While preparing an new client laptop I came across the situation where exporting the favourites from Internet Explorer 11 on Windows 10 failed. Given I’d done this many times – the surprise was when “Some settings were not exported successfully” was displayed.
In addition the file that I had specified wasn’t empty as I might have expected – it wasn’t there at all!! After checking the location if was offering to save the file in (c:\tmp in this case) – I tried to create a file – only to find the user I was exporting as had no permissions in that folder which had been created specifically for a client application.
A quick change of location allowed the file to be exported ! Pity the message wasn’t a bit more forthcoming about the reason why “Some settings were not exported successfully” – would have saved client head-scratching.
