Exchange 2007 mailbox quota
Can Exchange 2007 mailbox quotas be applied to a security group members?

YES. If a mailbox is owned by a security group (that is, if it is a shared mailbox), quota messages are sent to the security group, that is the speciality.Regards from www.windowsadmin.info

Hi Naraka, Yes, you can set mailbox quotas for every security group member. In Exchange 2007, the storage quotas can be configured on mailbox level and database level. If you want to configure quotas for mailbox, please refer to this document: How to Configure Storage Quotas for a Mailbox http://technet.microsoft.com/en-us/library/aa998353(EXCHG.80).aspx By default all the mailboxes are using the database setting, and administrator are allowed to specify custom quota limits for specific mailboxes. you can know more detail from this document: How to Configure Storage Quotas for a Mailbox Database http://technet.microsoft.com/en-us/library/bb201753(EXCHG.80).aspx If you have any other requirements, please explain your problem in detail.

Thanks for the great responses. Let me clarify though - I have for instant a security group called 'Tier 1 Mailboxes' which I want to assign a mailbox policy that limits total mailbox size to 1GB. I then want to populate that security group with he respective user accounts that should have the 1GB limit set instead of defining at a database level.

Hi Naraka, From your description, I understand that you want to set mailbox Quotas (1 GB limit) for all users in that security group. Please correct me if I misunderstand. For this issue, you can achieve the goal by this way: Create a .csv file to include all the users in the security group, for example c:\ group.csv. the format can be: Name User1 User2 …. Then run this cmdlet: Import-Csv c:\group.csv | foreach {Set-Mailbox -Identity $_.Name -IssueWarningQuota 1073741824 -ProhibitSendQuota 1073741824 -ProhibitSendReceiveQuota 1073741824 -UseDatabaseQuotaDefaults $false} After that all the users in security group the mailbox limit are set to 1GB (You can use this command to check “get-mailbox –id user@domain.com |fl *quota*”).

Hi Naraka, From your description, I understand that you want to set mailbox Quotas (1 GB limit) for all users in that security group. Please correct me if I misunderstand. As far as I know, for a security group, there is no way to set mailbox quota, we need to assign the policy to all individual mailboxes in that group: Create a .csv file to include all the users in the security group, for example c:\ group.csv. the format can be: Name User1 User2 …. Then run this cmdlet: Import-Csv c:\group.csv | foreach {Set-Mailbox -Identity $_.Name -IssueWarningQuota 1073741824 -ProhibitSendQuota 1073741824 -ProhibitSendReceiveQuota 1073741824 -UseDatabaseQuotaDefaults $false} After that all the users in security group the mailbox limit are set to 1GB (You can use this command to check “get-mailbox –id user@domain.com |fl *quota*”).

Hi Narka, If your group( Tier 1 Mailboxes) is Mail-Enabled Universal Security Group, you also can run this command to achieve the goal: get-distributiongroupmember -identity "Tier1Mailboxes" | foreach {Set-Mailbox -Identity $_.Name -IssueWarningQuota 1073741824 -ProhibitSendQuota 1073741824 -ProhibitSendReceiveQuota 1073741824 -UseDatabaseQuotaDefaults $false} Thanks, Evan Liu TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

I like the suggestion from Evan and it seems to work. I however did not notice any difference although I can see that the new quota setting is applied to the test account which has a 2GB mailbox and has a 1GB limit. Is there something else I need to run before I see the administrative message in the test account mailbox (size warning)?

Hi Naraka, How long did you wait? As far as I know it will take up to two hours for the new limits to apply, this is expected behavior. Maybe you can restart Microsoft Exchange Information store service to accelerate update.

As said by Evan, storage limit's are not instant. An IS service restart will cause the limits to be re-read instantly.
