remove the primary account from Outlook

If you’re looking for a new Outlook guide to help you change or remove your primary account, you’ve come to the right place. Any user enjoys the freedom to add two or more accounts in the Outlook e-mail application.

It makes perfect sense to get all your mails in a single application, right? However, the first account added remains the primary account. So, you’ve got a problem on your hands when migrating from one Exchange service to another.

Outlook informs you that The primary Account cannot be removed unless it is the only account in profile. You must remove all other Exchange account before removing primary account. Ideally, a new data file should override the old primary account preference, but this doesn’t happen.

If you are wondering how to change or remove the primary account from Outlook, just follow the procedure below to understand how it works.
