Hi All, We have been using Parallels plesk infront of the Microsoft Exchange Server 2007. We decided to use Office 365 and IMAP method is using for migration. When we' re trying to migration user to Office 365 we face below error. In my lab scenari there is same Exchange 2007 Server but there is no any issue like that. I think some Parallels behavior makes me deny, could you help me about that please? 3/19/2015 9:49:26 AM [DB3PR01MB377] Missing Item () Subject:"", Folder:"" 3/19/2015 9:49:26 AM [DB3PR01MB377] Missing Item () Subject:"", Folder:"" 3/19/2015 9:49:26 AM [DB3PR01MB377] Missing Item () Subject:"", Folder:"" 3/19/2015 9:49:26 AM [DB3PR01MB377] Missing Item () Subject:"", Folder:"" 3/19/2015 9:49:26 AM [DB3PR01MB377] Missing Item () Subject:"", Folder:"" 3/19/2015 9:49:26 AM [DB3PR01MB377] Missing Item () Subject:"", Folder:""
