One of my friend contacted me about a solution he needs for his ongoing project. They are doing email migration of a company having Zimbra mailboxes to Exchange Server. Now for exported mailboxes saved as .tgz file to transfer them to Outlook, they are using a migration utility from SoftSpire named as "Zimbra Converter". But they also do have few users who was using ZCO and having messages saved in .zdb file. Now this .zdb file is not supported by tool.
Can anybody has experience in converting this .zdb file to Exchange Server.
