Ou Picker Not Working Again After Cu7

Issue: Commutation 2016 CU5 , OU Picker is not showing Users within EAC ( Exchange Admin Middle)

Cause: Web.config file needs to be modified "GetListDefaultResultSize" needs to be added with > number of existing OU ( Organizational Units) within the surround.

Notes: Web.config file is located on default substitution install directory under ECp folder "Program Files\Microsoft\Commutation Server\V15\ClientAccess\ecp"

It needs to exist added with notepad ( opened with administrator privileges)

Each CU install will wipe these settings, therefore spider web.config file needs to be saved each fourth dimension prior installing CU on Exchange 2016 Servers.

I have added few simple scripts to aid you to develop baselines to implement in your environment

Web.config file is not server dependent, single file can be modified/saved and moved around Exchange 2016 servers, if desired.

• Log onto Commutation 2016 Server, via RDP (Remote Desktop Protocol)
• Provide your credentials at the logon.
• Click windows tile and select PS (PowerShell)
• Select to open PowerShell with ambassador privileges
• Blazon post-obit press enter (note the installed directory)

$exinstall\ClientAccess\ecp

• Type notepad on the PowerShell (Open notepad with administrator privileges)
• Click file and select Open up on the administrative notepad
• Drill down to ECP directory under Installed directory ;
• Plan Files\Microsoft\Exchange Server\V15\ClientAccess\ecp
• Locate web.config ( make sure on the bottom change to all files to locate the web.config)
• Open web.config file

Printing CTRL + F to bring upward find menu and blazon "</appSettings>"

• Locate the section
• Add together this line ( it does non be in Commutation 2016 )

# below line must be edited in a higher place "</appSettings>" Department within the Web.Config File

<add together key="GetListDefaultResultSize" value="1500" />

• Comments Added ( same line with comments)

<!-- Each CU Install will Wipe This File. -->

<!-- Save a backup copy of web.config file -->

<!-- After CU install y'all can copy and paste backup spider web.config file -->

<add primal="GetListDefaultResultSize" value="1500" />

• Open up another PS window and re-create and paste i line to go the number of OU's in your environment and note the settings.

# You tin can easily get your current OU count with simple one liner

# Getting OU count

(Get-OrganizationalUnit).count

• Close web config
• From PowerShell Type

Restart-WebAppPool MSExchangeECPAppPool

• Perform same job on Each Substitution 2016 Server listed below

Verification

• Open web browser and type post-obit URL press enter, supervene upon the server proper name with proper server name that is applicable for your environs

https://EX101/ecp/default.aspx

• Provide your credentials
• Click Recipients
• Click New, User Mailbox
• Select new user
• Click Browse
• Brand certain Under "Select an Organizational Unit" Section populates the OU Structure

• You will be able to see the OU'south
• PS scripts to

# Connect Remote Exchange 2016 Server, Specify Server to connect.

# Change the server FQDN with server name you have.

Office Connect_E16 {

param(
