Updating QuickBooks Desktop to the latest release can help resolve QuickBooks error code 350 with a secure bank connection.

3. Reconnect your bank and credit card account

• Open QuickBooks Desktop. 
• Look for recently categorized transactions.
• Note down the transaction date. 
• Follow the on-screen steps to import your QuickBooks data. 

Note: Be sure to complete this step before connecting your bank. Otherwise, your Desktop data will overwrite any bank transactions downloaded into QuickBooks Online.

• To link your bank account to QuickBooks Online, follow the steps in the Intuit article. To prevent duplicate transactions, import transactions only from the date specified in Step 2. You can adjust the transaction start date during the bank connection process.

4. Use the QuickBooks Tool Hub

Let’s use the QuickBooks Tool Hub to access various tools and utilities to resolve common company file and network connectivity issues that can cause the QuickBooks bank connection error 350:
