Checking Outlook Distribution List members

[addy2019]

I'm trying to create a flow which will send the Approval request if the user doesn't exist in Outlook Distribution List. I couldn't find any step in Flow or feature in Powerapps which could pull member list from Distribution list.

Can anyone help

You have to execute a MS GRAPH request to do that. Visit Graph Explorer and play a bit.

Thanks. I see an Api which gives required information but which flow action can be used to use this Api. I see Microsoft Graph Action but it has limited options.

[VictorIvanidze]

Use the "Send an HTTP request (Preview)" action from the "Office 365 groups" connector.

"Send an HTTP request (Preview)" step timing out. I cancelled it after 10 retries.

[VictorIvanidze]

Can you reproduce it in Graph explorer?

If not - please show your action.

[addy2019]

Yes API is working in Graph Explorer

[VictorIvanidze]

Check if any GRAPH request is working in your flow with "Send an HTTP request (Preview)" action.

[addy2019]

"https://graph.microsoft.com/v1.0/me/" this Api is working in  "Send an HTTP request (Preview)" action while this one is timing out in Action "https://graph.microsoft.com/v1.0/groups/{group-id}/members?$count=true"

[VictorIvanidze]

Add / before ?

 https://graph.microsoft.com/v1.0/groups/{group-id}/members/?$count=true

[addy2019]

No difference again timed out

[VictorIvanidze]

Try to remove ?$count

Will it work then?

Also, how many members in the group?

[addy2019]

yes tried with /members/ as well but no luck.

There are 85 members

[VictorIvanidze]

Try to create a new DL with 10 members and test.

[addy2019]

I'm not an admin, only IT can create a DL. Also why do you think having only 10 members would work. Do you think having 85 members is timing it out?

[VictorIvanidze]

I do not know. All my DLs contain not more than 20 members. The GRAPH requests have no timeouts.

[addy2019]

i don't think number of member is responsible for Timeout. Its something else but not sure what that is.
