I am running Windows 7 and Windows Live Mail (WLM) 2012 on an Acer Aspire laptop.

One of my email folders contains 2,121 email messages. As you know, they are named such as "76047268-00000054," which means nothing to me. Will it cause problems to WLM if I rename the file to something relevant to the message and that I can quickly identify (e.g., birthday wishes 2014)?

Thanks.
