How to connect your OVH mailbox to Claude and ChatGPT

To use an OVH mailbox in Claude or ChatGPT, you connect it over IMAP through an MCP server, then add that server to your assistant. With Fezola, you choose OVH in the list (the servers ssl0.ovh.net, ports 993 and 465, are filled in), type your mailbox password, and paste one URL into Claude or ChatGPT. It takes about two minutes and nothing has to be installed.

Why OVH mail needs a connector

OVHcloud hosts the email of thousands of small businesses, freelancers and associations on their own domain (contact@your-company.com). As of November 2026, the built-in mail connectors of Claude and ChatGPT target large providers such as Gmail. A mailbox at OVH is a standard IMAP mailbox, so the assistant needs an IMAP MCP server to reach it.

Fezola is a hosted one: you add the mailbox once on the Fezola website, and your assistant signs in to Fezola with OAuth. The mailbox password never goes through the assistant's settings or the chat.

The OVH settings, offer by offer

OVH offer	In Fezola, choose	Incoming (IMAP)	Outgoing (SMTP)	Login
MX Plan (email included with a domain or web hosting)	OVH	ssl0.ovh.net, port 993, TLS	ssl0.ovh.net, port 465, TLS	full email address
Email Pro	Other	pro1.mail.ovh.net, port 993, TLS	pro1.mail.ovh.net, port 587, STARTTLS	full email address

Not sure which offer you have? In the OVHcloud Control Panel, open the Web Cloud tab, then Emails: MX Plan mailboxes are listed under your domain, Email Pro has its own section. If OVH shows you different server names in the Control Panel, use those: in Fezola every server and port can be changed under "Server settings".

OVH does not use app passwords: the login is the full address and the password is the one of the mailbox (the one you use in OVH webmail), not the password of your OVHcloud customer account.

Setup in four steps

1. Create a free Fezola account and open Sources.
2. Add the mailbox: choose OVH (or Other for Email Pro), enter the address and the mailbox password, and give it a short name such as "Company". Your assistant uses that name to say where each message comes from. Click "Test the connection": Fezola checks incoming (IMAP) and outgoing (SMTP) mail.
3. Add Fezola to your assistant. In Claude: Customize, Connectors, + Add, Add custom connector, name it Fezola and paste https://api.fezola.com/mcp. In ChatGPT (paid plans): Settings, Apps & Connectors, Advanced settings, turn on Developer mode, then create a connector with the same URL and OAuth.
4. Approve the access on the Fezola consent screen, then ask your first question.

What you can ask

• "What did clients write to contact@ this week? Group by urgency."
• "Find the last quote sent by our accountant and summarize the PDF."
• "Draft a reply to the last email from Martin, from the company address."
• "Search my OVH mailbox and my Gmail for the invoice from the printer."

Attachments are readable (PDF, Word, text and images), and when several mailboxes are connected, every result names its account, so you always know whether a message came from the OVH address or another one.

What the assistant cannot do

• It does not send. Replies are saved as drafts in the OVH mailbox that received the original message, with that address as the sender. You review and send them yourself, from your mail app or OVH webmail.
• It does not keep a copy of your mail. Messages are read live from OVH when the assistant asks.
• It only acts when asked. Archiving, moving or flagging happens on request. If your OVH mailbox has no Archive folder, Fezola creates one the first time you archive, as Apple Mail or Thunderbird do.

For the security side (what is stored, how to revoke access), read is it safe to connect your email to an AI?. Other hosts (IONOS, Gandi, Fastmail, your own server) work the same way: see the IMAP MCP server guide. And if you also have Gmail or iCloud, the all your inboxes guide shows how to search them together.

Common errors

• "Username or password rejected": check that you use the full address as login and the password of the mailbox, not the OVHcloud account password. If you recently changed it in the Control Panel, update it in Fezola.
• Server unreachable: you probably picked the wrong offer. Email Pro mailboxes do not answer on ssl0.ovh.net; choose Other and enter the Email Pro servers.
• Status "Error" in your assistant: ask it to test the connection. Fezola returns a plain explanation of what failed.
