I have had the $30 corporate email plan add on for years but then decided to ask if it was necessary. Verizon basically said it may not be necessary so I removed it. Now I know I can still connect to my Exchange server but it seems that push has been negatively affected. Can I assume I don't need the corporate plan because I am able to send and receive email and the push issue is just an anomaly? i mean, wouldn't it stop working altogether? Thanks!
