Conditional Formatting Table

I have a large table in Excel that includes the columns "Desk" and "Date". I would like to highlight all rows where there are duplicate desks per date.

 

E.g. in the example below, I would need the rows in bold highlighted:

 

Desk          Date

1                30 January

2                30 January

2                30 January

2                31 January 

3                30 January

 

Any help is appreciated. Thanks!

    Let's say the desk numbers are in A2 and down, and the dates in D2 and down.

    Select the rows that you want to format from row 2 down.

    The active cell should be in row 2.

    On the Home tab of the ribbon, click Conditional Formatting > New Rule...
    Select 'Use a formula to determine which cells to format'.
    Enter the formula

    =COUNTIFS($A$2:$A$10000, $A2, $D$2:$D$10000, $D2)>1

    Click Format...
    Activate the Fill tab.
    Select a highlight color.
    Click OK, then click OK again.

    =COUNTIFS($B$2:$B$10,$B2,$C$2:$C$10,$C2)>1

    You can apply this rule for conditional formatting of the sample data.

     

    =$B$2:$C$10

    This is the range the format applies to in the example.
