Stream_ContactPrefs_2_CECA1B76E0A3944D909696C17A9EF949.dat is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Stream_ContactPrefs_2_CECA1B76E0A3944D909696C17A9EF949.dat, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like BCSSync.exe - to follow. These files were created so that multiple programs (eg. Microsoft Office Outlook 2010) could share the same Stream_ContactPrefs_2_CECA1B76E0A3944D909696C17A9EF949.dat file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DAT file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when Stream_ContactPrefs_2_CECA1B76E0A3944D909696C17A9EF949.dat is attempted to be loaded either when Microsoft Office Outlook 2010 is starting up, or in some cases already running. Some of the most common Stream_ContactPrefs_2_CECA1B76E0A3944D909696C17A9EF949.dat errors include:
