Use PowerShell to Send Messages from Shared Mailboxes, Groups, and Distribution Lists
Everyone probably knows how to use Exchange's Send As and Send on Behalf of permissions to send email from user mailboxes. Here we venture into the same task, but for Microsoft 365 Groups, shared mailboxes, distribution lists, and mail-enabled security groups. Once your permissions are aligned, everything is pretty simple. https://practical365.com/sendas-send-on-behalf-of-mail-objects/
Share user's mailbox: Default 'send from' address? and default sent folder?
Hi, In an instance whereby a user's mailbox (say user1@contoso.com) is shared with user2@contoso.com with 'Full Access' and 'Send as' privileges. There seems to be two issues: Whenever, user2@contoso.com replies to emails sent to user1@contoso.com, the 'send from' address is user2 instead of user1. And the replied email is only stored in the sent mailbox of user2 and not in user1. How can both these issues be fixed? Thanking you in advance, Note: Using OWA and Exchange Online
