What are MAIL3.ECF Error Messages?


General MAIL3.ECF Runtime Errors

MAIL3.ECF file errors often occur during the startup phase of Office, but can also occur while the program is running. These types ECF errors are also known as “runtime errors” because they occur while Office is running. Here are some of the most common MAIL3.ECF runtime errors:

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\Program Files\Microsoft Office\Office10\Addins\MAIL3.ECF

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.


Most ECF errors are due to missing or corrupt files. Your MAIL3.ECF file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Office), or deleted by a malware infection. Furthermore, MAIL3.ECF file corruption could be caused from a power outage when loading Office, system crash while loading or saving MAIL3.ECF, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Download MAIL3.ECF Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying MAIL3.ECF to your appropriate Windows system directory. Microsoft typically does not release Office ECF files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing MAIL3.ECF and all other ECF files for Office. An incorrectly installed ECF file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
