support this feature.

You can leverage your personal Microsoft 365 subscription for the core Office applications, while adding your work credentials to access business files.

1
Uninstall Office 2016

Open the Windows Control Panel, navigate to Programs > Programs and Features, locate Microsoft Office 2016 in the list, and select Uninstall.

2
Install Microsoft 365 Apps

Log into your personal Microsoft account at Office.com, download the Microsoft 365 installer, and follow the on-screen prompts to install the updated suite.

3
Sign in with Personal Account

Launch any Office application such as Word or Excel, and sign in using your personal Microsoft 365 subscription credentials.

4
Add Work Account

Click on File in the top ribbon, select Account (or Office Account), and under Connected Services, click Add a service > Storage > OneDrive for Business. Enter your work credentials.

5
Enable AutoSave

Open or create a work document and ensure you save it to the newly added business OneDrive or SharePoint location to automatically enable the AutoSave toggle.

Frequently Asked Questions

Why isn't AutoSave working on my Office 2016?

AutoSave for cloud files is a feature exclusive to Microsoft 365 subscriptions. Office 2016 does not support this feature, which is why you must upgrade to Microsoft 365 and save your files to OneDrive or SharePoint to use it.

Can I be signed into both personal and work Microsoft accounts at the same time?

Yes, Microsoft 365 apps allow you to add multiple connected services. You can sign in primarily with your personal account and then add your work account via File > Account to access files from both cloud locations.

Where are my synced work files stored?

When you use a work account, your synced files are securely stored in your organization's OneDrive for Business or SharePoint Online, keeping them separate from your personal cloud storage.

What should I do if my work account cannot be added to my personal Office app?

This usually happens due to your company's IT security policies restricting access on unmanaged devices. You will need to contact your IT administrator to request access or obtain a dedicated business software license.
