Newly saved items in Outlook Calendar are disappearing

[Guest]

This week I have tried to save items to my calendar and they keep
disappearing. I can save items to our Program Director and they stay in his
calendar but when I try to save to mine within 3 minutes they are gone.

Our techs are scratching their heads on this one.

this usually happens when outlook is using a pst as the default message
store.
