Update POP3 Connector

Audience: Low-code Engineers, System/Security Administrators

Skill Prerequisites: Actions, Tokens, Connectors

Changes an existing POP3 connector, found by its ID. It replaces the connector's title, server, sign-in details and custom data with the values in the action.

The action has one field for each POP3 setting, so you don't need to know the property names. To change connectors of any type, use Update Connector.

note

This action requires the Email Sync feature to be licensed.

caution

The POP Mail trigger that uses POP3 connectors is obsolete. For new applications, use IMAP with Add Imap Connector instead.

Typical Use Cases

• Save a new password after a user changes their mailbox password
• Move a POP3 mailbox connector to a new mail server

Don't use it to

• Add a connector. Use Add POP3 Connector instead.
• Change an IMAP connector. Use Update Imap Connector instead.
• Move a connector to another group. The group can't be changed.

Related Actions

Action Name	Description
Add POP3 Connector	Adds a POP3 connector and returns its ID.
Get Connector	Reads a connector's data.
Update Connector	Changes a connector of any type.
Delete Connector	Deletes a connector.

Input Parameter Reference

Parameter	Description	Supports Tokens	Default	Required
Entry Id	The ID of the connector to change, a GUID. It's usually a token, for example [Pop3EntryId].	Yes	empty string	Yes
Entry title	The new name of the connector.	Yes	empty string	No
POP3 Server	The POP3 server, for example pop.example.com. To use a port other than the default, add it after a colon, for example pop.example.com:1995.	Yes	empty string	No
Use SSL	true to connect with SSL/TLS, false to connect without it.	Yes	empty string	No
Username	The username or email address used to sign in.	Yes	empty string	No
Password	The password used to sign in. It's stored encrypted. Enter ****** to keep the current password.	Yes	empty string	No
Custom Data	Extra name/value pairs to store with the connector.	Yes	None	No

Considerations

• Every value is replaced. Empty fields clear the stored value, including Entry title. Custom data that isn't in the action is removed. Fill in every field, not just the ones that change. To keep the password, enter ******.
• Get the current values first. To change only one value, read the connector with Get Connector and pass the other values back as tokens.
• The connector must exist. If Entry Id is empty, the action fails with Data was not saved due to an invalid EntryId!. If no connector has that ID, the action fails with Requested connector, with id '<Entry Id>', does not exist. An ID that isn't a valid GUID also fails.
• The type isn't checked. Only use this action with POP3 connectors.
• Default ports. The connection uses port 995 when Use SSL is true and port 110 when it's false, unless the server includes a port.

Examples

tip

To understand how to use the below examples, please see Running Examples.
