We are tracking this problem for more than 6 months. Our environment is Exchange Server 2013 CU3, client Outlook 2010 -32Bits- Pt-BR (Office 2010 with KB2910899 update applied), ESET Endpoint Protection v.5.0.2237 and Windows 7 Pro - 64Bits - PT-Br. Accounts are Microsoft Exchange by default and shared accounts are automapped. These tests were performed with ESET´s Outlook Integration enabled. The problem shows up in shared accounts or regular accounts with delegated Full Control Access (the same concept as shared accounts). We are certain that: 1) If every client Outlook has cached mode disabled, 100% messages arriving in the shared account´s Inbox will be changed to DRAFT; 2) There´s a side effect of ESET antispam Engine in Integration mode: Spam messages to shared accounts, moved by ESET antispam or Outlook filters to Junk Mail folder are replicated to Conflicts folder of every user in the shared account group. So users of shared accounts, that receives a lot of Spam, have also problems with their individual quota. 3) If we turn off Eset´s Outlook Integratin there will be no more Draft or replicated Conflict messages. This is a sample of a Sincronyzation Error generated by a "Test 1" message replicated to Conflicts, note the action of ESET Scanner,Antispam and MessageFlag over the message.

We asked regional dealer and they assured compatibility for IMAP and POP3 accounts. No answer about the situation above. What will be the impact over the network if ESET Integration is disabled?
