Updated January 2026.
Need a temporary Outlook address for a signup, verification code, or spam control? There isn’t an official “temporary Outlook generator” that creates inboxes that expire automatically—but you do have several practical options that accomplish the same goal.
In this guide you’ll learn what actually works in 2026: Outlook +tag addresses (for filtering), Outlook aliases (recoverable separation), a second Outlook inbox, and a true disposable inbox for one‑time OTP codes.

Quick answer: the best way to get a temporary Outlook address
Use this decision tree:
- You mainly want filtering / leak tracking: use Outlook +tag (site‑specific addressing).
- You want a separate identity that’s still recoverable: use an Outlook alias.
- You want a totally separate mailbox for signups: create a second Outlook/Hotmail account.
- You want a true throwaway address for one‑time OTP codes: use a disposable inbox (fastest) like Anonibox.
- You might keep the account (password resets later): use an email alias (not disposable) so you stay recoverable: Email Alias (2025).
If you’re stuck because the verification email isn’t arriving, jump to: Verification Email Not Received (Temp Mail)? Fix It Fast (2026).
What people mean by “temporary Outlook address”
When someone searches for “temporary Outlook address,” they’re usually trying to achieve one of these outcomes:
- Spam protection: keep your primary inbox off marketing lists.
- One-time access: get a code/link, then discard the address.
- Compartmentalization: separate signups from personal email.
- Tracking control: identify which site leaked or sold your address.
Different tools solve different outcomes. The next sections show the options and the tradeoffs.
Option 1: Outlook +tag addressing (site-specific addresses)
Outlook.com supports “site-specific” addressing where you append +tag to your existing address. For example:
yourname+shopping@outlook.comyourname+newsletters@outlook.comyourname+trial@outlook.com
When +tag is the best choice
- You want filtering (rules/folders) without creating new accounts.
- You want leak tracking (“which site shared my email?”).
- You don’t mind that it still reveals your base address.
Important limitations
- Not guaranteed to work on every website. Some signup forms reject “+”.
- It’s not privacy. Most recipients can infer your base address is
yourname@outlook.com. - It’s not “disposable.” Messages still land in your real mailbox.
Tip: If a site rejects “+” or you want a true throwaway address, use a disposable inbox instead: Anonibox.
Option 2: Outlook aliases (recoverable separation)
An Outlook alias is a second email address connected to the same Microsoft account. It routes mail into the same mailbox, but it can give you a cleaner “identity boundary” than +tag (depending on your use case).
Why aliases are useful
- Recoverable: good for accounts you might keep (password resets).
- Cleaner separation: you can use one alias only for signups.
- Less “form rejection” risk: many forms that reject “+” still accept normal-looking aliases.
What aliases are NOT
- They are not disposable (they don’t automatically expire).
- They are not anonymous (still tied to a single Microsoft account).
If you want “privacy with recovery” across many services (and a kill switch when one address is leaked), an email-alias strategy is often the best long-term solution: Email Alias (2025).
Option 3: Create a second Outlook/Hotmail account (separate inbox)
If you want full separation—different mailbox, different inbox rules, different login—creating a second Outlook account is the simplest approach.
Pros
- True separation (no mixing with your main inbox)
- Works well for sites that block disposable domains
- Recoverable long-term
Cons
- You must maintain another inbox (noise, security, 2FA)
- It becomes a long-term identifier if you reuse it everywhere
- More friction than disposable email for one-off codes
Best practice: treat the second inbox as a “signup-only mailbox.” Don’t store sensitive accounts there. Keep 2FA enabled and use a password manager.
Option 4: Use a disposable inbox (fastest throwaway option)
If your goal is simple—get an OTP code or confirmation link and move on—then a disposable inbox is usually the fastest tool.

Best for
- OTP / verification codes
- Download links (“we’ll email the PDF” gates)
- Low-stakes signups you won’t keep
- Quick access workflows (Wi‑Fi portals, giveaways, etc.)
Not recommended for
- banking, healthcare, taxes, legal portals, or government logins
- paid subscriptions, invoices, receipts
- any account you might need to recover later

Outlook +tag vs Outlook alias vs disposable inbox
| Option | Best for | Recoverable? | Privacy level | Common downside |
|---|---|---|---|---|
| Outlook +tag | Filtering & leak tracking | Yes (it’s your mailbox) | Low (reveals base address) | Some forms reject “+” |
| Outlook alias | Separation with recovery | Yes | Medium | Still tied to same account |
| Disposable inbox | One-time OTP codes | No (by design) | High (fresh address) | Some sites block disposable domains |
What to do when a website blocks your “temporary” address
Two common scenarios:
- Hard block: “Invalid email” immediately.
- Soft block: email is accepted, but the verification email never arrives.
Here’s the clean approach (no “bypass tricks”):
- If you might keep the account: switch to an alias (recoverable).
- If you only need spam separation: use a secondary mailbox you control.
- If it’s low-stakes: try one fresh disposable address and one resend cycle.

Troubleshooting: verification email not received
If you’re using a disposable inbox and you’re not receiving the verification email, follow this order:
- Wait 60–90 seconds. OTP emails can be queued.
- Resend once. Repeated resends can trigger throttling.
- Keep the inbox tab open. Mobile background tabs sleep.
- Try a new address. New signup → new inbox.
- If it still fails: assume blocking → switch to an alias.

FAQs
Can I create a temporary Outlook email address without signing up?
Outlook doesn’t provide a built-in “temporary address generator” that creates a brand-new Outlook inbox without signup. If you need a true throwaway address for an OTP code, use a disposable inbox like Anonibox.
Is Outlook +tag the same as a disposable address?
No. A +tag address still delivers to your real mailbox. It’s mainly for filtering and leak tracking, not for “use once and discard.”
What’s the safest option for accounts I might keep?
Use an alias (recoverable) instead of disposable email. Start here: Email Alias (2025).
What should I use for one-time verification codes?
A disposable inbox is usually the fastest. Start with Anonibox temporary email generator.
Conclusion
A temporary Outlook address usually means “I want to protect my real inbox.” In 2026, the clean options are:
- Outlook +tag for filtering and leak tracking,
- Outlook aliases for recoverable separation,
- a second Outlook inbox for full separation, or
- a disposable inbox for one‑time OTP codes.
