Certified Electronic Mail (PEC) is a cornerstone of digitalization in Italy, combining the legal tradition of registered mail with the innovation of electronic communication. This tool, now indispensable for professionals, companies, and citizens, allows you to send and receive messages with the same legal value as a registered letter with return receipt. Integrating PEC into your favorite email client, like Microsoft Outlook, means centralizing communications and optimizing your workflow. Correctly configuring the account ensures direct, secure, and immediate access to all emails, certified and otherwise, from a single interface.
In a Mediterranean context where personal relationships and trust are fundamental, PEC serves as an element of certainty in the digital world. With nearly 16 million active mailboxes in Italy and a volume of 2.5 billion messages exchanged in 2023, the numbers confirm its growing adoption. Its upcoming evolution into an interoperable European standard, compliant with the eIDAS regulation, will further amplify its scope, projecting an Italian specialty into the broader European digital single market. This guide offers a detailed path to configure PEC in Outlook, making this technology accessible to everyone.
What is PEC and Why It’s Different from Traditional Email
Certified Electronic Mail (PEC) is an email system that provides legal proof of the sending and delivery of a message. The substantial difference from a traditional email lies precisely in its legal value. While a regular email offers no guarantees about receipt or content integrity, PEC certifies the sender’s identity, the date and time of sending, and the certainty of delivery to the recipient. This process occurs through acceptance and delivery receipts issued by certified email providers, who act as third-party guarantors. In practice, PEC is the digital equivalent of a traditional registered letter with acknowledgment of receipt.
In addition to its legal value, PEC offers a higher level of security. Communications are protected by encryption protocols that ensure their integrity and inalterability, preventing changes to the content and any attachments. This makes it the ideal tool for formal communications with Public Administrations, for transmitting contracts, invoices, and sensitive documents. The requirement for businesses and professionals to have a digital domicile has further consolidated its role, making it not just a useful tool, but often an indispensable one in the Italian professional and bureaucratic landscape.

The Necessary Parameters for Configuration: IMAP or POP3
To configure a PEC account in Outlook, it’s essential to know your provider’s parameters. The key information includes the server names for incoming mail (IMAP or POP3) and for outgoing mail (SMTP), as well as their respective ports and security settings. The choice between IMAP (Internet Message Access Protocol) and POP3 (Post Office Protocol 3) depends on your needs. IMAP is the recommended choice for those who check their mail from multiple devices, as it synchronizes messages by keeping them on the server. This way, any change (reading, deleting, moving) is visible from any device. POP3, on the other hand, downloads messages to the local device, removing them from the server (unless configured otherwise), a solution suitable for those who use a single computer.
Regardless of the chosen protocol, security is an essential requirement. The configuration requires the use of encrypted SSL/TLS connections for both the incoming and outgoing servers. The standard ports are generally 993 for IMAP and 995 for POP3, while the port for the outgoing SMTP server is 465. You also need to enable authentication for the outgoing mail server (SMTP), using the same credentials as the incoming mail account. These parameters are provided by your PEC provider (such as Aruba, Poste Italiane, Legalmail) when the mailbox is activated.
Parameters of Major PEC Providers
Each Certified Electronic Mail provider uses specific parameters. Below are the configuration details for some of the most popular providers in Italy, to be used during the manual setup of your account in Outlook.
- Aruba PEC: IMAP Server: imaps.pec.aruba.it (port 993)
- POP3 Server: pop3s.pec.aruba.it (port 995)
- SMTP Server: smtps.pec.aruba.it (port 465)
- SMTP Authentication: Required (use the same credentials as for incoming mail)
- Security: SSL/TLS
Poste Italiane (Postecert):
- IMAP Server: mail.postecert.it (port 993)
- POP3 Server: mail.postecert.it (port 995)
- SMTP Server: mail.postecert.it (port 465)
- SMTP Authentication: Required
- Security: SSL
Legalmail (InfoCert):
- IMAP Server: mbox.cert.legalmail.it (port 993)
- POP3 Server: mbox.cert.legalmail.it (port 995)
- SMTP Server: sendm.cert.legalmail.it (port 465)
- SMTP Authentication: Required
- Security: SSL/TLS
It’s important to always check your provider’s official documentation, as the parameters may change. Also, if two-factor authentication is enabled, you may need to generate an app-specific password to use instead of your main password.
