Hey @Anonymous

You could use the Search for users action to know if an user exists or not.

And then Get user profile action to get the UPN or email from the user that has been searched.

I recreated your Flow with your information given.

Hope this helps

Kind regards

Hi @Anonymous,

Have @Tom_Slosse's answer solved your question?

Do you want to check if the response of the "User search" is empty?

You could use "Search for users" action to search the user,please refer to screenshot below to create the flow:

The expression in the condition as below:

@equals(length(body('Search_for_users')), 0)

The flow would run successfully to check if the user exists.

If the user exists, the flow would get the user's email as screenshot below:

If the user don't exists, the flow would do nothing as screenshot below:

Solution for Finding Users Not in O365 / Not Working for the Company Anymore / Offboarding Emails

In my case the solution needed to check all registered 'Authors' and 'Owners' of documents in a Sharepoint library, find any users that were no longer working for the company, and then send alert emails so new Owners or Authors could be assigned the documents.

The challenge was getting a Compare function to match users that were not found in the O365 tenancy, as using the Search For User function simply returned an empty object, which I couldn't then get the Condition function to recognise.

The answer was to use Compose function with the Length expression first to render an output integer for the length of the response to the user Search, which would then allow the Condition function to operate on it.

Solution

1. Recurrence function - so the job runs weekly 
2. Get Items (Sharepoint) function to call the Sharepoint Library
3. Apply to Each function, using the 'value' from the Get Items step - @{outputs('Get_items')?['body/value']} 
   1. Search For User v2 (O365), searching with an an outputted User field value from the Get Items step (in my case, Document Author Display Name)
   2. Compose function, using a Length expression to output a number - @{length(body('Search_for_users_(V2)')?['value'])}
   3. Condition function, using the Outputs from the Compose step, Is Less Than, 1. This will answer True if a user is not found in O365 as the response body's  value is empty and has 0 length.
      1. If True: Send an Email function
      2. If False: do nothing
4. Terminate

Hi @v-yuazh-msft !

Sorry to bring back an old post, I would like to know how to changed modes in your condition. I can't find a button to change modes.
