I am using the Mailbox Storage Information
report template and I would like to filter all mailboxes whose 'Issue warning' quota is not defined.
Unfortunately, I do not find any operator called Undefined
in the drop-down list.
Please set your filter as follows:
Issue warning (KB) > 1,000,000,000
(or any other very high value).
You can also use this method to retrieve mailboxes whose 'Prohibit send', 'Prohibit receive' quotas or message size limits are undefined in Exchange using the appropriate filters.
