I recently moved some of the subfolders around in my exchange account at work (from subfolders of the inbox to a folder in the main mailbox), but then I decided I prefered it better the other way round. My Pre updated to the new folder locations, but when I changed them back they stayed put and no longer synced.
Not a problem I thought, I'll remove the account and add it again and all the folders will be back in the correct location. Wrong!
After selecting remove account, the button turned to removing account with the spinning icon and sat there. And continued to sit there. Eventually I got fed up of this, went out of the email setup and did something else for a while. I went back in later, and the account was still there but if I try to expand the account nothing happens.
I now seem to be stuck with an account which won't delete, won't reinstall and won't sync. Has anyone else come across this? Am I going to have to resort to a partial erase?
