I have followed all of the instructions provided above. I’ve also tried restarting my computer more frequently—normally it remains on continuously—but this hasn’t produced consistent results. When the issue occurs again, a restart makes no difference. The situation is extremely frustrating. Re: MYOB AR - Email not sent - Unsupported Outlook Version - asking to switch to Outlook Classic Thank you ChrissyK1 that worked for today anyway :) Let's hope it's a permanent fix! Re: MYOB AR - Email not sent - Unsupported Outlook Version - asking to switch to Outlook Classic I’m reaching out again as the issue has reoccurred. After a brief success following the Office Quick Repair (which resolved the problem for just lot of emails), I’m now experiencing the same error message again. Since then, I’ve completed both a full Online Repair and a second Quick Repair, but unfortunately, the issue persists. I'm unable to send emails from MYOB to Outlook. Could you please advise on any further steps I can take to resolve this? Re: MYOB AR - Email not sent - Unsupported Outlook Version - asking to switch to Outlook Classic A quick repair has resolved my problem too. Thank you for your help. Re: MYOB AR - Email not sent - Unsupported Outlook Version - asking to switch to Outlook Classic After following the ChatGPT instructions, I realised I was still using the Classic version of Outlook—the toggle for "Try the New Outlook" was already set to off. I then launched MYOB as an administrator from the Start menu and attempted to send an email from MYOB to Outlook. Initially, I believed this was successful, as running it with administrator privileges prevented the original error message from appearing. Instead, I received the attached prompt asking me to allow each email individually. I clicked "Allow" for two emails, assuming they were sent successfully. However, upon opening Outlook, I found no emails in the Outbox (which is expected, as we use manual send/receive). I also checked the Sent Items folder in case the emails were automatically sent, but they were not there either. I have since logged out and back into MYOB (this time as a standard user, not an administrator), and I am now encountering the original error again: "Email not sent – Unsupported Outlook Version." Re: MYOB AR - Email not sent - Unsupported Outlook Version - asking to switch to Outlook Classic I used Mike's thought on ChatGPT and attempted to get AI to help me with my issue - For anyone else following along here is what AI had to say to the error message. This MYOB error occurs because New Outlook (Windows version) is not yet supported by MYOB for sending emails. MYOB relies on MAPI (Messaging Application Programming Interface), and the New Outlook for Windows doesn't support MAPI. 🔧 Fix: Switch to Classic Outlook To resolve this issue, you need to switch back to Classic Outlook, which does support MAPI and is compatible with MYOB. ✅ Steps to Switch Back to Classic Outlook: Open Outlook. In the top-right corner, locate the toggle that says: "New Outlook" or "Try the New Outlook" Disable the toggle (slide it off). You may see a message: “Switching will restart Outlook.” Click “Switch” to revert to Classic Outlook. Once Classic Outlook reopens, try resending the email from MYOB. 🧠 Why This Happens: New Outlook (as of now) is a modern, stripped-down version that lacks support for traditional Windows COM and MAPI protocols. MYOB depends on those protocols to send emails directly through Outlook. 💡 Alternative Workarounds (if switching isn’t possible): If you're stuck using New Outlook or you're on Outlook for Web or Mac, here are a few alternatives: Use MYOB’s built-in email option (if available). Export invoices as PDFs and manually attach them in Outlook. Set up SMTP email settings in MYOB to send via another service like Gmail or Outlook SMTP (this requires more setup and isn't available in all MYOB versions). Re: MYOB AR - Email not sent - Unsupported Outlook Version - asking to switch to Outlook Classic Thanks for your reply. We have trialled the option of sending emails directly from AccountRight, but unfortunately, it doesn’t meet our needs. We frequently need to CC individual remote staff members on invoice emails, and find this process much more efficient and flexible when using Outlook rather than MYOB’s built-in email system. Additionally, we have multiple users accessing the same online MYOB file and sending emails via Outlook without any issues. This appears to be isolated to a single computer, which suggests a localised issue rather than a broader compatibility problem. Given this, we would prefer to continue using Outlook and would appreciate your assistance in resolving the error we're experiencing with the New Outlook version. Looking forward to your guidance.
