Okay, after further searching I found this: http://blogs.technet.com/b/exchange/archive/2006/09/20/3394913.aspx
which contains this: If mailbox database settings are used as defaults, the values for the following would take effect: Exchange Management Shell Active Directory IssueWarningQuota unlimited mDBStorageQuota Not Set ProhibitSendQuota unlimited mDBOverQuotaLimit Not Set ProhibitSendReceiveQuota unlimited mDBOverHardQuotaLimit Not Set UseDatabaseQuotaDefaults TRUE mDBUseDefaults TRUE * In this case, "unlimited" does not mean the mailbox has unlimited size. Instead you would need to reference the mailbox store storage limits to see what the limits are currently set to. Sheesh... How the heck is that logical? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Maglinger, Paul Sent: Tuesday, February 11, 2014 6:02 PM To: '[email protected]' Subject: [Exchange] RE: Quota report showing unlimited on mailboxes set for default limits And propagate is the wrong term. But if that option is checked to use the defaults, and I change the defaults, then the mailboxes in that database should then start using the new values after replication. Right? -----Original Message----- From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Maglinger, Paul Sent: Tuesday, February 11, 2014 5:56 PM To: '[email protected]' Subject: [Exchange] RE: Quota report showing unlimited on mailboxes set for default limits Michael, I don't mean to be dense here. Are you saying that in the User's Mailbox Properties, if I have " Use mailbox database defaults" checked, it's not going to use the settings I have specified in the mailbox database properties limits that the mailbox is contained in? -----Original Message----- From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Michael B.

It's a hierarchy. I wrote an entire section on this in my Exchange 2003 book.

So the value of the mailbox database limits should propagate to the user's mailbox, right? That doesn't seem to be happening. -Paul -----Original Message----- From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Michael B. Smith Sent: Tuesday, February 11, 2014 5:30 PM To: [email protected]<mailto:[email protected]> Subject: [Exchange] RE: Quota report showing unlimited on mailboxes set for default limits They are database defaults. They don't propagate. If the users have no value (i.e., unlimited) then if "usedatabasedefaults" is set on the user object, then the database defaults are checked. Otherwise the user is unlimited. Works as intended. Been this way since Exchange 4.0. -----Original Message----- From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Maglinger, Paul Sent: Tuesday, February 11, 2014 6:12 PM To: New Exchange List ([email protected]<mailto:[email protected]>) Subject: [Exchange] Quota report showing unlimited on mailboxes set for default limits Exchange 2010, SP2, UR6 On each of my databases I have set default limits of say 120, 140, and 160MB. When I run the following script: Get-Mailbox -ResultSize Unlimited | Select-Object DisplayName, IssueWarningQuota, ProhibitSendQuota, @{label="TotalItemSize(MB)";expression={(Get-MailboxStatistics $_).TotalItemSize.Value.ToMB()}}, @{label="ItemCount";expression={(Get-MailboxStatistics $_).ItemCount}}, Database | Export-Csv "C:\Scripts\UserMailboxSizes.csv" -NoTypeInformation all the users that have Use the Mailbox Database Defaults show up as Unlimited. Users that I have set limits individually on show up correctly. This is not a replication issue. They have been set up like this for days. It is only because I ran the script above that this came to light. Event logs look good. Databases on a 3-node DAG - everything is healthy. Can someone point me to what would keep the mailbox database defaults from propagating to the mailboxes? -Paul
