How to put back the emails to the gmail account?

[PiX3L]

Hello everyone!

 

I tried to configure the mailing system in the PrestaShop and something went wrong.

When I tried connect/log in with my gmail account, the mailing system put all the incoming mails into the PrestaShop and deleted my mails from the gmail account.

 

Now I need your help. Is there any possibility to put it back or do something to see those mails in the gmail account?

 

I'm not very good in English, but I tried to use the Google to find any option to my problem and I found nothing. I realy need your help to solve this problem.

 

Thank you all of your help!
