RE: Outlook 15.3 crashes

Hi Toshi,

Thanks for your post with the detailed information.

I would like to explain that it is an Outlook for Mac client related issue. Although we’d like to assist you, we are not masters of this field (we are dedicated to Office 365 service in this forum).

Therefore, to get the issue handled more effectively, I'd like to recommend you post a new thread in our Outlook for Mac forum. This is a specific support channel which is dedicated to helping users with Outlook client issues. The engineers there have sufficient experience and they will be glad to assist you.
    
Your understanding will be highly appreciated.

Thanks,
Richard
