# Microsoft Copilot vs Mail App for Outlook

The clearest difference is monetization model: Microsoft Copilot at free with in-app purchases against Mail App for Outlook's subscription. Microsoft Copilot also leads on ratings volume (1.3M vs 6.8K) and update cadence (every 4 days vs every 3 weeks). Mail App for Outlook's advantage is ads (none vs shown). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Microsoft Copilot sells 14 in-app purchases, starting at $1.99 per month and Mail App for Outlook sells 2 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Microsoft Copilot holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Microsoft Copilot has 1.3M ratings behind it against 6.8K, so its average is the more settled of the two. Written reviews complicate that: 29% of Microsoft Copilot's written reviews are positive against 32% of Mail App for Outlook's, so the app with the better star average is not the one people write more warmly about.

Microsoft Copilot ships an update every 4 days, Mail App for Outlook every 3 weeks. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
