Velocity - Microsoft o365 Oauth - Could not login using EWS credentials provided

• Follow the Microsoft Room Scheduling PDF step by step
  • Find it on any Velocity SKU resource page or use the link below
  • Integration Note for Microsoft Room Scheduling - Pages 6-8 cover OAuth setup
• Velocity gateway needs internet access (green globe in top left)
• Admin rights in Velocity
• Admin rights in O365
• Important: Client secret expires after 2 years - set a reminder at 1 year 11 months to create a new one

Microsoft only tells us if everything works or doesn't - one incorrect setting triggers this error. Here's what to check:

Quick Checklist:

1. Client Secret: Check if expired (2-year limit)
2. Admin Email: Must match Azure exactly
3. Manifest: Verify correct format
4. API Permissions: Look for green checkmark
5. Resource Mailbox: Confirm delegation setup
6. Internet Access: Check for green globe

Use the same email that created your Azure account - this email created the secret value and needs matching credentials.

Common Mistakes:

• Using a different email than your Azure registration
• Using a personal email instead of admin account
• Mixing up admin email with resource room email

The manifest setup is critical - one missing character can cause issues. Follow these steps carefully:

Setup Tips:

• Copy Exactly: Use the format below - no changes
• Check Carefully: All brackets { } and commas must be present
• Keep Original: Don't change any IDs or values
• Adding Content: If content exists, add comma after last }

"requiredResourceAccess": [
    {
        "resourceAppId": "00000002-0000-0ff1-ce00-000000000000",
        "resourceAccess": [
            {
                "id": "dc890d15-9560-4a4c-9b7f-a736ec74ec40",
                "type": "Role"
            }
        ]
    },
    {
        "resourceAppId": "00000003-0000-0000-c000-000000000000",
        "resourceAccess": [
            {
                "id": "e1fe6dd8-ba31-4d61-89e7-88639da4683d",
                "type": "Scope"
            }
        ]
    }
],

After manifest setup, an admin must grant permissions. Look for the green checkmark to confirm success.

Key Points:

• Admin Required: Only admins can grant permissions
• Be Patient: Changes take a few minutes to apply
• No Checkmark? Try refreshing your browser
• Still No Access? Log in or contact your Azure Admin

Start with a test room - group policies can affect access. Microsoft offers several delegation methods.

Setup Steps:

• Test First: Create new room without permissions
• Be Patient: Wait 10-15 minutes after changes
• Double Check: Verify in both Exchange Admin Center and Azure Portal
• Access Rights: Admin needs full mailbox access
• Configuration: Confirm room mailbox settings
