I’ve got a lot of items selected but how can I count them automatically? Windows shows in the Status Bar the amount of selected items but Outlook doesn’t.
Outlook has no way of telling you that but indeed just continues to display the total amount of items in the folder.
While whipping up some code to display the amount of selected items in a message box is not that hard to do, there is actually a native alert feature we can abuse here which will give the same results. When you select more than 4 items and press ENTER Outlook will display an alert telling you the following;
"Opening a lot of items could take some time. Are you sure you want to open these <number> items?"
Of course we will click "No" but at least we now know how many items we had selected.
