I don't know if this makes a difference, but the "Scheduler" user (creator)
opens the five calendars automatically, because I set it up their profile;
Advanced Settings Open Additional Mailboxes. Cached Exchange Mode is ON.

It would have been nice to have included the information about other users
folders (calendars) in the first post rather than making someone (me) do
rework

Let me go try to reproduce it now with the additional information.

After furious head scratching, Support7556 asked:

| The Users are Opening/Using "Other's Calendar".
| There are five Calendars that they open, however two are only used
| weekly. The five Calendar's give everyone view(reviewer) rights.
| The Scheduler has Owner rights.
| Normal Searches (Finds) values are firstname and/or lastname which
| were created in Subject field.
| Advance Finds with Subject equals firstname and/or lastname.
| Sometimes additional criteria "Start" On or after Date.
| Usually only one person creates or edits appointments and many
| search/view Calendars.
|
| Could it be the number of appointments (items) in the Calendar?
| Or the number per day?
| The three busier Calendars have 6,000 to 14,000 appointments.
| They like keeping at least three months in the past.
