How to Connect Multiple Gmail Accounts to Copilot
Microsoft Copilot reads Gmail but documents no multi-account setup. Consumer Copilot at copilot.com has a Gmail connector that searches mail, calendar, and contacts. Microsoft 365 Copilot, the paid work product, has no Gmail connector at all. Neither one documents a way to hold two Gmail accounts at the same time. Carly connects each Gmail account separately and keeps them all reachable, so a question that spans two inboxes has somewhere to go. The same Carly account holds your Outlook mailboxes and every calendar on both sides, so you set this up once for all of it.
1. Add your Gmail accounts to Carly
- Sign in at carlyassistant.com.
- Open carlyassistant.com/integrations.
- Find Gmail, click Connect, and authorize the account.
- Click Connect again for the next one, and keep going for as many accounts as you want.
There is no forwarding, no POP import, and no mailbox merge. Each account stays its own connection, which is what makes routing possible.
If Google Workspace shows an administrator review message, ask the Workspace administrator to approve the connection and repeat the authorization.
Carly connects to thousands of apps, so while you are on that page you can add your calendars, files, CRM, and anything else you want Copilot to reach through the same connector.
2. Choose how Copilot reaches Carly
Copilot has no box where an ordinary user pastes a connector URL, on either SKU. There are three honest routes, and which one applies depends on who you are in your tenant.
You work with Carly directly. Carly runs the multi-account mail and calendar work on its own, and the accounts you connected in step 2 are immediately usable there. Most readers stop here.
A maker adds Carly in Copilot Studio. This is the Microsoft-side route that actually fits Carly, because it carries write actions. Tools → Add a tool → New tool → Model Context Protocol, then fill in server name, description, and https://carlyassistant.com/mcp/ as the server URL, choosing None, API key, or OAuth 2.0 for auth. Only Streamable transport is supported; SSE was dropped in August 2025. It needs a work or school account and a paid licence, the trial cannot publish the agent, and what you get is a separate agent rather than Copilot Chat.
An administrator adds a federated connector, which is a partial fit. In the Microsoft 365 admin center, go to Copilot → Connectors → Gallery → Create a new connector, then under Connect to MCP server select Add and fill in the display name and Base URL. This needs the Global Administrator or AI Administrator role plus a registered Entra SSO or OAuth 2.0 application. Microsoft requires federated connectors to expose read-only tools, so an admin taking this route gets a read slice rather than drafting, sending, or labelling. Federated connectors reached general availability in June 2026 and admin center management shipped in July 2026.
If none of those shapes fits your team, the API and bring-your-own-key path runs through the Carly team at carlyassistant.com/book/carly-team/meeting.
One trap worth knowing before you try to build this yourself with Power Platform. The Gmail connector there is restricted precisely for free accounts: customers using consumer Gmail addresses ending in @gmail.com or @googlemail.com “can only connect to a limited set of services,” while “customers using Google Workspace accounts are not impacted by this change.” A flow built against a non-compliant service saves in a disabled state.
Which Copilot you have decides everything
The two products share a name and almost nothing else here.
| Consumer Copilot (copilot.com) | Microsoft 365 Copilot | |
|---|---|---|
| Gmail connector | Yes | No Gmail connector exists |
| What it does with Gmail | Search and read mail, calendar, contacts | Not applicable |
| Send or modify Gmail | Not documented | Not applicable |
| Google apps available | Drive, Gmail, Calendar, Contacts | Drive, Calendar, Contacts. Gmail absent |
| Surfaces | copilot.com and Copilot Mobile | Microsoft 365 apps and Copilot Chat |
Microsoft’s connector documentation describes one Connect action per service, and the authorization step covers “selecting which account you want to use.” The one place it says “as many as you want” is about different services, not several accounts of one service. Nothing in Microsoft’s documentation either permits or forbids a second Gmail connection, so treat it as undocumented rather than blocked.
Microsoft ships something called multiple account access, and it is real. If your employer turns it on, you can use a personal Copilot subscription at work. What it bridges is licensing: it lets a Copilot license attached to one account work on the document currently open in front of you from another account. The same documentation still answers No to reaching your organization’s Microsoft Graph and No to questions about any document other than the open one. The cross-mailbox gap is unchanged, so do not read the feature name as multi-inbox support.

Quick fixes when an account will not appear
| Problem | Fix |
|---|---|
| Copilot returns nothing from OneDrive or Outlook | Sign in with the same Microsoft account that owns that content |
| Work content missing on the work side | Ask whether your admin enabled that connector and whether you hold a Copilot license |
| Google connected the same address twice in Carly | Remove the duplicate and reconnect with Use another account |
| Workspace blocks the Carly connection | Ask the Workspace administrator to approve it |
| Federated connector added but invisible | New Microsoft-published connectors sit in a seven day admin review window |
| Power Automate flow saved disabled | The consumer Gmail restriction applies; use a Workspace account or your own Google OAuth app |
Frequently asked questions
Can Microsoft Copilot connect two Gmail accounts?
Microsoft does not document a way to do it. The consumer connector authorizes one Google account, and the work product has no Gmail connector at all. Connecting each account to Carly keeps several Gmail identities reachable from one place.
Does Microsoft 365 Copilot read Gmail?
Not through any Microsoft-built connector. Google Drive, Calendar, and Contacts are in the gallery; Gmail is not. A partner connector indexes Gmail for search and is licensed separately from Microsoft.
Can I paste a connector URL into Copilot myself?
Copilot exposes no paste-a-URL box to ordinary users on either SKU. An administrator can add an MCP Base URL in the Microsoft 365 admin center, though those connectors are read-only, and a maker can add one in Copilot Studio, which is the route that carries write actions.
Does Copilot send email from Gmail?
Microsoft documents the consumer Gmail connector as search and read. No send action is documented, and federated connectors on the work side are read-only by design.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
