I have an Exchange 2003 server with Outlook 2007 clients, and every once in a while a user will create a meeting request, send out invitations, but then not be able to send meeting updates out. They are also missing the "attendees" grouping in the menu meeting window as well. Instead, they have a "respond" grouping with the options to accept/decline/propose. They shouldn't be getting this, because as creators of the meeting request, they do not have to accept/decline the meeting. Even after we choose to accept, they still don't have the ability to send updates or manage attendees. Though they are still listed as the meeting organizer, the ability to manage the meeting and the attendees appears to be taken from them.

Hi, First, I would like to confirm whether the user create the problematic Meeting Request via Blackberry? Does the issue occur when logging on the Mailbox via OWA or Outlook Online Mode on PC? If the user is logging on the Mailbox via Blackberry, please perform the following steps. 1) Go to Session->Logon and Display Store Table 2) Select your profile (Ensure Outlook profile is configured in online mode) 3) Select Mailbox 4) Expand "Root Container" 5) Expand "Top of Information Store" 6) Double click "Calendar" and select the problematic meeting request. 7) In the bottom pane check for 8217 under ‘Named Prop Name’ 8) Double click and Check if the value is 3. Change it to 1 and check the result. Note: ===== Please take Backup of the Calendar Folder by exporting the Meetings to a PST. Steps to do that are below. 1) Click on "File", "Import and Export". 2) Select "Export to a File". 3) Click "Next" and select "Personal Folder File" 4) Select the 'Calendar' Folder from the list and click 'Next'. 5) Save the PST file to a location on the local drive. 6) Click Finish To Import the data back from the PST follow the same steps but instead of "Export to a File" Select Import from another program or file.
