Combining multiple email accounts in Outlook can streamline communication and improve productivity by managing all your emails in one place. Manually, this process involves adding each account to Outlook via *File > Account Settings > Add Account*, then setting rules or creating folders to organize incoming emails. For combining data files (PST files), you need to go to *File > Open & Export > Open Outlook Data File*, then drag and drop emails or folders between accounts.
