How to Connect Multiple Gmail Accounts to ChatGPT Work
Yes. ChatGPT Work connects several Gmail accounts natively. OpenAI shipped it on August 28, 2026 for Gmail, Google Calendar and Google Contacts, and Work uses the same plugins, so one task can read personal and work Gmail together. Open Settings > Plugins, select Gmail, and choose Connect another account.
Work’s real limits are Outlook and what starts a task. Add the Carly plugin and every Gmail and Outlook account, personal and work, answers the same Work task.
1. Add the next Gmail account
- Open Settings > Plugins.
- Select Gmail.
- Under Connected accounts, select Connect another account.
- Sign in to the next Google account and approve the permissions.
- Repeat for every Google account.
A Google Workspace account may need its administrator’s approval. On a Business or Enterprise workspace, a ChatGPT admin may also need to enable the app or approve the account’s domain.
2. Ask Work across all of them
Once the accounts are attached, just ask:
Check all my email for anything about the Q4 renewal in the last 30 days and draft a summary for Michael.
Go through all my inboxes and tell me what still needs a reply today.
Work can also run a task when a new Gmail message arrives. OpenAI documents these event-triggered tasks on Plus, Pro, Business, Enterprise and Edu, created on the web or mobile, and Enterprise and Edu admins have to switch on Allow event-triggered scheduled tasks first.
Where Work stops
OpenAI's multi-account support started with Gmail, Google Calendar and Google Contacts in August 2026 and spread to more plugins on September 17, 2026, though the help center still says only that "some apps support more than one connected account." Its Outlook article hedges a second Microsoft account with "where supported," routes some actions through each company's Microsoft Entra administrator, and never mentions Outlook.com or Hotmail. Carly carries every Gmail and Outlook account you have, personal and work, at once.
Three more things a Work task runs into:
- Outlook mail doesn’t start a task. Work’s documented triggers are new Gmail messages, Slack channel messages and GitHub pull request activity. Since September 29, 2026, “supported plugins can use MCP events,” but OpenAI lists no Outlook event.
- Admins decide the Microsoft side. On Business and Enterprise, a workspace admin enables each Outlook action and “may restrict connections to Outlook accounts from an approved set of domains.” A consultant working inside a client’s Microsoft 365 hits that wall first.
- Scheduled sends are failing for some users. Since September 30, 2026, users on OpenAI’s forum report that scheduled tasks are blocked at the Gmail send step with “This tool call was blocked by OpenAI’s safety checks,” while the same send works by hand in a chat.
3. Connect Carly for Outlook and Hotmail
- Sign in at carlyassistant.com.
- Open carlyassistant.com/integrations.
- Connect each Gmail and Workspace account, then each Outlook account: Outlook.com, Hotmail and Live, plus Microsoft 365 at every company you work with.
- In ChatGPT, click Get the Carly plugin, install it, and sign in to your Carly account.
One Work task can then search personal Gmail and a client’s Outlook together, brief you across every inbox, and send from the right address with attachments. It sees every Google and Outlook calendar too, so Work can find a time or share a booking page. Carly connects to thousands of apps, so the CRM and the shared drive come along.
Carly also keeps working after the task ends. Workflows start on their own within minutes when mail lands in any account, Gmail or Outlook, and AI agents get their own email address that clients can write to directly.

Quick fixes when an account does not appear

| Carly does not appear in Plugins | Search for Carly by name; if installation is unavailable, ask the workspace admin to enable it |
Frequently asked questions
Can ChatGPT Work natively connect two Gmail accounts?
Yes, since August 28, 2026. Open Settings, then Plugins, select Gmail and choose Connect another account. Google Calendar and Google Contacts got the same treatment.
Can I use personal Gmail and Google Workspace together?
Yes, natively. A company-managed ChatGPT workspace can limit which account domains you connect, so check with the admin if a personal address will not attach.
Can a Work task search Gmail and Outlook together?
Yes, as two plugins, as long as Outlook connects. OpenAI’s Outlook documentation never mentions personal Outlook.com or Hotmail addresses. Connect both providers to Carly and one task covers them.
Can ChatGPT Work start a task when Outlook mail arrives?
Not per OpenAI’s documentation, which lists Gmail, Slack and GitHub events. Carly workflows start within minutes of mail arriving in any Gmail or Outlook account.

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."
