Re: Flow approvals with a Approved, Partial & Reject
Hi @felix_flow,
How do you create your approval email? With "Start an approval" action?
Do you want to create an approval email which has 3 options?
I think the "Send email with options" action of Office 365 Outlook connector could achieve your needs. I have made a test on my side and please take a try with the following workaround:
User Options field set to following formula:
"Fully" Approved, Partial (see comments), Rejected
The flow works successfully as below:

In addition, sending approval email which contains 3 options using "Start an approval" action is not supported in Microsoft Flow currently, if you would like this feature to be added in Microsoft Flow, please submit an idea to Flow Ideas Forum:

More details about the "Send an email with options" action, please check the following article:
