outlook 2011 Macintosh, abbreviations mfg –> mag

Hi all,

i have a mac osx 10.11.1, and outlook 2011.

When editing a new mail, i can enter the text " mfg " and it will be changed every time to " mag ".

I have searched in Outlook, i found no abbreviation / shortcut list.

I have searched in Office word, there is a shortcut list which changes " mfg " to " Mit freundlichen Grüßen ".

I have searched in osx settings, there is no shortcut for " msg ".

So why is Outlook 2011 Macintosh always changing mfg to mag? Where must i search?

greetings from germany

Chris
