I can't access latest functionality such as CoPilot in Outlook

Question

Hi,
I've noticed that my Outlook desktop app (both Classic and new) don't have standard CoPilot functionality. I have an Office 365 personal subscription so it comes with CoPilot. CoPilot works as an add-in on Edge, PPT, Word, Excel etc. but not in Outlook

I've tried speaking to multiple support agents, de-installed and re-installed Office 365 but nothing works. At one point it asked me to create an Outlook email alias, which I did.

Since I've done that, when I try to open the Outlook app in my web browser, the only email it lets me see is my Outlook alias. Ironically this shows the full functionality I've been trying to get (includes CoPilot etc.). My desktop app remains unchanged; really out of date functionality e.g. no access to 'To Do' for task management, no CoPilot etc.

I've spent hours trying to fix this but getting nowhere and keep getting passed around from agent to agent for support. Please can someone help?

Hi Matt Ruddock,

This is looking like a pattern that typically occurs when desktop Outlook is added using a different identity or mailbox type than the one that supports the full Outlook.com (Exchange) experience.

In many cases, re‑adding the account using the exact @outlook.com alias (the same one that works on Outlook on the web) helps ensure Outlook provisions the mailbox as Outlook.com/Exchange. This is also the connection type required for newer integrations like Copilot and Microsoft To Do.

New Outlook for Windows

1. Settings (gear) > Accounts
2. Remove the account that’s missing Copilot
3. Add the account again, signing in with your exact @outlook.com alias

The account is provisioned as Outlook.com/Exchange and feature availability aligns with Outlook on the web.

Classic Outlook (Legacy)

1. Close Outlook
2. Control Panel > Mail > Show Profiles > Add… (create a new profile)
3. Add the account using the @outlook.com alias (not the older sign‑in address)
4. Open Outlook using the new profile

In File > Account Settings, the account Type should show Exchange / Outlook.com (wording may vary). If it still shows IMAP or POP, remove and re‑add the account using the alias so it connects as Exchange.

Note: Creating a new profile or removing/re‑adding an account may temporarily remove locally cached mail until it fully re‑syncs from the server.

• Copilot is missing, disabled, or doesn't work correctly
• Add or remove an email alias in Outlook.com

Next step (to confirm)

• In Classic Outlook > File > Account Settings, what is the account Type (Exchange vs IMAP/POP)?
• In Word > File > Account, which signed‑in address is shown (alias vs original sign‑in)?

Please let me know if this proves useful to you, or if you would like further assistance.

I'm looking forward to your reply.

Copilot in Outlook depends on both the correct license and the right Outlook/Office configuration. Based on the symptoms, the web experience is using the correct, Copilot‑enabled account, while the desktop apps are either using the wrong account, the wrong update channel, or blocked by privacy/settings.

Use the following checks and fixes in this order on the desktop apps:

1. Confirm the correct Copilot‑licensed account is primary in Outlook/Office
   • In any Microsoft 365 desktop app (Word, Excel, or Outlook), go to File > Account.
   • Under User Information, make sure the account shown at the top is the one with the Microsoft 365 Personal subscription that includes Copilot.
   • If another account is listed as primary, sign out of all accounts in that app, then sign back in with the Copilot‑licensed account and make that the primary account.
   • For Copilot to appear in new/unsaved or local files, the current primary account must be licensed for Copilot.
2. Refresh the Office/Copilot license on Windows
   • In any Microsoft 365 app, go to File > Account.
   • Select Update License.
   • Close all Microsoft 365 apps (including Outlook) and reopen them so the license refresh takes effect.
3. Ensure the desktop apps are fully updated
   • Still in File > Account, under Product Information, use Update Options > Update Now to install the latest build.
   • Copilot features require current builds; outdated Office installations may not show Copilot in Outlook even if the license is valid.
4. Check the update channel (for business scenarios)
   • In File > Account, under Product Information, check the update channel text.
   • If it shows Semi-Annual Enterprise Channel, Copilot features will not be available in the desktop apps.
   • In that case, the device must be moved to Current Channel or Monthly Enterprise Channel. For managed/business devices, this requires help from the organization’s IT/admin. While waiting, Copilot will continue to work in the web apps.
5. Verify privacy and connected experiences settings (desktop)
   • In any Microsoft 365 app on Windows:
     1. Go to File > Account.
     2. Under Account Privacy, select Manage Settings.
     3. Turn on Experiences that analyze your content.
     4. Scroll down and turn on All connected experiences.
   • If these are off, Copilot can be hidden or disabled in the desktop apps even when it works on the web.
6. If using Mac for Outlook desktop (for completeness)
   • In a Mac app (Word/PowerPoint):
     1. Select the app name menu (for example, Word) at the top of the screen.
     2. Select About <app name> > More Info… > Refresh License.
     3. Close all Office apps and reopen them.
   • Then in Word > Preferences > Privacy, ensure Experiences that analyze your content and All connected experiences are turned on.
7. If Copilot is still missing or disabled in Outlook desktop
   • The following conditions can also prevent Copilot from appearing or working correctly in Microsoft 365 Apps:
     • Recently assigned Copilot license that has not fully propagated yet.
     • Conflicting sign‑ins (for example, signed in with both a personal and a work/school account) causing Copilot license validation issues.
     • Device‑based licensing or Shared Computer Activation (Copilot requires a user‑based license and is not supported with SCA).
     • Network issues that block Copilot endpoints.
   • If any of these apply (especially mixed accounts or device‑based licensing), adjust the configuration so the Outlook desktop app runs under the single, Copilot‑licensed personal account.
8. Use Outlook’s built‑in Copilot chat (when available)
   • In classic Outlook for Windows, once Copilot is enabled, a Copilot icon appears in the left app bar. Selecting it opens Copilot chat directly in Outlook, where it can summarize emails, find @mentions, and generate content.

If, after confirming the correct primary account, refreshing the license, updating Office, enabling privacy/connected experiences, and ensuring a supported update channel, Copilot still does not appear in Outlook desktop while working in the web app, the remaining step is escalation through Microsoft support with explicit mention that Copilot works on the web but not in desktop apps under the same Copilot‑licensed account. This aligns with known cases where backend or licensing propagation issues required intervention from Microsoft engineering.
