My USA team member has send the Invite but we didn't receive any email. Is their any issue for sending Invite from one country to another country

Hi there, @kn99.

I'll help make sure you're able to receive the invitation email from a client in QuickBooks Online.

To get started, we haven't heard reports from other customers who are having problems with sending and accepting a user invitation email. Now, here are the common reasons why a certain user is having trouble accepting the invitation email:

• The email invitation might be in the junk email
• In the Company settings, the company email address is incorrectly formatted
• The recipient's mail servers might be blocking the email
• The invitation may have expired if it was not accepted within 2 to 5 days

Our troubleshooting will begin by adding the Intuit email address as one of your contact lists. This way, email messages from us will be recognized by your provider.

Aside from checking your Spam or Junk email folders, you'll also want to contact any local IT or your email domain provider and let a specialist turn off the sender ID filtering. By doing so, your email inboxes will not block or move our messages to the Spam folders.

Kindly read and share this article with your team member to learn more about the troubleshooting steps: What to do if Invited Users did not Receive your Email Invitation in QuickBooks Online?.

On that same page, I've also included this reference to get an overview of what you can do with the access given to you via the invitation email: User Roles and Access Rights in QuickBooks Online.

Let me know in the comments below if you've got questions about user management in QuickBooks. Don't forget to include my name, @JonpriL, in your reply so that I can get back here and continue working with you. Take care always, @kn99!
