Exchange Server yapısı ölçeklendikçe kota yönetimi kritik hale gelir.
“Mailbox kapasitesini %10 artırır mısın?” talebiyle sık sık karşılaşabilirsiniz.
Bazı kuruluşlar Exchange Server’da Unlimited kota verebilir; ancak çoğu zaman kaynakları dengelemek için sınır koymak mantıklıdır.
Özet: Bu makalede Exchange Server’daki (2019/2016) tüm posta kutularının IssueWarningQuota, ProhibitSendQuota ve ProhibitSendReceiveQuota değerlerini tek komutla %10 artırmayı öğreneceksiniz.
PowerShell scripti, kotaları dinamik olarak hesaplar ve ister tek bir kullanıcıya ister yüzlercesine otomatik uygular.
İçindekiler
Exchange Server’da Neden Kota Yönetimi Önemli?
- Depolama maliyetini düşürür.
- Sunucu performansını korur.
- Exchange Server Database boyut patlamalarının önüne geçer.
- Kullanıcı deneyimini iyileştirir (uyarı eşikleri sayesinde).
Kuruluşlarda yaygın talep: “Mailbox kapasitesini %10 artırabilir miyiz?”
ECP ile tek tek yapmak yorucu; PowerShell size zaman kazandırır.
- Exchange Server Subscription Edition RTM Yayınlandı
- Active Directory UPN Suffix Ekleme ve Kullanıcı UPN Değiştirme
Exchange Server’da Tek Bir Posta Kutusunun Kotasını %10 Artırma
.\Set-MailboxQuota.ps1 -Mailbox "cengiz.yilmaz" -IncreaseByPercentage 10Komut EMS’de (Exchange Management Shell) çalıştırılır.
Script, mevcut kotaları okur, matematiksel olarak %10 ekler ve ayarlar.
Exchange Server’da Tüm Mailbox Kotalarını Yüzde Olarak Artırma
Yukarıda bahsettiğim, Exchange Server’da kullanıcıların mailbox kotalarını yüzde olarak artırmak için kullanabileceğiniz PowerShell scriptini aşağıda bulabilirsiniz. Bu script, mail hesaplarının kotalarını belirli bir yüzde ile artırarak Exchange Server yöneticilerine zaman kazandırır ve işlemleri otomatize etmelerini sağlar.
Exchange Server’da Tek bir Posta Kutusunun kotasını %10 artırır.

.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.
