Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Microsoft Copilot ships an update every 4 days, Mail App for Outlook every 3 weeks. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
