Scenario:  You want a script to set the Paging File Size to 32GB on multiple servers remotely.

Solution:  Run this script from a computer that has the ActiveDirectory Module for PowerShell installed.

#Query AD for your Servers
Import-Module ActiveDirectory
$strOU = "OU=Exchange2016,DC=XYZ,DC=COM"
$servers = get-adcomputer -searchbase $strOU -properties Name -Filter *|  where {$_.name -like "Ex16-*"} | Select -ExpandProperty Name

#Loop through all Exchange Servers and set the Custom Paging size to 32GB 
$servers | Sort Name | %{"Setting Page File Size on $_"; Invoke-Command -Computer $_ -ScriptBlock {
[int]$InitialSize = 32778
[int]$MaximumSize = 32778
$ComputerSystem = $null
$CurrentPageFile = $null
$modify = $false
$ComputerSystem = Get-WmiObject -Class Win32_ComputerSystem -EnableAllPrivileges
if ($ComputerSystem.AutomaticManagedPagefile) {$ComputerSystem.AutomaticManagedPagefile = $false; $ComputerSystem.Put()}
$CurrentPageFile = Get-WmiObject -Class Win32_PageFileSetting
if ($CurrentPageFile.InitialSize -ne $InitialSize) {$CurrentPageFile.InitialSize = $InitialSize;$modify = $true}
if ($CurrentPageFile.MaximumSize -ne $MaximumSize) {$CurrentPageFile.MaximumSize = $MaximumSize;$modify = $true}
if ($modify) { $CurrentPageFile.Put()}
}}

Scenario:  You want to query all Exchange recipients that do not have a email alias with the @XYZ.com domain.

Script: Use this command to export the recipients to a .csv.

get-recipient * -filter {emailaddresses -notlike ‘*@xyz.com’} -ResultSize unlimited | Export-csv C:tempxyz.csv

Scenario:  You want a logical way of exporting message information for all messages in a mailbox dumpster. In this scenario we are going to target the date of which items show  ‘deleted on’ in Outlook when in the ‘Recover Deleted Items’ folder.  The message property for this ‘Deleted On’ date is LastModifiedTime.

Script:  The following EWS script runs in 5 day increments as you are maxed out  when performing a filter/view against a dataset with EWS at a specific number.  The mailbox had a large number of recently deleted items. If you are able to, feel free to adjust the values for  $startdate.adddays(x) and $enddate.adddays(x) so you do not end up with 1000’s of files like me.

#Connect to Exchange Service
        Import-Module -Name "C:Program FilesMicrosoftExchange ServerV15BinMicrosoft.Exchange.WebServices.dll"
        $service = new-object Microsoft.Exchange.WebServices.Data.ExchangeService([Microsoft.Exchange.WebServices.Data.Exchangeversion]::exchange2013)
        $service.Url = new-object System.Uri("https://ex2013svc1/EWS/Exchange.asmx")
   
 #Pick the Mailbox
        $mailboxname = "baduser@domain.com"
 
#Bind to the RootFolder
        $folderid = new-object Microsoft.Exchange.WebServices.Data.FolderId([Microsoft.Exchange.WebServices.Data.WellKnownFolderName]::RecoverableItemsDeletions,$mailboxname) 
        $RecoverFolder = [Microsoft.Exchange.WebServices.Data.Folder]::Bind($service,$folderid)

#starter Variables
        [datetime]$StartDate  = "1/1/2005"
        [datetime]$EndDate = "1/5/2005 23:59"
        $result = @() 
        $temp = @()
        $Today = Get-date

#loop it
Do{
        #Define Loop Variables
        $file_startdate = ($startdate).tostring("MMddyyyy")
        $file_enddate = ($enddate).tostring("MMddyyyy")
        $file_Datestring = $file_Startdate +"_"+$file_Enddate
        "Searching $file_DateString"
        #Create Collection and Query upon your Filter
        $sfCollection = new-object Microsoft.Exchange.WebServices.Data.SearchFilter+SearchFilterCollection([Microsoft.Exchange.WebServices.Data.LogicalOperator]::And);
        $Sfgt = new-object Microsoft.Exchange.WebServices.Data.SearchFilter+IsGreaterThan([Microsoft.Exchange.WebServices.Data.ItemSchema]::DateTimeReceived, $StartDate)
        $Sflt = new-object Microsoft.Exchange.WebServices.Data.SearchFilter+IsLessThan([Microsoft.Exchange.WebServices.Data.ItemSchema]::DateTimeReceived, $EndDate)
        $sfCollection.add($Sfgt)
        $sfCollection.add($Sflt)
        $view = new-object Microsoft.Exchange.WebServices.Data.ItemView(2000000)
        $frFolderResult = $RecoverFolder.FindItems($sfCollection,$view) 
        $temp = @($frFolderResult)
        $result+= $frFolderResult
        "Current: $($temp.count)"
        "Total Count: $($result.count)"
        
#Export Results
        $temp |Select LastModifiedTime, LastModifiedName, Subject, From, DateTimeReceived  | Export-csv C:tempuser_$file_datestring.csv
        $StartDate = $StartDate.AddDays(5)
        $EndDate = $EndDate.AddDays(5)
        }While($StartDate -gt $today)

Scenario:  You need to remove a user’s photo in Exchange. You have verified that the thumbprintphoto attribute is <not set> in Active Directory, but the photo is still showing in Exchange.

Cause:  The mailbox stores a high-resolution photo in the mailbox in additional to the photo that is stored in AD.  You will need to remove it from the mailbox.

Solution:  Run the following PowerShell command to remove the photo for testuserA.

Remove-UserPhoto testuserA

Scenario: You want to determine which Exchange admin edited/altered the mailbox of a specific user HarryJ.  HarryJ could no longer access OWA as someone disabled it.  Now to determine  the admin that made the change.

Solution: Run the following:

Search-AdminAuditLog -cmdlets Set-CasMailbox -startdate “2/28/201 7:00PM” -enddate “3/1/2017  9:00AM” | Where ObjectModified -like *HarryJ* | Out-gridview

Scenario:  You want to run a Scheduled Task remotely without needing to remote into the server, open task scheduler, and execute the task.

Solution:  Run the following in Powershell with appropriate permissions:

schtasks /run /s exchsvr1 /tn "exchange monitor"

If you want to loop it so it runs manually every 30 minutes, run the following:

#When the counter reaches 30, that’s 15 hours

$counter  = 0

Do{
schtasks /run /s exchsvr1 /tn "exchange monitor"
sleep 1800
$counter++
“$counter – Running script”
} While ($counter –lt 30)

Scenario:  You have a server where you need to change the namespaceconfiguration settings of your client access virtual directories and you do not wish for this server to hand these server settings out with autodiscover.

Solution:  Run the following Powershell so it will not participate in the SCP lookup:

Set-ClientAccessServer  2016ExSrv1 -autodiscoverserviceinternaluri $null
