I have configured POP3 access to exchange 2007 mailbox on Sony Ericsson P1i (standard messaging application) and the strange think is, that when the message is deleted from P1i it is also deleted from user mailbox on exchange - after using send/receive option on P1i.
It happens on 3 different devices and 2 different exchange servers.
User does not want that this happens. Any suggestions how can I prevent this?
It has something to do with POP3 V3 protocol?
Perfect solution it would be, that user receives only new (unread) messages on mobile device and whatever he does with that messages, they still remains unread and present on exchange server until he/she connects and reads the message using outlook or owa.
Thank you for your help.
