Receiving professional emails on your phone, without going through a browser, changes daily responsiveness. For staff at the Nantes academy, academic messaging can be set up on Android as well as on iPhone in just a few minutes, provided you know the correct server settings and have activated your account beforehand.
Activate your account on moncompte.ac-nantes.fr before any mobile configuration
Before even opening your phone’s mail application, one step blocks many newcomers. The academic account must be activated from the portal moncompte.ac-nantes.fr. Without this activation, no mobile configuration will work.
This procedure applies to contractors, substitutes, and any staff joining the Nantes academy. During the first login, the portal requires you to replace the temporary password with a permanent password that meets complexity criteria: minimum length and mandatory special characters.
In the “Security” section of the same portal, you can activate a second authentication factor (OTP). A temporary code is then sent via SMS to your mobile at each login. Several academies are generalizing this two-factor authentication for mobile access. It’s better to activate it from the start rather than being forced to do so at the beginning of the school year.
To access the academic webmail of Nantes from a mobile browser, this activation is sufficient. To receive messages directly in the native mail application, you need to go further and enter the IMAP and SMTP settings.
Nantes academy IMAP and SMTP settings: the exact values
Have you already set up a Gmail or Outlook account on your phone? The principle is the same. Your mail application needs two pieces of information: the address of the server that receives messages (IMAP) and the one that sends them (SMTP).
Here are the settings to enter for the Nantes academic messaging:
- Incoming IMAP server: imap.ac-nantes.fr, port 993, security SSL/TLS
- Outgoing SMTP server: smtp.ac-nantes.fr, port 465, security STARTTLS
- Username: your academic identifier (first.last, without the at symbol or domain)
- Password: the one defined on moncompte.ac-nantes.fr
The choice of the IMAP protocol (rather than POP) synchronizes your messages between the webmail and your phone. An email read on your iPhone will also appear as read on your computer’s browser. This is the most practical operation for daily use.
Why STARTTLS on the outgoing server and SSL/TLS on the incoming?
Both protocols encrypt the connection between your phone and the academy’s servers. The difference is technical: SSL/TLS encrypts from the start of the connection, while STARTTLS starts in clear and then switches to encrypted. The Nantes SMTP server uses STARTTLS on port 465. If your application offers “SSL/TLS” instead, try it: some versions of Android accept both on this port.
Configuration on iPhone: native Mail application step by step
On iPhone, open Settings, then “Mail”, then “Accounts”, and finally “Add Account”. Choose “Other” (not Exchange, not Google). Select “Add Mail Account”.
Enter your full academic email address ([email protected]), your password, and a display name. The next screen asks for the server settings. Select IMAP, then enter the values listed above.
If a certificate error message appears, accept the certificate to continue. This behavior is common with academic servers: the certificate is valid, but iOS requires manual validation the first time. Refusing will block all synchronization.
Once validated, your academic emails will appear in the Mail application, alongside your other inboxes. Sending messages also works, provided the SMTP server is correctly filled in.
Configuration on Android: Gmail, Samsung Mail, or third-party client
On Android, the default messaging application varies by manufacturer. Samsung Mail, Gmail, or Outlook are the most common. The logic remains the same: add an account, choose IMAP, enter the servers.
With Gmail on Android
Open Gmail, tap your avatar in the top right, then “Add another account”. Choose “Other”. Enter your ac-nantes.fr address. Gmail attempts automatic detection, which often fails with academic servers. Switch to manual configuration, select IMAP, then enter imap.ac-nantes.fr (port 993, SSL/TLS) and smtp.ac-nantes.fr (port 465, STARTTLS).
With Samsung Mail
Open the app, go to Settings, Accounts, Add Account, then “Other”. The form is similar. Be sure to check that the sync frequency is not set to “manual”: without automatic synchronization, you will not receive any notifications of new messages.
A third-party client like FairEmail or K-9 Mail also works. These applications offer more configuration options, but the server settings remain the same.
Common issues and quick solutions for Nantes academic webmail
Three situations regularly arise after configuration:
- The password is rejected even though it works in the browser. Make sure you are using your short identifier (first.last) and not the full address. Some applications automatically add the domain, creating a duplicate.
- Receiving works, but sending fails. The SMTP port or security type is likely incorrect. Try port 587 with STARTTLS if port 465 does not respond.
- Messages take several minutes to appear. Set the sync frequency to 15 minutes or less in the account settings for near-instant reception.
If the OTP two-factor authentication is activated on moncompte.ac-nantes.fr, some mail applications do not handle the temporary code. Generate a dedicated application password from the portal, in the Security section. This specific password replaces your usual password only in the phone’s mail application.
Configuration rarely takes more than five minutes when the server settings are at hand. Keep this article accessible on a second screen during the process: a typo in the IMAP server name is enough to block the entire chain.
