There are three storage limits, warning, prohibit send, and prohibit send and receive. If you chose to enter only one, the other two will be "Unlimited". If the UseDatabaseQuotaDefaults property is set to True, then the user's settings for ProhibitSendQuota, ProhibitSendReceiveQuota and IssueWarningQuota are ignored regardless of what they're set to.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

What is your default mailbox limits set to please provide values: Issue quota prohibit send prohibit send\receive If your prohibit send quota is 50% greater then or set to unlimited than the issue quota users will not get a quota warning and thus will show "unlimited" for issuewarningquota. Users do not receive quota warning messages after applying SP1 for Exchange 2010 http://support.microsoft.com/kb/2480474James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

James, We were using nag messages without prohibiting send and now, since SP1, that is not possible. Are you aware of any work-arounds or 3rd party tools that can provide mailbox size nag messages without needing the prohibit send flag set? Thanks. Hunter

Set-Mailbox -IssueWarningQuota setting defines when to send what you call nag messages.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
