Introduction

Manual SSL certificate sharing often requires repeated emails, approvals, permission changes, and file transfers. This becomes difficult to manage when many applications and users are involved.

Using Microsoft Forms and Power Automate, the process can be standardized from request submission to approval, SharePoint access, and certificate delivery.

Key Concept:
Automation reduces manual effort while approval and access controls keep certificate sharing secure and auditable.

---

Business Challenge

The manual process introduced several operational and security challenges:

• Requester details were verified manually.
• Requests did not follow a standard format.
• Approvals and delivery required repeated follow-ups.
• Sensitive files could be shared through uncontrolled channels.
• Tracking request, approval, and delivery history was difficult.

Solution Overview

Microsoft Forms collects the request, Power Automate manages the workflow, SharePoint Online stores the certificate, and Outlook sends notifications.

Component	Purpose
Microsoft Forms	Captures certificate request details.
Power Automate	Manages validation, approval, access, and delivery.
Approval Connector	Sends the request to the Certificate Administrator.
SharePoint Online	Stores certificate files and manages reader access.
Exchange Online / Outlook	Sends certificate, private key, and rejection emails.

Power Automate Workflow Diagram

The flow validates the requester before approval. Approved requests receive the certificate and SharePoint access, while rejected or unauthorized requests are stopped.

When a New Response is Submitted Microsoft Forms Trigger

F Microsoft Forms

Condition 1

Validate Organization Email Domain

True

A Approvals

Start and Wait for an Approval Approval request sent to Certificate Administrator

Condition 2

Check Approval Outcome

True

O Office 365 Outlook

Send an Email (V2) 1 Certificate file and SharePoint path access

O Office 365 Outlook

False

O Office 365 Outlook

Send an Email (V2) Request rejection notification

False

■ Control

Terminate Invalid or unauthorized email domain

Workflow Logic:
A valid corporate email proceeds to approval. Approved requests receive the certificate and private key through separate emails. Rejected or invalid requests do not receive access.

---

Step 1: Certificate Request Form

Users submit requests through Microsoft Forms. The form captures:

• Requester Name
• Email Address
• Application Name

Submitting the form automatically starts the Power Automate flow.

---

Step 2: Organizational Email Validation

Power Automate verifies that the requester belongs to an approved corporate domain.

endsWith(emailAddress,'@company.com')

Security Control:
Requests from non-approved email domains are terminated automatically.

---

Step 3: Approval Workflow

After validation, the Certificate Administrator receives an approval request containing:

• Requester Name
• Email Address
• Application Name
• Request Timestamp

The administrator selects Approve or Reject. No certificate or private key is sent until the request is approved.

---

Step 4: Automated Certificate Distribution

After approval, Power Automate sends two separate emails.

Email 1 – Certificate Delivery

Subject: Certificate Request Approved

Attachments:
certificate.crt
certificate.pem

Body:
Your certificate request has been approved.
SharePoint read access has been granted.

Email 2 – Private Key Delivery

Subject: Private Key File

Attachment:
privatekey.key

Body:
Please find the private key file attached.
This file is confidential and should be stored securely.

Security Best Practice:
Use encryption, password-protected files, restricted access, or secure vault-based storage for stronger protection.

---

Step 5: SharePoint Access Assignment

After approval, Power Automate grants Reader access to the relevant SharePoint library or folder and sends the repository link.

User Approved
      │
      ▼
Power Automate
      │
      ▼
Grant SharePoint Reader Access
      │
      ▼
Send Repository Link

This removes manual permission assignment and ensures access is granted only after approval.

---

Security Design

Control	Purpose
Email Domain Validation	Blocks external or unauthorized requests.
Approval Workflow	Ensures certificate sharing is authorized.
Separate Email Delivery	Reduces exposure of the certificate and private key together.
SharePoint Reader Access	Provides controlled repository access.
Power Automate Run History	Tracks each workflow execution.
Approval History	Records approval and rejection decisions.

Enterprise Recommendation:
Store certificate files and private keys in separate secured repositories and retain request, approval, and access logs.

---

Key Takeaways

• Microsoft Forms provides a standard request portal.
• Power Automate manages validation, approval, and delivery.
• SharePoint provides controlled certificate access.
• Certificate and private key files are delivered separately.
• The solution improves security, efficiency, and auditability.

---

Real-World Outcome:
A manual email-based activity becomes a secure, automated, and auditable SSL certificate sharing process.
