Copilot in Outlook With Voting Buttons: Result Tabulation Walkthrough

You need to tally votes sent through Outlook voting buttons but copying each reply into a spreadsheet takes too long. Copilot can automate this tabulation by reading the voting data stored in each email message. This article explains how Copilot interprets voting button responses and walks through the exact steps to generate a result summary. You will learn how to prompt Copilot correctly and what to do when it returns incomplete counts.

How Outlook Voting Buttons Store Responses and Why Copilot Can Read Them

When you send an email with voting buttons in Outlook, the message includes a custom property called VotingResponse. Each recipient who clicks a button sends back a reply that contains this property with the chosen option. The reply is a standard email message with a specific header field that Outlook and Exchange Online recognize.

Copilot for Microsoft 365 can access these header fields through its integration with Microsoft Graph. It queries the VotingResponse property on replies to the original poll message. Copilot then aggregates the values and presents them in a simple count or table format. This works only if the original message was sent from a Microsoft 365 mailbox and the replies are stored in the same mailbox.

The key prerequisite is that Copilot must have permission to read the mailbox items. Your Microsoft 365 admin must have enabled Copilot for your account and granted the required Graph permissions. Without these, Copilot cannot access the voting data and will return a message saying it cannot find the information.

Steps to Generate a Voting Result Summary With Copilot

1. Open the original poll message in Outlook
   Navigate to your Sent Items folder and double-click the email that contains the voting buttons. The message must be the one you originally sent, not a reply. Copilot needs the original message ID to locate the related replies.
2. Open the Copilot pane in Outlook
   Click the Copilot icon in the top ribbon or press Alt+I to open the Copilot pane on the right side of the window. Ensure the pane is docked and ready to accept input.
3. Enter the tabulation prompt
   In the Copilot chat box, type: Tally the voting button responses from the last poll I sent. Press Enter. Copilot will process the request and display a count of each voting option. If you have multiple polls, specify the subject line: Tally the voting responses for the email with subject “Team Lunch Poll”.
4. Review the tabulated results
   Copilot returns a numbered or bulleted list showing each option and the number of votes. For example: Option A – 5 votes, Option B – 3 votes, Option C – 2 votes. No formatting is applied. You can copy the text into a document or spreadsheet.
5. Refresh if results are missing
   If the initial response says “I couldn’t find any voting responses,” click the Refresh button in the Copilot pane title bar. This forces a new scan of the mailbox. Wait 10 seconds and repeat the prompt. New replies that arrived after the original scan will now be included.
6. Ask for a detailed breakdown
   For a per-recipient list, prompt: Show me who voted for each option in the poll. Copilot will list each respondent’s name and their selected option. This works only if the replies are from internal recipients whose names are in your organization’s directory.

Common Issues When Tabulating Voting Button Results

Copilot returns zero votes even though replies exist

This happens when the original poll message was sent from a shared mailbox or a delegate account. Copilot checks the mailbox of the sender. If the message was sent from a shared mailbox that Copilot cannot access, it finds no replies. Open the original message from your own Sent Items folder. If the message was sent by a delegate, switch to that delegate’s mailbox and run the prompt there.

Copilot shows partial counts or misses recent replies

Copilot caches mailbox data. It may not include replies that arrived in the last few minutes. Use the Refresh button in the Copilot pane and then repeat the prompt. If the problem persists, close and reopen Outlook to force a full sync.

Copilot says it cannot access voting data

This indicates a permissions issue. Contact your Microsoft 365 admin and verify that Copilot is enabled for your account and that the Mail.Read and Mail.ReadBasic Graph permissions are granted. The admin can check this in the Microsoft 365 admin center under Settings > Org settings > Copilot.

Copilot returns results for a different poll

If you have multiple voting polls in your Sent Items, Copilot may pick the wrong one. Always include the exact subject line in your prompt. For example: Tally the voting responses for the email with subject “Q3 Meeting Time Poll”. This narrows the search to a single message.

Copilot Tabulation vs Manual Tabulation: Key Differences

Item	Copilot Tabulation	Manual Tabulation
Time required	30 seconds per poll	5 to 15 minutes depending on response count
Accuracy	Reads header data directly, no human error	Prone to miscounts when scanning replies manually
Recipient names	Shows names only for internal recipients	Shows all names from From field
Export format	Plain text in Copilot pane	Can be typed into Excel or a table
Requires internet	Yes, Copilot needs a connection to Microsoft Graph	No, works fully offline

Copilot tabulation is faster and less error-prone for polls with more than 10 respondents. Manual tabulation gives you full control over formatting and works offline. Choose Copilot when speed matters and manual when you need to include external recipients.

You can now use Copilot to tally voting button responses in Outlook without leaving your inbox. Start by selecting the original poll message and opening the Copilot pane. For advanced analysis, prompt Copilot to show a per-recipient breakdown or export the results to a Word document using the Copy button in the Copilot pane.
