I have one user (and only one out of 60) that has this same problem on an ongoing basis. By ongoing I mean it happens at least 2 or 3 times a week. In fact it is worth talking about if we can go 2 days without dealing with it. I have the routine down:
1. Check Outlook's About box for disabled sharing add-in and re-enable (usually but not always necessary).
2. Check registry for sharing mode and set it to 3 if necessary (usually not needed).
3. Delete the darn outcmd.dat file.
This last step 3 is always needed. Does anybody have any ideas what is going on here? This is (of course) a top-brass email user's problem and she's ready to torch the IT dept because of it.
It looks to me like an Outlook problem that is manifesting itself as a Zimbra error. It looks to her like Zimbra is the trouble. Will Zimbra 5's check for the sharing add-in solve this? It would seem to require a deletion of outcmd.dat as well to be effective.
Any thoughts on this would be appreciated.
Best wishes to all during the holidays.
