As Pub 463 says "You must adequately account to your employer for these expenses within a reasonable period of time",  it depends on the employers rules as to what is adequate - eventually  your receipts did not meet their requirements.

The problem with that is it is an itemized deduction first reduced by 2% of AGI which probably makes it not deductible for most people.
