Any updates to this?  I am having the same issue as everyone else and this is an issue only when trying to send any sort of document from Quickbooks.  It shows as a draft in my email that has no option to send it unless I revert back to the old Outlook.  There is definitely a configuration issue going on in my opinion and come 2024 we won't be able to use the oud outlook.  If this isn't resolved by Quickbooks by then I will have no choice but to find a new program for my buisness.