Step-by-Step Guide to Adding PEC to Outlook
Adding a PEC account to Microsoft Outlook is a simple process if you follow the correct steps. The procedure may vary slightly depending on your Outlook version (Microsoft 365, 2019, 2016), but the basic logic remains the same. Manual configuration is almost always necessary to enter the specific parameters of your PEC provider. Let’s see how to proceed in the latest version of Outlook for Windows.
- Start the process: Open Outlook and go to File in the top-left corner. Select Add Account.
- Enter the PEC address: In the window that opens, type your full PEC address (e.g., yourname@pec.it). Click on Advanced options and check the box “Let me set up my account manually”. Press Connect.
- Choose the account type: Outlook will ask you to choose the account type. Select IMAP (or POP, if you prefer).
- Enter the server parameters: Fill in the fields for incoming and outgoing mail with the parameters provided by your provider (server, port, SSL/TLS encryption method).
- Configure authentication: Ensure that authentication is required for the outgoing mail server (SMTP) and that it uses the same settings as the incoming server.
- Enter the password and finish: Type your PEC account password (or the app-specific password, if required) and click Connect. Outlook will verify the settings and, if they are correct, the account will be added successfully.
Once the configuration is complete, the PEC mailbox will appear in Outlook’s navigation pane, ready to use. For even more efficient management, you can consider setting up rules in Outlook to automatically organize incoming certified messages.
PEC and the European Digital Future: The eIDAS Regulation
Originating as an Italian specialty, PEC is evolving to become a legally recognized communication tool throughout the European Union. This change is driven by the eIDAS Regulation (electronic IDentification, Authentication and Trust Services), which establishes a common legal framework for secure electronic transactions between citizens, businesses, and public administrations of member countries. The goal is to create a digital single market where identification tools and trust services, like PEC, are interoperable across national borders.
The adaptation of Italian PEC to the European standard will transform it into a Qualified Electronic Registered Delivery Service (QERDS), also known as REM (Registered Electronic Mail). This will guarantee not only the certainty of sending and receiving but also the certain identification of the sender and recipient, strengthening security and trust in cross-border communications. For users, this means that starting from June 2024, it is necessary to upgrade their PEC mailbox to maintain its full legal value. This transition projects Italian innovation into a broader context, consolidating PEC as a fundamental tool for the European digital future.

Frequently Asked Questions
The server parameters vary depending on the PEC provider. However, the general configuration requires an incoming mail server (IMAP) and an outgoing mail server (SMTP). For IMAP, the address is often similar to `imaps.pec.domainname.it` with port 993 and SSL/TLS encryption. For SMTP, the address is usually `smtps.pec.domainname.it` with port 465 and SSL/TLS encryption. It is crucial to verify the specific parameters provided by your PEC provider, such as Aruba, Legalmail, or Poste Italiane, as they may differ slightly.
The choice between IMAP and POP3 depends on your needs. **IMAP** (Internet Message Access Protocol) is recommended if you check your PEC from multiple devices (computer, smartphone, tablet). It keeps messages on the server, synchronizing all folders and actions (reading, deleting) on every device. **POP3** (Post Office Protocol 3), on the other hand, downloads messages to the first device that connects, removing them from the server (unless specified otherwise). This option is suitable if you use only one computer for PEC and want to free up server space, but it makes management from multiple locations difficult.
Sending/receiving issues can be due to several factors. First, check the correctness of the server parameters (IMAP/POP3 and SMTP), ports (993/995 for receiving, 465 for sending), and that SSL/TLS encryption is active for both. Make sure that authentication for the outgoing mail server (SMTP) is enabled and uses the same credentials as the incoming mail. Another common cause, especially with IMAP, is an incorrect ‘root folder path’: in some cases, it must be set to ‘INBOX’ in the advanced account settings to display the inbox correctly.
Yes, it is often necessary. If you have enabled two-factor authentication (2FA) on your PEC account, for security reasons you cannot use your main password to log in from email clients like Outlook. You must generate an ‘app password’ or ’email program password’ directly from your PEC provider’s management panel. This application-specific password should then be entered in the password field during the account setup in Outlook. Remember that this dedicated password often has a periodic expiration.
Certainly. Outlook allows you to configure and manage multiple email accounts simultaneously, including multiple PEC accounts. To add a new account, simply follow the standard procedure: go to ‘File’, click on ‘Add Account’, and enter the details and parameters of the new PEC address you wish to configure. This allows you to manage certified communications from different addresses (for example, a personal one and a business one) directly from the same Outlook interface.
