Kindly refer my below solution
Hope this might help you
For recieved time/date sample syntax
" [ReceivedTime] >= ‘02/23/2022’ AND [ReceivedTime] <= ‘02/25/2022’ "
One more method by not use filter property
Use get outlook message activity
Drag a for each activity
So for each. Item in mail message
Put a if condition with statement below
Item.subject.contains(“Complete”)
Then do your desired step
Else. Skip
Thanks
