Once finished, Outlook will restart. The new account becomes your primary one. Your old emails will remain, but your calendar and contacts will now sync with the new primary account settings.

Summary
To change your primary account in Outlook, the method depends on whether you're using the New or Classic version.
Can I change the primary account without deleting the profile?
In the New Outlook, yes, you can switch it via settings. In Classic Outlook, you generally cannot change the primary account without creating a new profile, as the primary account is hard-coded to the profile creation sequence for Exchange accounts.
Why is my primary account grayed out in Outlook?
If the option is grayed out, it is because that account is currently the primary identity for your profile. Outlook requires one primary account to manage the data file location and privacy settings, so it cannot be removed or changed while it is in active use.
Does changing the primary account delete my old emails?
No, changing your primary account does not delete your old emails. Your existing .pst or .ost data files remain on your computer. However, you may need to manually add your old data files back into the new profile to see your archived messages.
