I've got some troubles with the newest ZCOs. On some of my users, once I install 6.0.6 or 6.0.7 ZCO, they get continual Outlook crashes. The error report always has lslib32.dll as the troublemaker. If I put them back on 6.0.1 or 5.0.18 ZCO, they seem to be stable. Users are on Outlook 2003, SP3 with all available Microsoft updates. I've tried repairing ZCO, no luck. I've tried removing and reinstalling, no luck. If I delete their Outlook profile and recreate, it might stay stable for a day or so.
