Using Outlook for Android for personal email and calendar management
I am not sure, sorry. Perhaps when you find it in store, try to Install Webview again, the new version may override the old one. The update on Webview seem to be ok with Outlook now.
Also I noticed that when you scroll down, you can see what email is Webview associated with, there may be several and you can change the default settings so you can change it.
Good luck!
