I'm working with Outlook 2016 and I'd like to display multiple mailboxes (.pst or .ost) simultaneously on the left pane. I have set up for a user multiple profiles attached to different mailboxes.
When the user starts the Outlook client it prompts to select a profile and the mailbox, and only this mailbox, is loaded and displays on left pane.
Is there a way to display all mailboxes in left pane? I appreciate any guidance. Thank you.
