Calendar processing for users changing???

[Sambooka]

Hi

I have had 3 users in the past few weeks call up saying that emails are going directly into their deleted items.

when I run get-calendarprocessing I see they are set -automateprocessing autoaccept

I have to set -automateprocessing autoupdate

I cant figure out why the settings are changing tho.. any ideas?

I ran a query against the other mailboxes and currently the only people who have this setting are either departed users or workrooms with shared calendars.
