Connect Multiple Email Accounts to Grok Bot
Carly connects every mailbox you own, Gmail and Outlook together, and one Grok Bot conversation works across all of them. Grok Bot reaches mail through Cursor’s plugins, and each one signs in a single identity: one Google account in the Gmail plugin, one Microsoft account in the Outlook plugin that landed on Aug 27, 2026. Anything past that is a browser session, and every one of those logins is account-wide, on a single shared computer that all of your Bots can drive. Connect each mailbox to Carly instead and every account stays its own addressable identity, so one Grok Bot conversation can work in whichever inbox you name.
1. Add your Gmail and Outlook mailboxes to Carly
- Sign in at carlyassistant.com.
- Open carlyassistant.com/integrations.
- Find Gmail and Outlook, click Connect, and authorize the mailbox.
- Click Connect again for the next one, and keep going for as many mailboxes as you want.
Mix providers freely. A second Gmail sits beside the first, and Outlook sits beside both.
Two provider quirks are worth knowing before you start. Google preselects your current login, so choose Use another account rather than the suggested profile. Microsoft is stickier still and will silently reuse whichever account the browser already holds, so sign out of the Microsoft session between accounts or use a separate browser profile. A managed Google Workspace or Microsoft 365 tenant may also route consent to an administrator, which is policy rather than a failure and is worth resolving before you connect the rest.
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 Grok Bot to reach through the same connector.
2. Add Carly to Grok Bot
- Find Plugins on the Grok Bot sidebar, or under Settings, which also opens with Cmd or Ctrl plus comma. On the mobile app, tap your avatar at the top left and select Plugins.
- Add Carly’s remote MCP server,
https://carlyassistant.com/mcp/. - Finish the authorization in the browser tab that opens.
- Sign in to the Carly account holding the mailboxes you connected above.
- Confirm Carly appears under Installed.
Cursor and xAI describe the same screen from two directions, which is why it is worth checking both places. Cursor’s guide says to “select Plugins on the sidebar, or follow an in-chat Connect card,” while xAI’s docs say connectors “are shown as Plugins in the current app” and route you through Settings → Plugins.
Grok Bot takes remote MCP servers rather than local ones, and Carly’s is hosted, so it qualifies. One thing can stop you outright: Grok Bot runs on your Cursor account, and Cursor’s MCP policy lets a team admin decide whether members may configure their own MCP servers at all. If your plugin list is locked to the marketplace, that setting is the reason, and an admin has to change it.
What one chat can do afterwards
- Search a personal Gmail and a work Outlook in the same question.
- Compare a thread in one company’s mailbox against another’s.
- Produce a morning briefing grouped by inbox.
- Draft or send from the exact address you choose.
- Label, move, flag, or archive in the correct account.
- Check several calendars for conflicts while writing to only one.
Nothing is merged. Each mailbox keeps its own credentials and stays individually addressable, so an instruction that names Client cannot quietly land in your work account.
Keep Require Approval on anything that sends
- Open the Bot’s approval rules.
- Add a Require Approval rule for sending external email.
- Extend it to moves, deletions, and calendar changes.
Reads and searches then run freely while a send from a client tenant stops in front of you. An approval covers the proposed action only and does not reverse work already done, so the rule belongs in place before the first real task.
One account per plugin, one shared set of logins
Gmail arrives through Cursor’s Gmail plugin, which takes more than one Google account by design: its page has an Add Another Account control, and Cursor staff pointed a user at it on Aug 28, 2026. Getting Google to authorize any of it is the live problem. Google plugins have authenticated locally and failed in the cloud since Aug 4, which matters because the cloud is the only environment a Bot runs in, a second account was reported on Aug 14 to revert to Authorize seconds after it appears to land, and on Aug 28 users started hitting a flat refusal from Google: “This app is blocked. The app tried to access sensitive info in your Google Account.” The workaround staff gave is telling. Authorize Gmail from Cursor instead, because that path still works and the connection is shared with Grok Bot.
