A couple quirks: this might add a couple folders to your AKO account, you may end up with different 'trash' and 'sent' folders, perhaps even 'drafts.' This is the reality of using IMAP. Watch those extra folders, b/c when my Droid Pro 'deletes' an email, it moves it to a folder in my AKO called "Trash"...but that's not THE trash can, so the email isn't really deleted. I have to use the web browser once every few weeks and clear out those emails so they don't clog up my account quota. If step 2 doesn't work, you can try this to install your certificates: Launch "Files" app and navigate to the folder where you dropped your certificates onto the SD card. From there, open up the folder and you should see a list of your certificates. Long press on the first one, and in the menu that comes up, tap "Open." This will bring up an info pane, tap on the button that says "Install Certificate." Repeat that for the other certificates and you should be good to go. Hope this helps.
