As of today, V3 of OnedriveMapper is in testing. It features an auto-updater and does native (no internet explorer) authentication.
The auto updater only works for OnedriveMapper Cloud beta testers, after beta OnedriveMapper Cloud will probably be a service where you can manage / control all OnedriveMapper settings as configurations for your organisation(s) centrally. OnedriveMapper Cloud comes as both a ps1 and msi version.
If you’d like to try OnedriveMapper Cloud, contact me.
Where can I find the V3 beta so I can help with the testing?
