Office 365 Users - Search for users - partial email search not working

I am attempting to use the Office 365 Users - Search for users to search for users with a specific domain. For example, I want all users with email addresses that end with


When I search on a complete email it returns just fine. When I do a partial search on a name such as David, no problem, returns all expected users. When I do a partial search on a term like mith (S is purposefully removed) it will return all Smith's in our system. But when I try a partial email it returns nothing.


Is there a way to have Office 365 Users - Search for users successfully search on partial email addresses?


Thank you!

Hi @Hyggins,


You could use Search for users to get all the user information, and then use Filter array to get all the user information of the Email address containing the specified domain.

Hello @v-bacao-msft,


Thank you so much for this reply and example! Unfortunately, this will not work in my case. We have well over 1000 users and the Search for users throws an error if I go over 999. So I was trying to find out how to use the search action itself to limit the output to below 1000.


Currently, using a method very similar to the one you posted, the Search it pulls the first 999 users. Of those users about 230 make it through the filtering process. This only gets me about half way through first names that begin with J.


I was hoping there would be some other options with the Search for user action.


Thanks again for your post!

Hi @Hyggins 

You can try using the Graph API to fetch the list of users using ODATA filters. Please try to look into the below link

Unfortunately this doesn't not seem to be supported at this time.


From Microsoft:


"The contains string operator is currently not supported on any Microsoft Graph resources."


Thank you!

hi @Hyggins ,


Finally, I got a solution by using "Search for Users (V2)" action


Click the "..." on the right hand corner of the Action, then turn on "Pagination" and enter Threshold, e.g. 5000



then you will get the search result over 999 items (if you have)
