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.

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?

Hi Caitlin,

I uninstalled the new outlook app before I did the office quick repair and we are not having any more problems with emailing via outlook.

Thanks ChrissyK1​ good tip!

Thank you ChrissyK1​ that worked for today anyway :) 

Let's hope it's a permanent fix! 

Hi Caitlin

Having this problem too. Were you able to resolve this and if so how?????????

At this point, the system will function correctly one day and then fail to send for the next week or more, then randomly works one day and then stops again; and I’m unsure why. 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.

Try uninstalling the new outlook and then do the repair as below from Mike - this worked for me

 if you are receiving this message but you actually use Outlook classic, as part of a desktop installation of Office 365, then possibly running a "quick repair" of Office may help, or a full "Online repair" (which will take longer).
