For Windows computers, Lansweeper scans the software that is listed in Add/Remove Programs (Programs & Features). Exchange should be detected if it is listed in Add/Remove Programs. I would recommend that you:
- Update to the latest Lansweeper release by following these instructions.
- Check what is listed in Add/Remove Programs on the server. If the software is not listed here for some reason, it will not automatically be detected and you will need to use file or registry scanning to detect it.
- Rescan the computer by hitting the Rescan Asset button on the asset page. Wait for the Last Seen (= last successful scan) date listed on the computer webpage to update.
