Frequently Asked Questions

Can I edit Google Docs directly in Microsoft Word?

Not directly in their native format. Google Docs would need to be converted to a compatible format like DOCX first. When using integration methods like Google Drive for Desktop, you can open and edit the converted files in Word, but some formatting might change during conversion. For the best experience, consider saving Google Docs in Microsoft formats when planning to edit them in Office applications.

Will file transfer permissions when syncing between Google Drive and Office 365?

No, permissions don't automatically transfer between the platforms. Each service has its own permission system, so you'll need to set up sharing settings separately in both Google Drive and Office 365. Some third-party integration tools offer permission mapping features, but these typically require additional configuration and may not support all permission types.

Is there a storage limit when connecting Google Drive to Office 365?

The storage limits of each service apply independently. Connecting the services doesn't provide additional storage space – you're still bound by your Google Drive storage limit and your Office 365 storage allocation. Files synced between services count toward the storage quota on both platforms, so you're effectively using double the storage for synchronized files.

Can I use these integration methods on mobile devices?

It depends on the method. Google Drive for Desktop is primarily for computers, while third-party tools like MultCloud often have mobile apps or responsive web interfaces. Power Automate flows work in the background regardless of device. For mobile-specific integration, look for third-party apps designed for mobile platforms or use the web interfaces of integration services through your mobile browser.

What happens if I delete a file from one service after integration?

The behavior depends on your integration method and settings. With two-way sync, deleting a file in one location typically deletes it from the other. With one-way sync, deletions may or may not propagate depending on your configuration. Some tools offer "trash protection" to prevent accidental deletions from affecting both services. It's important to understand your specific integration's behavior and configure deletion settings according to your needs.
