Its mainly because Office now defaults its save location to Onedrive. The only real benefit I get is the auto save every 3 seconds. Other than that, I always try and point it to local. However, at work we're migrating to sharepoint so eventually Onedrive save will always be encouraged.
Nice timing. Going on a cruise over all of Christmas and won't have Internet but taking my laptop with me. Could use this on some of the posts I've saved thst talk about useful powershell scripts or python stuff.
