Office 365 Groups Checking First to See user is not in group

[daniellemaree]

Hi

I have a flow I have built and it users can request to join departments. The flow uses the O365 Connector tool to add the user to the 0365 group. 

However to dumb proof the flow if a user is already in the group and requesting it again, the flow errors as the user is already  in the O365 group.  "One or more added object references already exist for the following modified properties: 'members'.","

Is there a way from the action causing the error and to simply reject the user from the request?

Or is it possible to get the flow to check first if the user is in the group? If so how can this be done

Hi @daniellemaree,

The function to check if the user is in the group is not supported in microsoft flow currently.

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

Also there is no any way from the action causing the error and to simply reject the user from the request in microsoft flow currently.

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

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
