Flow not trigger for old mails.

[kameshm]

I have developed a flow with "When a new email arrives in a shared mailbox"  to achieve save the attachment to SharePoint when moving email from inbox to a customer folder. It's working properly for newly arrived mails, But in the case of old mails, it does not trigger the flow. I don't know the what is the reason for not triggering old mails.

Is anyone face the same issue? I am stuck here for about 4 days.

Thanks in advance.

@kameshm ,

The trigger name is "When a new email arrives in a shared mailbox", so the flow will start only when a email is arrives. The old emails have already arrived and the trigger can't look into past action.

I'm not quite sure what you want to achieve, but I don't think that you can be done for old emails arrived in shared mail box.

@gabibalaban  Thanks.
  I shared the screenshot of my trigger.

In the folder input, I have entered the particular folder name that I want to trigger my flow. So this flow trigger when a new email arrives in my customer folder(i.e. Manually we move the mail from inbox to customer folder).
My question is this flow triggered as I said for today arrived mail, not trigger for yesterday or old mails.
