You may be holding a small-sized business. You may be using both Microsoft Outlook and Yahoo mail. You may be thinking of some technique to merge them both. For the same, you will have to sync yahoo mail with outlook. This will be a smart idea, as you don’t have to individually see the email accounts of both Outlook and Yahoo Mail. You will have access to both Yahoo Mail with Outlook in one account. Importantly, communications in those accounts are kept separate so they don’t have to worry about their emails being mixed up. You will also have access to the appropriate emails, contacts, appointments, calendars, and much more through synchronizing.
