After using the WP10 Preview version for a couple of weeks, last night I had to use the Recovery Tool and revert back to 8.1.
Problems with WP10 started immediately, when I could not use my SD card with the OS. Every time I booted up I got this message: "SD card slot disabled. You can't use SD cards on your phone because of a server policy." We could never figure out what "server policy" the message referred to. I am on an Exchange account at work, we run Sophos Mobile Control. I do not run AirWatch (don't even know what that is). Mobile Control is set to allow the SD card, I never had a problem on any previous version of the OS. I see a discussion on I see a discussion here on the MS Community page, other folks having this same issue and they don't mention Mobile Control, so it may not even be an issue with that program.
Have spent a lot of time with our IT on this with no solution. So I had to store everything on my phone, and eventually after a couple of weeks my phone storage filled up yesterday and then corrupted/crashed all my email accounts so they couldn't sync. We uninstalled and reinstalled Mobile Control, and each of the email accounts several times with no luck. Not only could we not get the 830 to use the SD card, I couldn't get either of my 2 email accounts to sync, nor could I even get the Email Account settings app to load. After many hours, I reverted to WP 8.1 last night and got my SD card back. I would like to stay with WP 10 and get a 950 or 950XL, but will not do that without being able to use an SD card. So far no suggestions have worked.
