How to: Enable IMAP extension for PHP on Windows?

Open your php.ini file. Search for 'extension_dir' and add the path of your ext directory in there. For example : extension_dir= 'C:/php/ext/'. If this line has been commented out, please un-comment the line (by removing the semi-colon ';' from the beginning of the line.

Check if you have php_imap.dll on your C:PHP/ext directory (path to PHP). If yes, un-comment the following line in your php.ini. "extension=php_imap.dll".

Though a restart is not neccessary, some systems require a restart for the settings to take effect.
