I imported my emails/calendars etc from exchange to zimbra. However if I select one of my old messages that I have imported and try to hit reply nothing happens. On opening the error console on Firefox I see the following error:

Error: addr.getAddress() has no properties
Source File: http://dhdhdh/zimbra/js/ZimbraMail_a...v=070518072157
Line: 24655


Any idea what might be wrong?

However reply on any other mails (i.e created on zimbra itself) is working fine,
