IMAP server and port already filled in for OVH — all that's left is to enter your credentials.
IMAP settings for OVH
OVH
- IMAP server
- ssl0.ovh.net
- Port
- 993
- Encryption
- SSL/TLS
- App password
- Not required in general
OVH uses your regular mailbox password; double-check the exact IMAP server in your customer area (often ssl0.ovh.net, sometimes imap.mail.ovh.net depending on the plan).
How it works
- Enter the credentials for your OVH mailbox — the server (ssl0.ovh.net, port 993) is already filled in.
- Start the backup — MailSync connects read-only and goes through all your OVH folders.
- A .zip archive is generated — one .eml file per message, same folder structure as your mailbox.
- Download your archive — available for 48 hours after the backup finishes.
What this tool doesn't do
- The operation only works over IMAP: a mailbox reachable only via POP3, or through a closed proprietary connector, can't be used.
- The archive doesn't contain your contacts, your calendar, or the filtering rules configured on the OVH server.
- Beyond 5GB, finishing the operation requires a one-off payment or the Premium plan.
Frequently asked questions
Do I need an app password for OVH? +
No, not in the general case. OVH uses your regular mailbox password; double-check the exact IMAP server in your customer area (often ssl0.ovh.net, sometimes imap.mail.ovh.net depending on the plan).
Does the backup change my OVH mailbox? +
No. The connection to OVH is read-only: no message is deleted, moved, or even marked as read. Your mailbox stays exactly as you left it.
What format is my OVH mailbox backed up in? +
You get a .zip archive containing one .eml file per message, organized in the same folder structure as your OVH mailbox. The .eml format is an open standard, readable by Thunderbird, Outlook, Apple Mail and most email clients.
What OVH mailbox size is supported? +
The backup is free up to 5GB. Beyond that, the first 5GB are backed up for free, then you finish the operation for 4,99€ excl. VAT (5,99€ incl. VAT) or by switching to Premium, which removes this limit.
Are my OVH credentials stored? +
No. Your IMAP credentials are encrypted with libsodium for the duration of the operation, then erased as soon as it finishes. If you're signed in to your MailSync account and choose to save the mailbox, only that one is kept (encrypted); you can delete it at any time.
