Description
You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
Examples
Example 1
Set-PopSettings -Server "MBX01" -UnencryptedOrTLSBindings 10.0.0.0:110
This example configures the unencrypted or STARTTLS encrypted POP3 connection to the server named MBX01 by using the local IP address 10.0.0.0 on TCP port 110.
Example 2
Set-PopSettings -ProtocolLogEnabled $true -LogFileLocation "C:\Pop3Logging"
This example turns on POP3 protocol logging. It also changes the POP3 protocol logging directory to C:\Pop3Logging.
Example 3
Set-PopSettings -LogPerFileSizeQuota 2MB
This example changes the POP3 protocol logging to create a new log file when a log file reaches 2 megabytes (MB).
Example 4
Set-PopSettings -LogPerFileSizeQuota 0 -LogFileRollOverSettings Hourly
This example changes the POP3 protocol logging to create a new log file every hour.
Example 5
Set-PopSettings -X509CertificateName mail.contoso.com
This example specifies the certificate that contains mail.contoso.com is used to encrypt POP3 client connections.
Note: For single subject certificates or a SAN certificates, you also need to assign the certificate to the Exchange POP service by using the Enable-ExchangeCertificate cmdlet. For wildcard certificates, you don't need to assign the certificate to the Exchange POP service (you get an error if you try).
Parameters
-AuthenticatedConnectionTimeout
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
The AuthenticatedConnectionTimeout parameter specifies the time to wait before closing an idle authenticated connection.
To specify a value, enter it as a time span: dd.hh:mm:ss where dd = days, hh = hours, mm = minutes, and ss = seconds.
Valid values are 00:00:30 to 1:00:00. The default value is 00:30:00 (30 minutes).

The CalendarItemRetrievalOption parameter specifies how calendar items are presented to POP3 clients. Valid values are:
- 0 or iCalendar. This value is the default.
- 1 or IntranetUrl.
- 2 or InternetUrl.
- 3 or Custom.
If you specify 3 or Custom, you need to specify a value for the OwaServerUrl parameter.

-Confirm
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
- Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax:
-Confirm:$false. - Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

- Require: Extended Protection for Authentication is required for all POP3 connections. If the incoming POP3 connection doesn't support it, the connection is rejected.
Extended Protection for Authentication enhances the protection and handling of credentials by Integrated Windows authentication (also known as NTLM), so we strongly recommend that you use it if it's supported by your clients (default installations of Windows 7 or later and Windows Server 2008 R2 or later support it).

-X509CertificateName
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
The X509CertificateName parameter specifies the certificate that's used for encrypting POP3 client connections.
A valid value for this parameter is the FQDN from the ExternalConnectionSettings or InternalConnectionSettings parameters (for example, mail.contoso.com or mailbox01.contoso.com).
If you use a single subject certificate or a subject alternative name (SAN) certificate, you also need to assign the certificate to the Exchange POP service by using the Enable-ExchangeCertificate cmdlet.
If you use a wildcard certificate, you don't need to assign the certificate to the Exchange POP service.
