A few of our employees (Org A) work for Org B. Org A (we) have Office 365 and Org B has hosted MS Exchange 2010. Our employees would like to access and also SEND emails from OWA with alias of Org B. This can be done using connected accounts. However, Org B refuses to support POP or IMAP with the Exchange.
How our users can connect to Org B email account to send and receive emails?
Is there a buffer medium that can be used to solve the case?
Thank you all!
