RE: search
Hi Ismail,
Thank you for your question.
If this number exist in one of your emails, locate the folder first. Then do the following:
In your Inbox or the mail subfolder, switch on Advanced Find (CTRL + SHIFT + F) and type in the number in "Search for the word(s)" box. Choose the "subject field and message body" option of the IN box. Then press "Find Now".
Kind regards,
Katie Woo
