Question details

Users are experiencing issues where Microsoft Forms response invitations are reported as sent but are not delivered to recipients, or the emails are missing from the Outlook Sent Items folder.

How to Fix Microsoft Forms Invitation Emails Not Delivered

Product: Microsoft Forms / Outlook
Device & OS: not provided
Scenario: Sending response invitations to users via email directly from Microsoft Forms.
Observed behavior: The Forms interface indicates the invitation was successfully sent, but the email fails to arrive at domains like AOL, or the outgoing message does not appear in the sender's Outlook Sent Items.

Before you start

Verify that you are signed into both Microsoft Forms and Outlook on the web using the exact same Microsoft account, and ask the recipient to check their Junk or Spam folders.

Solution 1Recommended

Add and Set a New Primary Outlook Alias

Changing your primary account alias can resolve email domain routing issues that prevent Microsoft Forms invitations from sending correctly.

Sometimes, the original domain of your Microsoft account may encounter routing issues when sending automated emails. Creating a new Outlook.com alias and setting it as the primary address can force the system to use proper Exchange sending routes.

Sign into your Microsoft Account

Go to the Microsoft account management website and sign in with your current credentials.

Navigate to Account Info

Go to the 'Your info' tab and select 'Edit account info' or 'Sign-in preferences'.

Add a new alias

Click 'Add email' to create a new Outlook.com alias for your account.

Set as primary

Click 'Make primary' next to the newly created alias, then sign out and sign back into Microsoft Forms and Outlook to resend the invitation.

Alias Update: It may take a few minutes for the new primary alias to sync across all Microsoft 365 services.

Solution 2

Verify Sending via Outlook on the Web

Using the web version of Outlook helps you bypass desktop application syncing errors or IMAP login issues.

Frequently Asked Questions

Why are my Microsoft Forms emails not showing in Outlook Sent Items?

This usually happens if the account used to create and send the form is not properly synced with your primary Outlook mailbox, or if you are sending from an alias that has not been configured as your primary address.

Why do AOL email addresses block Microsoft Forms invitations?

AOL and similar email providers may aggressively filter automated emails from Microsoft Forms as spam. Instruct your recipients to check their junk folders, or ask them to add the Microsoft sender address to their safe senders list.

Can I manage Forms invitations from the Outlook desktop app?

Yes. You can add your Microsoft account to the Outlook desktop application by navigating to File > Add Account. This ensures your invitations sync properly with your local Sent Items folder.
