I ran an automatic routine for getting the specification of the desired email.
I should mention here the email was an IMAP email type.
Then, I get the ports numbers of IMAP email type in my mail-server (incoming=SSL 995 and outging=SSL 465).
And then, I ignored the final step and I canceled the procedure.
Then I started for making a new account (based on the desired email) but manually.
In the windows for inserting the details of wanted email, I mentioned POP3 type for the email. then I could set the existing datafile (.pst) for using as a necessary datafile for this email.
but before going to the final step (pressing "Next" button) I went to "More Setting ..." and in "Advanced" Tab, I did set the incoming & outgoing port numbers with the specified details (incoming= SSL, port no.=995 & outgoing=SSL, port no.=465)
Then I went to the "Outgoing Server" Tab and tick the "My outgoing server (SMTP) ..." for using same incoming server setting for it.
Then I did click the "OK" button and then click the "Next" button.
Then I should wait for complete the "Test Account" procedure. Now I have a new email account with using the old .pst datefile.
After the completion of the setting for a new account, maybe the account does not show the new emails.
