Using classic Outlook for Windows in business environments
Hi, I'm Karl and will be happy to help you today.
The best way to do that would be to sort the folder by date and then highlight the first and last message in the date sequence you want to delete.
This is done by
#1 - Select the applicable folder
Sort the folder by date - there are 2 ways to do that
Option #1
#2 - Click on the filter icon (down arrow - top right of the items list)
#3 - Select <Date>
Option #2
#4 - Click on the <View> ribbon tab
#5 - Click on <View Settings>
#6 - Click on <Sort>
#7 - Select the field(s) you want to sort on (i.e. <Received>)
When done
#8 - Single click on the first item you want to delete
#9 - Hold down the <Shift>key and click on the last item in the sequence you want to delete
#10 - Press <delete> to delete all the selected items
