QBDataServiceUser

Ensuring the smooth operation of all QuickBooks services and integrations is our utmost priority, Terri.

QuickBooks Data Service User accounts are created automatically by QuickBooks Desktop to manage database connections and services. If you have installed upgrades to QuickBooks over the years there could be a user account and folder for each upgrade you installed. 

If you uninstalled an older version of QuickBooks Desktop (QBDT), then those lower-numbered QBDataServiceUser accounts are no longer being used. In this case, you don't need all three accounts. You can safely delete the folders with the lower numbers, keeping only the one with the highest number in place.

I've added this article on how  QuickBooks Data Services works and how to contact support: QuickBooks Data Services FAQ.

I'm always prepared if you have more questions or concerns with the QuickBooks Data Service account. Kindly leave a comment below, and I'll promptly lend a hand.
