Baidu CEO Robin Lee write a post Should we provide Email service today,saying:

Baidu do not provide email services because they feel prevailing email services are good enough.But honestly,he is still using Outlook to receive mails,which aways reminds him to save the archives in case of loss.Unfortunately,due to the limitation of 2G storage of Outlook,he complained that he's lost emails many times in the past few years.So if they launch Email service,that service must provide unlimited storage.
