How to create the outlet border only while using raster data in ArcMap? I am already using raster to vector converting format but it did not help.
Can you tell me or explain about other way?

It looks like your image has NoData values around the edges. I would try reclassifying the image to a binary raster (1 = Data, 0 = No Data), and then trying raster to vector.
The GIS SE question Getting boundary of raster image as polygon in ArcGIS Desktop? asked about getting the boundaries of the entire image (NoData included), but it still looks to have some useful suggestions in the answers.
