How to fix "Error: QuickBooks is unable to send your email to Outlook"
I've done every step in the article multiple times. I can get it to work 2 or 3 times then it fails again. If I keep trying, I get an out of memory error and quickbooks closes down. I have Quickbooks enterprise 23. I've tried in single user and multi user mode. The only way I got it to work is setting my email up as webmail. The problem with that is it does not save a copy in my sent items. I can't get thunderbird to work. I've repaired Microsoft 365 and uninstalled and re-installed, ran tool hub, rebooted, uninstalled and re-installed quickbooks and updated. Ran all windows updates. It's on Windows 11. It used to work fine about 2 weeks ago. I am assuming it is some sort of update but I rolled back and still didn't fix it. Fixmapi.exe seems to do nothing. I renamed mapi32.dll to no effect. Frustrating to say the least.
