Are ALL your clients up-to-date on their software patches?
Are ALL your clients using the same version of Outlook?

I have a user that peridically will loose his calendar information viewed
by
others. He can view his calendar but others see no information when they
attempt to schedule meetings with him. I have verified all suggested
settings with no luck. The only thing that sometimes works is to change
any
setting on his active directory account. Will work for a while then
disappear again.
