Can't Email (Outlook) InDesign CS2 "Lock"(?) File

[BoSoxRox]

I did a layout in InDesign CS2, saved it (.indd) then I wanted to email it...simple? Apparently not!

Using Microsoft Outlook...I click "New Message" enter the email address, then click on the paper clip icon to attatch my file. I browse for the file (using thumbnail vire), when I locate my InDesign File it has a picture of a padlock over it...if I hover over it with the cusror it says.."InDesign Lock File" (???) I double click on it to attatch it and I get a pop up error message "This operation can not be performed". I did not Intentionally "Lock" this file. So I opened up InDesign and attempted to "save as..." to see what my options were.. nothing relating to locking the file... the layers are not locked...I am stumped..

Anybody??

Thank you!

UPDATE:

Somethings are so simple they escape you!...I was trying to email it while I still had the file open in InDesign.... Did not even think about it.... Sorry about the wasted post!
