Get-MailboxDatabase | fl Identity,JournalRecipient
Get-MailboxDatabase | select name, JournalRecipient

Set-MailboxDatabase "Sales Database" -JournalRecipient "Sales Database Journal Mailbox"

Get-MailboxDatabase | fl Name,EdbFilePath,LogFolderPath

Get-ExchangeServer | Format-List Name, Edition, AdminDisplayVersion

1. 檢查DB是否開啟循環記錄，未開啟交易紀錄不會刪除需卸載再裝載才會生效

Get-MailboxDatabase | select name, circularloggingenabled | sort circularloggingenabled -desc | ft -AutoSize

2. 新增DB，將使用者移到新DB

Get-Mailbox -Database "YD-DB02" -ResultSize Unlimited | New-MoveRequest -TargetDatabase "YD-DB03"

Get-MoveRequestStatistics -MoveRequestQueue "MBXDB02"

Get-MoveRequest -MoveStatus Completed | Remove-MoveRequest

列出DB Size, Free Space, User Count

Get-MailboxDatabase -Status | select Name,@{Label="Free Space";Expression={$_.AvailableNewMailboxSpace.ToGB()}},@{Label="Size";Expression={$_.DatabaseSize.ToGB()}},@{Name="NumberofUsers";Expression={(Get-Mailbox -resultsize unlimited -Database $_.name).Count}} | ft -auto

Get-MailboxDatabase|FL name,*public*

get-exchangeserver

Export-Csv d:\temp\11.csv -NoTypeInformation -Encoding UTF8

檢查DB空白區

Get-MailboxDatabase -status | select Name,DatabaseSize,AvailableNewMailboxSpace

想要在多個資料庫和伺服器輕易套用已刪除郵件的保留限制嗎？ 試試下列命令來設定指定的伺服器上所有資料庫的已刪除郵件保留設定
：

 Get-MailboxDatabase -Server  | Set-MailboxDatabase -DeletedItemRetention 45.00:00:00

您也可以將相同的已刪除郵件保留限制或信箱保留限制套用於組織內的所有伺服器：

 Get-MailboxDatabase | Set-MailboxDatabase -DeletedItemRetention 45.00:00:00 -MailboxRetention 120.00:00:00

Cisco switch cpu high

源起：

輸入sh process cpu sorted 發現是dhcpd作怪

處理方法：

新增一個acl如下

access-list 111 permit udp any any eq bootpc log-input
access-list 111 permit udp any any eq bootps log-input
access-list 111 permit ip any any

然後在有ip helper-address的介面上加上ip accesss-group 111 in

從log查到異常大量dhcp封包來源：

%SEC-6-IPACCESSLOGP: list 111 permitted udp 172.18.24.7(68) (Vlan150 0025.112b.c20c) -> 255.255.255.255(67), 1 packet
%SEC-6-IPACCESSLOGP: list 111 permitted udp 172.18.28.3(68) (Vlan190 382c.4a77.f1b2) -> 255.255.255.255(67), 1 packet
%SEC-6-IPACCESSLOGP: list 111 permitted udp 0.0.0.0(68) (Vlan230 60a4.4ce7.d541) -> 255.255.255.255(67), 38773 packets
%SEC-6-IPACCESSLOGP: list 111 permitted udp 172.18.29.7(68) (Vlan200 14dd.a94f.7122) -> 255.255.255.255(67), 1 packet
