Hi @Office ，
It seems that you are encountering issue about add-in, please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client and know little about that. To better help solve your issue, I added the “Office-development “tag in your post.
Thanks for your understanding and hope your issue can be resolved.
