Re: eMail Invoices
These solutions have been tried as requested by Enterprise support. None fix the issue. Most of what you mentioned in your reply was addressed in the original inquiry and did not work either. The mini repair and the full repair AND the full uninstall and reinstall did not remedy the situation.
And as I mentioned in the original post, this was all working before and continues to work intermittently so it was obvious that we are using Outlook 365 Desktop or it would not be working at all.
I am an IT admin so like I said, after the Windows 10 1903 update is when this started. Quickbooks developers need to take a look at how Quickbooks interfaces with the OS since this latest update. I imagine there is something that they missed or Quickbooks needs a patch to make this work without fail again.
