We are running the final release build 104. When we delete a message
from our device, it deletes it from the mailbox and properly places it
in the trash. However, the next day it shows back up on the device even
tho it is still in the trash.

We only have 2 devices right now, one is Windows Mobile and one is Droid
and it happens from both devices.

We do have retention turned on so items can't be emptied from trash
until after a backup, is it possible this causing this? And if so, will
it be resolved with the next release?

It is going to be difficult for me to allow all of our employees access
if they can't delete messages from the phone.
