I have created a Microsoft 365 group for sending and receiving mails to external clients. But am unable send mails from that email account and also unable to delegate this access to anyone in the team. Tried following all articles but the option of delegating access of "send as" does not come. how to access the common shared mailbox also (in an article it mentions that a Microsoft 365 group also provided a shared mailbox, do I need to create it or how to access it if it is already created?)
