Environment: Single exchange 2003 box, running on server 2k3. latest service packs applied. all but latest round of patches applied.
Symptom: A single user cannot view any meeting invite via IMAP/OWA. Works fine in outlook, but its a users who primarily uses linux, so thats not an option. They get HTTP 500 responses for every calendar invite they have. Tried in Firefox/Chrome/IE (7 on xp). This isnt new, its just being reported for the first time.
Nobody else is reporting the issue.
Ive certainly seen this here and there with corrupt invites, but not every invite in a mailbox.
Edit 2 (more detail): Its actually just updates & cancellations the error is occurring on. Also, updates and cancellations do not appear when the user connects via IMAP.
