Microsoft will not provide any support for Windows XP SP3 and Office 2003 after April 8, 2014 means user can not get security patches, non-security hotfixes or incident support for these products. Personally i am sad after reading this news. I have just finished one of the project that based on Outlook 2003.
Without support users can face the following problems:
