What does Outlook Username Checker do?

Outlook Username Checker tells you instantly whether an Outlook or Hotmail email address is available or already taken. Give it a list of usernames, and it returns availability status plus Microsoft's own alternative suggestions for taken names — all via the Apify platform with scheduling, API access, and monitoring built in.

Why use Outlook Username Checker?

Check dozens of usernames in a single run instead of one by one in a browser
Get Microsoft's suggested alternatives automatically when a name is taken
Integrate results into your workflow via the Apify API or webhooks
Schedule regular checks to catch when a username becomes available

How to use Outlook Username Checker

Open the Input tab in Apify Console.
Add the usernames you want to check — you can enter just the username (e.g. john.doe) or the full address (e.g. john.doe@outlook.com).
Optionally adjust Delay Between Requests if you're checking many names.
Click Start and wait for the run to finish.
Open the Output tab to see results, or download them as JSON, CSV, or Excel.

Input

Field	Type	Description	Default
`usernames`	string list	Usernames or full addresses to check	—
`delayMs`	integer	Milliseconds between requests (500–10000)	`1500`

Example input:

{
  "usernames": ["john.doe", "jane.smith", "coolname99@outlook.com"],
  "delayMs": 1500
}

Output

One record per username is pushed to the dataset.

[
  {
    "username": "john.doe",
    "signInName": "john.doe@outlook.com",
    "isAvailable": false,
    "suggestions": ["john.doe1@outlook.com", "john.doe2026@outlook.com"]
  },
  {
    "username": "xk9r2qvw",
    "signInName": "xk9r2qvw@outlook.com",
    "isAvailable": true,
    "suggestions": []
  }
]

You can download the dataset in various formats such as JSON, HTML, CSV, or Excel.

Data table

Field	Format	Description
`signInName`	text	Full email address checked
`isAvailable`	boolean	`true` if the username is free
`suggestions`	array	Microsoft's alternatives (only when taken)
`username`	text	Original input value

Tips

Keep delayMs at 1500 ms or above when checking more than 20 usernames.
You don't need to add @outlook.com — the Actor handles it automatically.
If isAvailable is null in the output, that request encountered an error; retry or increase the delay.
