Offline IMAP Sync Between 2 servers with an existing folder

[Blake Pfankuch]

I am using OfflineIMAP in a fairly unique situation.  I have the need to sync messages from a voicemail system that is restricted to using IMAP (internally) to a publically available mail system (Exchange) for a few users who "need" access to their voicemail without dialing in to retrieve them while on the road.  I have the config all set up and written, and my test accounts in place for this and I'm running into something that has been mentioned before on this list.  Going through the archive I did not see a solution, however discussion of this on November 20th 2011.  I have my config set to only sync Inbox on an IMAP server to INBOX on another IMAP server.  I care only about the messages within this folder and nothing else.

When I trigger offlineimap I get this result.

[offlineimap at OfflineIMAP ~]$ offlineimap
OfflineIMAP 6.5.2.1

Offlineimap --info shows the following

Any thoughts on a workaround for this for existing folders, or do I need to look to a translation as an alternative?  Would a translation allow me to convert Remote "Inbox" to Local "INBOX\Voicemail" easily?

Thanks for any insight!
