Maybe its best to copy the emails to another sheet. make them unique, add a unique id manually to each email, then use vlookup to get the unique ids from sheet2 to sheet1?
User 13/09/2017 - 08:29
Thats one way i think i can resolve it, just though there might be an easy formula to this
Excelchat Expert 13/09/2017 - 08:29
