Corporate Sync causing SD card issues
So, this issue has been driving me mad for a couple of weeks now and Verizon can't figure out what's going on. I've spoken to tech support and taken the phone(s) in to several different VZ stores. All they would do is have a "new" phone sent to me (the phone actually wasn't new, but certified like new because i didn't notice my problem until after my 14 days were up... WHAT?). Anyway, I just figured out last night that the issue was specifically associated with my setting up my corporate email account. As soon as I set up my account using the Corporate Sync app, it would encrypt my SD card, meaning I can't see it (it's greyed out), format it, or (un)mount it. Thank you to all of you who have posted here. Now, I know I'm not the only one!
Here's how I "fixed" my problem... first of all, this will only work if your work does not require SSL. Anyhow, during setup, I uncheck SSL and then when the message pops up telling me about encryption, I simply hit the home key. This makes it seem as though you are not completing your setup, which is partly true. What you'll find is that your account is indeed set up and you can access it through your email tab. Also, if you go to your menu/settings/location & security/data encryption, you can turn encryption off. I don't know the downside of this, but it's worked for me so far.
The other option is downloading Touchdown, which is an easier alternative.
