If you are a Microsoft 365 user you can easily see what your default storage is by visiting your online account at portal.office.com and navigating to your OneDrive account then select Storage in the left-hand navigation pane.

This will show you your default storage for OneDrive under your Office 365 account.

If you are having issues when trying to output your template while that template is saved into a OneDrive directory then you can do one of two things.

Upgrade the storage associated with your Office 365 account or simply move your Windward templates into a directory outside of your OneDrive directories and this will overcome any exceptions you are encountering.
