Switching providers
Migrate email from Natro to Microsoft 365
For a team moving from Natro XMail to Outlook and Microsoft 365, the delicate moment is the MX switch. We copy each mailbox into Exchange Online beforehand, sign in to Microsoft with OAuth rather than a password, and pick up the stragglers afterwards.
From
Natro
mail.kurumsaleposta.com
To
Microsoft 365
Natro: what to prepare
Gather each XMail address with its mailbox password; the source server is mail.kurumsaleposta.com on port 993 with SSL/TLS for everyone.
Don’t forget shared addresses such as info@ or accounting@. If they are real mailboxes at Natro, copy them one by one and decide whether they become shared mailboxes or licensed users in Microsoft 365.
When Natro runs the DNS (name servers at natrohost.com), the MX, SPF and autodiscover changes all happen in Natro’s customer panel. Write down Microsoft’s values first so you can enter them in one go.
Natro server
| IMAP server | Port | Security |
|---|---|---|
mail.kurumsaleposta.com | 993 | SSL/TLS |
Username: your full email address
Microsoft 365: what to prepare
In the Microsoft 365 admin center, add the domain, verify it with a TXT record and assign licences. Microsoft also expects an autodiscover CNAME and SPF with include:spf.protection.outlook.com.
Copy the MX target exactly as the admin center shows it (usually yourcompany-com-tr.mail.protection.outlook.com) and remove every old Natro MX record.
Microsoft 365 rejects passwords over IMAP, so the destination connects through Sign in with Microsoft (paid plans). Your tenant may need a one-time admin approval and IMAP enabled per mailbox; we check both before you pay.
Sign in with your Microsoft account
The switch, in order
Add the domain to Microsoft 365, verify it and give each XMail address a licensed user.
Make sure IMAP is enabled for each mailbox in the Exchange admin center.
In Migrabox, choose “Same address, new hosting or server” and Microsoft 365, sign in with Microsoft and copy the XMail mailboxes.
In Natro’s panel, point MX to Microsoft and add autodiscover and SPF.
When the records have propagated, click “Update now” to fetch the rest.
What isn’t copied
- Contacts, calendars, notes and tasks: export them from the old service separately if you need them.
- Filters and rules, signatures and auto-replies: set them up again in the new mailbox.
Questions about this switch
Why does Microsoft 365 need a paid plan?
Microsoft no longer accepts passwords for IMAP; only Sign in with Microsoft (OAuth) works, and that’s part of our paid plans. The one-off price starts at $4.99 and depends on mailbox size.
Will Outlook show the same folders as XMail?
Yes. Inbox, Sent, Drafts and Deleted Items map to their Outlook equivalents and every other folder is recreated with its own name.
What if our admin won’t approve Migrabox?
We spot it before payment and give you a link to send to them. Nothing is copied — and nothing charged — until approval is in place.
Ready to move your mail?
We sign in to both mailboxes and measure yours before you pay. Free up to 3 GB, then a one-off price from $4.99.
