Merhaba, son yıllarda mail kullanım oranı günlük yaşantımız için ne kadar önemli olduğunu hepimiz biliyoruz, kuruluşlar da Mail Server Adminleri’ne gelen en çok istek “Mailbox alanımı %10 artırır mısın?” oluyor. Tabi ortamınıza göre “Unlimited” mailbox kullanabilirsiniz ama kaynak kullanımı nı kontrol edebilmek için bazı limitlendirmeler yapmanız önerilmektedir.
Örnek; Sizden mailbox için IssueWarningQuota, ProhibitSendQuota ve ProhibitSendReceiveQuota limitleri için %10 artış talep ettiler. Bu durum da sizin her mailbox için ($currentquota + %10) hesaplamanız gerekiyor.
Yeni değeri kullanıcıya atamak için ECP üzerinde gezinmeniz yada uzun bir PowerShell komutu yazmanız gerekiyor. Bu istek bir den fazla kullanıcı için istenildiyse bu işlem çok fazla zaman alabiliyor.
Bunun için ilk yapılandırma ayarları, ortamın çalışma şeklini tasarlamak çok önemli, yüksek mailbox kullanan kullanıcılar için IssueWarningQuota, ProhibitSendQuota ve ProhibitSendReceiveQuota limitleri yüksek bir database oluşturabilirsiniz ve mailboxları bu database altında oluşturabilirsiniz. Database tarafında limit oluşturmayıp mailbox limitleri ile ortamı çalıştırıyorsanız aşağıda paylaşmış olduğum PowerShell scripti bu tip işlerinizi kolaylaştıracaktır. (İlgili Scripti EMS üzerinde çalıştırınız.)
Yazının alt tarafında paylaşmış olduğum Script ile tüm mailboxları database üzerinde yapmış olduğun default değerleri uygulatabilirsiniz yada belirtmiş olduğunuz mailboxlara % belirterek artış yapabilirsiniz.
Aşağıda belirtmiş olduğum şekilde çalıştırdığınız da “cengiz.yilmaz” mailboxına database üzerinde ki default değerleri uygulatabilirsiniz.
[PS] C:\Scripts>.\Set-MailboxQuota.ps1 -Mailbox Cengiz.yilmaz -UseDatabaseDefaults ---------------------------------------- Mailbox: Cengiz Yılmaz ---------------------------------------- Uses Database Defaults: False Warning Quota: 1.88 GB (2,019,086,336 bytes) Prohibit Send Quota: 1.98 GB (2,126,010,368 bytes) Prohibit Send/Receive Quota: 2.277 GB (2,444,702,720 bytes) Alannah Shaw has been configured to use database quota defaults.
Aşağıda belirtmiş olduğum şekilde çalıştırdığınız da “cengiz.yilmaz” mailboxının limitlerini %10 artıracaktır.
[PS] C:\Scripts>.\Set-MailboxQuota.ps1 -Mailbox cengiz.yilmaz -IncreaseByPercentage 10 ---------------------------------------- Mailbox: Cengiz Yılmaz ---------------------------------------- Uses Database Defaults: True Warning Quota: 1.899 GB (2,039,480,320 bytes) Prohibit Send Quota: 2 GB (2,147,483,648 bytes) Prohibit Send/Receive Quota: 2.3 GB (2,469,396,480 bytes) Calculating new quotas Current warning quota: 1991680 KB New warning quota: 2190848 KB Current send quota: 2097152 KB New send quota: 2306867.2 KB Current send/rec quota: 2411520 KB New send/rec quota: 2652672 KB Setting new quotas Quotas increased by 10 percent
Aşağıda ki komut DB001’deki tüm mailbox ları database üzerinde yapılandırılan varsayılan kota değeri ile eşitleyecektir.

.SYNOPSIS
Set-MailboxQuota.ps1 - Configure mailbox quotas for Exchange mailboxes
.DESCRIPTION
This PowerShell script allows you to quickly set mailbox quota values for
one or more Exchange mailboxes. You can use this script to set the mailboxes
to use the database quota defaults, increase by a specified percentage, or
decrease by a specified percentage.
.OUTPUTS
Results are output to console.
.PARAMETER Mailbox
The name of the mailbox you want to modify.
.PARAMETER UseDatabaseDefaults
This switch will set the specified mailboxes to use the default quotas
configured on the mailbox database on which they are hosted.
.PARAMETER IncreaseByPercentage
This parameter allows you to specify the percentage by which existing
quota values on a mailbox should be increased. If the mailbox is currently
using the default database quota levels the increase will be based off
those values.
If any of the three quota settings are set to "Unlimited" then this
parameter will not make any changes to the mailbox.
.PARAMETER DecreaseByPercentage
This parameter allows you to specify the percentage by which existing
quota values on a mailbox should be decreased. If the mailbox is currently
using the default database quota levels the increase will be based off
those values.
If any of the three quota settings are set to "Unlimited" then this
parameter will not make any changes to the mailbox.
.EXAMPLE
.\Set-MailboxQuota.ps1 -Mailbox Adam.Wally -UseDatabaseDefaults
The mailbox user Adam.Wally will be configured to use the quota
values configured on the mailbox database on which they are hosted.
.EXAMPLE
.\Set-MailboxQuota.ps1 -Mailbox Adam.Wally -IncreaseByPercentage 5
The mailbox user Adam.Wally will have their mailbox quota values
increased by 5 percent.
.EXAMPLE
Get-Mailbox -Database DB04 | .\Set-MailboxQuota.ps1 -UseDatabaseDefaults
All mailboxes hosted on database DB04 will be configured to use the
default database quota values.
