Can I change my receipt forward address more than once and is there a wait time in between changes?

I've got you covered, Bookkeeper Amongst Other Things.

I'd suggest going to the Manage forwarding email section to see if you have the Update button. If so, please click on it, and then enter the correct email address. Here's how:

1. Go to the Banking menu or Transactions menu.
2. Select the Receipts tab.
3. Choose Manage Forwarding email.
4. Click Update and then add the new email. It will have @qbodocs.com at the end.
   
5. The email will be updated immediately.
6. After confirming the changes, click close.

If the Update button is no longer available, I'd recommend contacting our QuickBooks Support Team to check if they have an option to update your email address.

Additionally, I've added these articles that'll help you upload, send and categorize your receipts in QuickBooks Online:

• Email receipts and bills to QuickBooks Online
• Upload your receipts and bills to QuickBooks Online
• Categorize and match online bank transactions in QuickBooks Online

Please come back and keep us posted on your progress in updating your email address, Bookkeeper Amongst Other Things. I'm determined to get this resolved.

Hi Bookkeeper Amongst Other Things,

Hope you’re doing great. I wanted to see how everything about updating your forwarding email address in QuickBooks Online. Do you need any additional help or clarification? If you do, just let me know. I’d be happy to help you at anytime.
 
Looking forward to your reply. Have a pleasant day ahead!

So, changing your receipt email is available to change more than once.  You just have to wait a few days for the timer to run out and then the update button reappears.
