I have finally moved over to my ZCS server for e-mail and want to retire my Exchange server. Mail is flowing into and out of it just fine - the problem I'm having is importing all my old mail from Exchange.
I've found the new and depreciated tools in Zimbra and tried them all. The 'Zimbra Migration' utility works 'ok' for importing from PST, but the format of the messages that it imports is totally messed up - basically, HTML messages seem to lose everything but the text that they had in them. If I try using it to import direct from the Exchange server, every single message has a simple text string indicating that it has no content.
The old PST import tool fails pretty much right away due to 'too many errors'
I've tried using PSTs from Outlook 2010 and Outlook 2013 (2013 was first and I thought maybe it was something with the 2013 format).
I also tried connecting Outlook up to the Zimbra server via IMAP and copying messages in that way - that messed them up even more.
Is there some way that I'm missing to import the messages from PSTs that will preserve the formatting? Maybe a 'best' version of Outlook to use to export to PST?
