I have tried several times unsuccessfully to rid myself of these email messages on my outlook at work. The message i get is from blackberry.net and it reads that the information in the email is being used to update the server and should not be deleted. Verizon folks have had me reinstall the desktop software being careful NOT to select corporate email. On the third call in to verizon, the tech assist said my account was set up as a corporate email and then changed to regular email. we then reinstalled and rebooted everything. At first, everything seemed ok but after a few days, I started getting the same ETA messages from blackberry.net. though this time, I only get them on my outlook on my pc, not my device.
As well, i've noticed that once these messages appear, I do not get all emails on my device. Otherwords, some emails that appear in outlook do not arrive on my device.
