I have multiple one drive account . Earlier in windows phone 8 I was able to do a signout and login into another account , but now I am not finding that option . How can I do it in windows phone 8.1 ? I download preview version of windows 8.1
The latest OneDrive app for Windows phone 8.1 allows using multiple accounts.
As Drowin mentioned, there is no way to logout of OneDrive app starting Windows Phone 8.1. Read more about here.
As a workaround, you can share all your folders on your other account with the account that is associated with WP. With that you should be able to view all your files here.
Hope this helps.
