To integrate Google Apps Drive accounts with Office 365 OneDrive accounts or just sync them, you need to create two-way sync pairs like this:

Google Drive (bob@acme.com) <->  Office 365 OneDrive (bob@acme.com)
Google Drive (alice@acme.com) <-> Office 365 OneDrive (alice@acme.com)
...

The above will create a two-way sync of each Google Drive account with a corresponding Office 365 OneDrive account. The data will be kept in sync and any changes will be replicated.

cloudHQ will also replicate all sharing information and permissions from Google Drive to Office 365 OneDrive.
