Office 365 Groups - Check If Member Exists Before Adding



Is it possible to check whether a user exists in an O365 Group  prior to adding to an O365 Group?


Is there somehow the information can be validated in the flow? If so could you explain how this can be achieved?

Hi @daniellemaree,


The function to check if a user exists in an O365 Group is not supported in microsoft flow currently.

I afraid that there is no way to achieve your needs in Microsoft Flow currently.


If you would like this feature to be added in Microsoft Flow, please submit an idea to Flow Ideas Forum:


Best regards,

I wanted to add users to a group based on entries in a sharepoint list.

I solved it the following way:


  1. Trigger: when an item is created or modified
  2. Action: Initialize a string variable "GroupMembers"
  3. Action: "list group members"
  4. Apply to each "value" from previous step
    1. Action: "Append to string variable"
      1. Name = variable you created in step 2
      2. Value = mail;
  5. Add condition
    1. if "GroupMembers" does not contain "email-value from sharepoint list item"
    2. If yes. Add member to group action
    3. If no, empty



Thanks - very useful indeed

Thank you for the simple solution!
