Some of you may have seen this:
The title of the KB is “"Could not complete the operation. One or more parameter values are not valid" error message when an organizer updates a recurring meeting” and it concerns an issue where we find PR_SENT_REPRESENTING_NAME to be missing on various calendar entries, which in turn leads Outlook to complain when you try to update the meeting. We’re working on a fix for Outlook that should be out soon, but I’m still trying to track down why that property went missing in the first place. Here’s where I was hoping the community could help. I know several of you out there have encountered this problem. I need data from a mailbox where the issue has been seen. In particular, I need to get the Calendar Version Store and Calendar Logging that Exchange keeps. In that data I hope to find some clues as to where the property went.
What I want to get is the Calendar Logs for a user who has seen the problem, but I don’t want to get them the usual way, using Powershell. Instead, I want to get them directly using MFCMAPI. Here are the instructions:
You can do this on any user who has seen the problem, regardless of whether you have “fixed” the appointments by restoring the property via MFCMAPI. If you happen to know the subject of an appointment which was broken to help me focus my research, that would be helpful, but not essential.
If you can – great! I can offer my undying gratitude in return. Just contact me through this blog and I’ll arrange a secure means to transfer the logs to me. The data will be kept securely here while I analyze it, then will be deleted. I’ll keep you updated on anything I find in the data that may help us track this problem down.
Thanks in advance to anyone who can help us track this issue down.
