Personal Email Account

Hello Everyone ,
Please can someone explain to me the role of a personal mail account in suitecrm?
I couldn’t set up a personal email acccount since my email address is generated by a central server and therefore i can’t see exactly how will this personal email account help me.
What i have read till now is that , this personal email account helps to show the emails that i receive on my mailbox (in my case outlook) . When these emails are shown in the module of suitecrm i can then import it manually and associate it to a contact or account.
Is there anything more to know about this ?
Thanks in advance

A personal email account is an internal or external email account used to view and send personal emails from the Emails Module.
