    Hi @Dicha Ding

    As this setting is within the mailbox, there is no easy method for users to delete it.

    Please contact your Exchange admin and run the following cmdlet in Exchange Management Shell to remove this cache:

    Get-MailboxUserConfiguration -Mailbox <email address> -Identity Configuration\* | Remove-MailboxUserConfiguration -Mailbox <email address>

    Another method is to use MFCMAPI to login the mailbox and delete this entry:
