Add-ins are not visible for Shared Mailbox and it is accessible only for Primary mailbox. Would be great to be able to use add-ins for Shared Mailbox also.
We have been using template with our shared mailbox for 2 years and today it doesn't work anymore for no reason. We are a company and we write a lot of mails everyday and having templates is a must have foir any companies.
A solution should be found asap please
