Return MAX result for specific criteria for multiple values

I would like to be able to return the latest dates (Column D) from a criteria that has multiple results . I need to do this for 8-9000 lines every day. I have tried doing this with Array formula, but it only give me the result from the cell that I dragged it from.

Has anyone got any idea's for a formula that I could put in Column E that would check all of the cells in column A against the row the formula it is in and then return the max value of the matching criteria.

Appreciate all the help and apologies for not making my request clearer
