Question

Outlook/Hotmail: Cannot receive a confirmation email after registering at https://xtrf...

Zuzana Kapustova 20

Hello,

After registering my email address (******@hotmail.sk) at a registration page starting with https://xtrf...." I am supposed to receive a confirmation email to proceed with the registration process, but I do not receive any email - either in my Inbox or in the Spam folder or after requesting it to be resent. No error or warning message displays.

I have not found any related setting in my Outlook or in my MS account to solve this issue myself.

Could you, please advise what could be the reason for not receiving the confirmation email?

I use Outlook.com on my Windows 11, my email address ends with "hotmail.sk".

Please, let me know if further information is needed.

Thank you for your help.

Hi, Zuzana Kapustova

Since the confirmation is missing even after resending, I wouldn’t repeat the same Inbox checks. The information available doesn’t establish whether the registration site sent the message successfully or whether delivery failed.

Here are some suggestions you can try:

First, return to the registration page and check that the address entered ends in hotmail.sk, not hotmail.com, and contains no typing mistakes. This is worth checking before changing anything in Outlook.

As an alternative, you could try registering with a new outlook.com alias attached to your existing Microsoft account. An alias is an additional email address that uses the same inbox, so you wouldn’t need to manage another mailbox.

To create one, open your Microsoft account’s Your info > Edit account info, select Add email, and create a new Outlook.com address. Keep your existing Hotmail address. Then, if you’re comfortable making a separate registration attempt, use the new address on the vendor site. This is a workaround to try, not a guaranteed fix.

Hello Kai-H,

Thank you for the suggested solutions. I have created a new account with the "outlook.com" alias and tried to login to my e-mail using that e-mail and it seems to work fine.

However, I cannot try to use it for registering to the vendor database mentioned above, since in the meanintime I have registered there using my gmail address.

In any case, now when I have the .outlook.com address I will try to use it in the future, should I have problems registering with the .hotmail.sk alias.

For now, please consider my question answered.

Thank you for your help.

Hi, Zuzana Kapustova

Thanks for the update, and I'm glad the new outlook.com address is working.

Using your Gmail address for the vendor database is fine. It doesn't affect your Microsoft account in any way. If you'd rather have Microsoft-related mail in one place later, check whether the vendor portal lets you change the contact email in your profile settings. Many sites allow this without making you register again.

A few quick tips so the new address keeps working smoothly:

If you added outlook.com as an alias on your existing account: you can keep using either address to sign in, and both deliver to the same inbox. You can also send from the new alias. In Outlook.com, go to Settings > Mail > Compose and reply and pick it as your default "From" address. That way, any site you register on sees the outlook.com address.

If you created a completely separate account: add a recovery phone number and a backup email under account.microsoft.com > Security. That will help if you ever need to recover it.

If a site rejects your hotmail.sk address again: it's usually the site's form not accepting less common regional domains, not a problem with your mailbox. The outlook.com address is a good fallback for those cases.

Hello Kai-H,

Thank you for the helpful tips.

I have set the @outlook.com as the default From address (the setting is under Settings > Mail > Synchronize emails in my Outlook) as you suggested.

Then I tried to send an e-mail from the Outlook account to my Gmail account and it was received correctly in Gmail. However, when I checked the sender's email address in the received email, it showed hotmail.sk, not outlook.com. Is this an expected behaviour?

I suppose it is because outlook.com is not set as a primary email address in my MS account. I tried to set it as a primary one in the MS account, but an error appeared saying that it is not possible right now.

Could you, please clarify the behaviour if my assumption is incorrect?

No need to reply during the weekend.

Thank you

Hi, Zuzana Kapustova

Thanks for testing this and sharing the details. Your assumption is mostly correct.

Why Gmail shows hotmail.sk:

To change the default From address in Outlook.com, you need to update your primary alias. The default From option under Sync email only pre-fills the address in new messages in Outlook on the web. It doesn't change your account's primary identity. Also, messages sent from the Outlook mobile app, new Outlook for Windows or other mail clients will generally still go out from the primary address.

Until the primary is changed, you can still send from the outlook.com address on any message:

In Outlook on the web, open a new message.

If the From line isn't visible, go to Options > Show From.

Select the outlook.com address in the From dropdown, then send another test to Gmail.

If Gmail still shows hotmail.sk after you've picked the alias manually, sign out of Outlook.com and back in, then try again. Some users found that the alias only worked after a fresh sign-in.

About the "not possible right now" error:

This message is fairly common, and it usually has one of these causes:

Change limit: you can change your primary alias only twice in a rolling 7-day period. There is also a cap of about 10 changes per year.

Recent account changes: if you recently added the alias or changed your password or security info, the account may be temporarily restricted. Waiting and trying again later usually helps.

Misleading error: sometimes the error appears even though the change went through. Reload Manage how you sign in to Microsoft after a minute and check which address is marked as primary.

Propagation delay: after a successful change, it can take up to 48 hours to show up across all Microsoft services.

I'd suggest waiting a day or two and then trying again in an InPrivate/Incognito window with any VPN turned off. If that fails, try from a phone on mobile data.

One important caution: don't remove the hotmail.sk alias, even after outlook.com becomes primary. If you remove an alias on a Microsoft domain, it's permanently deleted and can't be added back to any account.

Hello Kai-H,

Thank you again for the useful tips. I will save them for later use, I suppose your answers will not be displayed on this page for ever.

I have displayed the "From" line in a new message, but did not have to select the Outlook.com from the drop-down list since it was already selected.

I sent a test mail to my Gmail inbox and indeed, the From filed shows "outlook.com" now. I guess it just needed some time for the change to apply.

I do not plan to remove the hotmail.sk address, there is no reason for that, if the outlook.com and hotmail.sk route emails to the same inbox. I just need to explain to the receivers, if needed, why they see outlook.com instead of hotmail.sk, if needed.

I think everything is clear now.

Thank you very much again for your help and patience.
