How to Connect Multiple Outlook Accounts to Perplexity
Perplexity’s Outlook connector queries one mailbox, and it cannot send mail yet at all. Carly holds each Outlook identity as a separate connection and exposes them through one custom connector, which covers both the account count and the missing write actions. The same Carly account holds your Gmail inboxes and every calendar on both sides, so you set this up once for all of it.
1. Add your Outlook accounts to Carly
- Sign in at carlyassistant.com.
- Open carlyassistant.com/integrations.
- Find Outlook, click Connect, and authorize the account.
- Click Connect again for the next one, and keep going for as many accounts as you want.
Repeat for every additional mailbox, using a private window if Microsoft preselects the previous login. Verify the full address after each authorization.
Carly connects personal Outlook.com addresses and Microsoft 365 work accounts alike, and each tenant approves independently.
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 Perplexity to reach through the same connector.
2. Add Carly to Perplexity
- Open Settings.
- Go to Connectors.
- Add a custom connector.
- Paste
https://carlyassistant.com/mcp/. - Complete authorization and sign in to the Carly workspace holding the mailboxes.
If your organization manages connectors centrally, an admin may need to allow the connector before it appears.
What Perplexity’s Outlook connector actually does
The Outlook.com connector, last updated July 16, 2026, lets you “query Outlook.com and Outlook on the Web email messages and calendar events directly from Perplexity.” Setup is Settings → Connectors → Outlook.com → Enable, then a Microsoft sign-in and a permission grant.
Perplexity does not publish a per-connector account limit or a second-mailbox setup flow, and the help center never says whether a second authorization is added, rejected, or substituted for the first. Treat the native multi-account behavior as undocumented rather than as a tested promise.
Native Outlook connector versus Carly in Perplexity
| Need | Native Outlook connector | Carly connector |
|---|---|---|
| Query one mailbox | Yes | Yes |
| Hold several mailboxes at once | Undocumented | Yes |
| Compare two mailboxes in one answer | No | Yes |
| Send email | Not yet, stated as future | Yes |
| Create calendar events | Not yet, stated as future | Yes |
| Query more than the primary calendar | No | Yes |
| Run the same routing outside Perplexity | No | Yes |
Carly covers both gaps at once: several mailboxes, and the write actions Perplexity has not shipped for Outlook. Carly offers free Zapier-style workflows; AI agents start at $35/month.
Quick fixes when a mailbox does not appear
| Problem | Fix |
|---|---|
| Connectors are missing entirely | Check your plan; connectors are not on Free |
| An organization mailbox is blocked | Ask your Perplexity admin to approve the connector |
| A second calendar is invisible | Expected natively; route calendar queries through Carly |
| A send request is refused | Expected natively for Outlook; send through Carly |
| Perplexity queries the wrong mailbox | Use the full address and require source attribution |
Frequently asked questions
Can Perplexity send email from Outlook?
Not yet. Perplexity’s help center describes sending email and creating calendar events from Outlook as future functionality, even though the connector requests send permissions at authorization.
How many Outlook accounts can Perplexity connect?
Perplexity does not document a limit or a second-account flow, so treat it as one. Carly makes several mailboxes reachable from one place.
Does the calendar limit apply to a second Outlook account?
The documented limit is one primary calendar per connection, and secondary calendars are not supported. Connect the mailboxes to Carly if you need to see more than one calendar together.

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."
