Question : How to update all records except for current day within Microsoft Access query?

I have the following SQL syntax.  How may I change it to update all records except for todays date?
The OutDate is obviously a date field that contains Now() information - Day, Month, Year and Time.
It is impossible to have a row without an InDate - so I definitely could use that field as a criteria to see if its todays date - I'm just not familiar with the proper SQL syntax to put in the criteria!

Some examples of InDates:
7/15/2010 3:23:18 AM
7/15/2010 1:16:56 AM
7/14/2010 11:01:10 PM

Thanks in advance!

UPDATE Access_LOGGER SET Access_LOGGER.OutDate = [InDate] WHERE (((Access_LOGGER.OutDate) Is Null));

Why are you deleting data that other tables depend on?  Don't you have any referential integrity set up (like foreign key constraints)?
