Exchange 2013 - Quota notifications problem

Question

Hello,
First of all I want to express mild disappointment with the way quota notification alerts are documented on Technet for Exchange 2013. The only reference I could find is that QuotaNotificationSchedule parameter of the Set-MailboxDatabase cmdlet no longer
does anything: "This parameter has been deprecated in Exchange 2013 and it no longer does anything.".
The only other reference I could find is this forum post:
http://social.technet.microsoft.com/Forums/exchange/en-US/f30bb2ca-91ab-4e69-a8b6-720e6a8a5b83/exchange-2013-quota-notification-message-not-sent-during-schedule?forum=exchangesvrgeneral
where it says: "Quota messages are generated once the user log in to mailbox in exchange 2013."
However, Microsoft Press published a book in 2013 "Inside Out: Microsoft Exchange Server 2013: Mailbox and High Availability" where QuotaNotificationSchedule parameter is being referenced as a working parameter which controls when Quota notification
are being sent.
My experience says that the forum post is correct.
Now onto the problem.
While our customer was still on Exchange 2010 they were the victims of this issue:
http://support.microsoft.com/kb/2480474/en-us which could easily be fixed with
CheckWarningQuota registry key.
Now we have migrated those mailboxes to Exchange 2013 and again, users are not receiving quota notification e-mails. Only a few users receive quota notifications e-mails and those are users that got their mailbox created on the new Exchange 2013 system.
Migrated users do not receive notifications. We have tried CheckWarningQuota on Exchange 2013 but it does nothing. Our theory is that mailbox flag introduced in Exchange 2010 SP1 is migrated with the mailboxes to Exchange 2013 and is the
reason why we are not receiving quota notifications again.
I appreciate thoughts and comments.

CU8 addresses this issue, however, only for mailboxes not yet moved to 2013: https://support.microsoft.com/en-us/kb/303695
Mailboxes already moved will have to be manually fixed. The issue is they are missing their lcid (location ID). For whatever reason, the attribute does not make it across from 2010 to 2013. However, if you move the mailbox again to another 2013 database,
it fills in the lcid automatically. That is one workaround, but not necessarily a good one for people who have migrated a ton of their users already. So what do you do?
In the KB article, it shows you how to identify the users who are missing their LCID by doing the following in the exchange management shell:
#first load in the ManagedStoreDiagnosticFunctions, you will need this for the get-storequery cmdlet to work.
. .\'C:\Program Files\Microsoft\Exchange Server\V15\Scripts\ManagedStoreDiagnosticFunctions.ps1'
#then generate the list of all mailboxes with an LCID of 0.
$mbxs = get-mailbox –resultsize unlimited| ? {$_.exchangeversion.exchangebuild.major -ge 15}
$mbxsq = $mbxs | %{Get-StoreQuery -Database $_.database -query "select * from Mailbox where Mailboxguid = '$($_.ExchangeGuid)'"}
$mbxsq | ? {$_.lcid -eq 0} |fl displayname, mailboxguid, lcid
You can modify the script to dump the list to a text file if you need to.
Now, to address this, I simply populated the lcid for all my mailboxes. All of mine were en-US or lcid 1033, so it was easy to set them all at once. I just grabbed all Exchange 2013 mailboxes and applied the language (en-US) and DateFormat (MM/dd/yyyy) to
them (replace DOMAIN with your domain name) which in turn sets the lcid to 1033:
$mailboxes = get-mailbox -resultsize unlimited| ? {$_.exchangeversion.exchangebuild.major -ge 15}
($mailboxes).SamAccountName| %{set-MailboxRegionalConfiguration "DOMAIN\$_" -Language en-us -DateFormat MM/dd/yyyy} | FT -a
Incidentally, if you have already migrated all of your 2010 mailboxes, and you are on at least Exchange 2013 CU6, that script will resolve the issue whether you apply CU8 or not. CU8 fixes it for any other mailboxes that have not yet been migrated to 2013.
Hopefully this help you out.