Outlook arrived separately, in the first-party Outlook, Outlook Calendar, and OneDrive plugins added on Aug 27, 2026, and the mail one signs in a single Microsoft account. It had not surfaced in the public marketplace listing the next day, so it may not be in your Plugins screen yet. Whatever does connect is account-wide, shared by every Bot you run.
The one case where the shared browser holds up
If every mailbox is yours personally, carries no client data, and you run exactly one Bot, signing into the shared browser will get you through a read-only question today. Know what you are accepting first. Users who signed Microsoft into the agent computer before the Outlook plugin existed reported being logged out of Microsoft on their own machines, agents that lost the session repeatedly while skimming mail, and in one case a Microsoft 365 account locked outright after the same credentials appeared on a server and a PC at once, which is exactly what a tenant security policy is built to catch. Then there is the second Bot. The moment you add one, or hand work to a teammate, or a client tenant lands in the mix, every cookie on that machine is already in scope, and there is no per-account setting to walk it back.
The shared browser next to Carly
| Need | Grok Bot’s plugin or shared browser | Carly plugin |
|---|---|---|
| Reach one mailbox | Yes | Yes |
| Hold several Gmail accounts | Labelled slots exist, the second is reported not to stick | Yes |
| Reach Outlook at all | Yes, one Microsoft account per plugin | Yes |
| Give each account its own permissions | No, logins are account-wide behind one tool list | Yes, each is its own connection |
| Stop one Bot from reaching a client inbox | No, xAI rules this out explicitly | Yes, per connected account |
| Send from a named address | Whichever session the browser is in | Yes, with that account’s permissions |
| Say which account it acted in | Not reliably | On every action |
| Survive a handoff to another Bot | The next Bot inherits every login | Yes, routing stays by address |
Carly gives Grok Bot one account-aware toolset where the accounts stay apart, and Carly’s agents carry their own name, address, and memory, so a client can write to one directly and the work starts on arrival. Free Zapier-style workflows; AI agents from $35/month. Connect every inbox at carlyassistant.com.
Quick fixes
| Problem | Fix |
|---|---|
| A Bot acted in the wrong inbox | Name the full address in the instruction rather than the role |
| Two Bots need different access | Route through Carly, which holds all of them and keeps each separate |
| The provider reused your signed-in account | Choose Use another account, or sign out of Microsoft between connections |
| A work account stalls at consent | A Workspace or Microsoft 365 administrator has to approve before authorization completes |
| Plugins will not let you add a server | Your Cursor team admin controls whether members may add their own MCP servers |
| Sends go out before you see them | Add a Require Approval rule for external email |
Frequently asked questions
Can Grok Bot connect to multiple email accounts?
By design, yes. Gmail comes through Cursor’s Gmail plugin, which takes further Google accounts through an Add Another Account control, and Outlook through the plugin added on Aug 27, 2026, which signs in one Microsoft account. Whether authorization completes is the open question: Google blocked the Grok Bot connection outright for users on Aug 28, and a second Gmail account was reported reverting on Aug 14. Every one of those logins belongs to your account rather than to one Bot, so the mailboxes are reachable but not separable. Connecting each one to Carly is what makes them individually addressable.
Do separate Bots keep my inboxes apart?
No. xAI states that browser cookies, signed-in sessions, files, and command-line credentials are shared across every Bot on your account, and that the separate screens are not separate security boundaries.
Can I mix Gmail and Outlook?
Yes. Connect every identity to Carly, on either provider, and one request covers all of them.
Does connecting Carly give every Bot access?
Installed connectors in Grok Bot are account-wide, so plan access at the account level. What changes is that each mailbox inside Carly is a distinct authorized connection, so instructions name a target address instead of inheriting whatever the browser happens to be signed in to.
Will my admin need to approve anything?
Possibly twice. A managed Google Workspace or Microsoft 365 tenant may require administrator consent for the mailbox connection, and a Cursor team admin controls whether you may add your own MCP server to Grok Bot.

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."
