Connect Multiple OneDrive Accounts to Perplexity
Perplexity’s Microsoft 365 connector holds one Microsoft work identity, documents no consumer-account path for files, and is desktop-browser only, so a work drive and a personal drive in one chat runs through Carly. Authorize each Microsoft identity in Carly, add Carly to Perplexity once, and name the drive you mean. Carly holds your Google Drive accounts, and every mailbox and calendar on both sides, in the same place.
1. Add your OneDrive accounts to Carly
- Sign in at carlyassistant.com.
- Open carlyassistant.com/integrations.
- Find OneDrive, click Connect, and authorize the account.
- Click Connect again for the next one, and keep going for as many accounts as you want.
Consumer accounts and work tenants connect the same way here, and each tenant approves independently, so one administrator declining does not block the others.
Carly connects to thousands of apps, so while you are on that page you can add your inboxes, calendars, CRM, and anything else you want Perplexity to reach through the same connector.
2. Add Carly as a custom remote connector
Perplexity shipped Bring Your Own Connector for Pro, Max and Enterprise subscribers in March 2026, which is how Perplexity reaches the drives you just authorized:
- Open Settings → Connectors.
- Select + Custom connector.
- Choose Remote.
- Enter a name and
https://carlyassistant.com/mcp/as the MCP server URL. - Choose the authentication option and acknowledge the third-party connector risk.
- Add the connector and finish authorization.
Perplexity’s remote connector guide supports HTTPS servers over Streamable HTTP or SSE. Enterprise administrators can share a connector across the organization and decide whether members may add their own; that member permission is disabled by default.
What one chat can do afterwards
- Search a work OneDrive and a personal OneDrive in the same question.
- Say which account each copy of a document lives in.
- Upload, update or share a file in the drive you name.
- Reach an
@outlook.comdrive that the native connector never covers. - Work from mobile as well as a desktop browser.
- Act when a contract lands instead of at the next hourly sweep.
Nothing is merged. Each Microsoft identity keeps its own authorization, and every drive stays individually addressable.
Two recent changes matter before the account question
OneDrive is no longer a Perplexity connector in its own right. As of August 2026 it is one workload inside a merged Microsoft 365 connector, alongside SharePoint and Excel reads. And that connector is not read-only: it uploads files, updates them, and creates share links. If you have read anywhere that Perplexity can only search your files, that was true and is now out of date.
Settings → Connectors → find Microsoft 365 → click + → Microsoft sign-in → Accept. You invoke it by typing @Microsoft 365 in Ask.
| Verb | Available on a OneDrive |
|---|---|
| Natural-language search | Yes |
| Read files | Yes |
| Update files | Yes |
| Upload files | Yes, 64 MB from a Computer workspace, 4 MB inline |
| Browse folder contents and file versions | Yes |
| Excel workbooks | Reads only, no write verb named |
| Create share links, invite users, review or revoke access | Yes |
| Delete | Not individually documented |
Perplexity’s connector description contains the phrase “your OneDrive personal drive.” It is tempting to read that as a consumer Microsoft account, the @outlook.com or @hotmail.com kind. It does not mean that. The phrase sits inside a contrast list, distinguishing your own drive from a shared SharePoint document library. Microsoft Graph does use “personal” as the drive type for consumer OneDrive, which is where the confusion comes from, but the sentence resolves against that reading.
Nothing in Perplexity’s help centre states a per-connector account limit, describes a second-account flow, or refuses one. There is no add-account control on the tile, one status, and the documented fix for a broken connection is to disconnect and reconnect Microsoft 365. The nearest adjacent fact is a limit on a different connector: the Outlook.com connector documents that it can only query one primary calendar. Assume one identity per grant.
| What you have | Native path in Perplexity |
|---|---|
| One work tenant, desktop browser | Yes, from Pro |
A consumer @outlook.com drive | No documented path for files |
| Two work tenants | Undocumented, one grant on the tile |
| Naming which drive an instruction means | Not documented |
| Any of this on mobile or the desktop apps | No, web browser only |
| Acting when a file lands | No, hourly polling is the floor |
Nothing fires when a file lands
Connecting an MCP server gives an assistant reach, not initiative. The protocol has no callback mechanism, its Triggers and Events group is still drafting the first proposal for one, and both reference implementations remain unbuilt. Carly covers the gap: it watches thousands of apps and runs the workflow the moment something happens, then reports back through the same chat.
Perplexity’s unattended surface is Scheduled Tasks in Computer, and it is a clock. Tasks “support any recurring cadence as long as it runs no more often than once per hour,” and sub-hourly cadences are explicitly unsupported. Every run consumes Computer credits, and runs are skipped when credits run out.
Perplexity contradicts itself here. One overview page states that Computer “can monitor your email, calendar, flight status, and files with condition-based triggers.” It names files directly. But no mechanism appears anywhere in the Scheduled Tasks documentation, no folder or file trigger is described, and the hourly floor is stated as a hard limit. The document that tells you how to configure something is the one describing polling.
The practical effect is a floor. A contract that lands in the drive at 9:05 waits until the ten o’clock sweep, and you pay credits for every sweep that finds nothing.
Perplexity versus Carly on OneDrive
| Need | Perplexity | Carly |
|---|---|---|
| Search a work OneDrive | Yes | Yes |
| Upload and update files | Yes | Yes |
| Reach a consumer Microsoft account’s drive | No documented path | Yes |
| Hold two Microsoft identities as separate connections | Undocumented | Yes |
| Name which drive an instruction means | Not documented | Yes |
| Per-tool allow, ask, or disable controls | Yes, 55 tools | Approval on writes |
| Work on mobile or the desktop apps | No, web browser only | Yes |
| Act when a file lands | No, hourly polling at best | Yes, on the event |
| Cost of checking every hour | Computer credits per run | No polling needed |
Carly authorizes per identity, so a work drive and a personal drive sit side by side as separate connections you can name in an instruction. It works on mobile and desktop rather than one surface, and it acts when the file arrives instead of asking every hour whether anything has.

Quick fixes
| Problem | Fix |
|---|---|
| No OneDrive tile in Connectors | There isn’t one any more; look for Microsoft 365 |
| It worked before and now returns nothing | The merge needs a fresh grant; disconnect and reconnect Microsoft 365 |
| A search result says the connector is read-only | That is the pre-merge article; the current one documents upload, update and share |
| Sign-in says it needs admin approval | Tenant-wide consent in Entra, granted by an administrator |
| A consumer Microsoft account will not connect | No documented consumer path exists for files; connect it to Carly instead |
| A second tenant has nowhere to go | Connect both to Carly and reach them through the custom connector |
| Nothing happens when a file arrives | There is no file trigger. Hourly polling is the floor, and each run costs credits |
Frequently asked questions
Can Perplexity connect to a personal Microsoft account’s OneDrive?
Not by any documented route. Its permission bundle includes one scope Microsoft does not list as consentable by a personal Microsoft account, and consent applies to the whole bundle. Connect that account to Carly and reach it through the custom connector.
Can I connect two OneDrive accounts or two tenants?
Not natively. There is no add-account control, one connection status, and the documented remedy for problems is disconnect and reconnect. Authorize each identity in Carly instead, and name the drive in the instruction.
Does Perplexity notice when a file is added?
No. Its scheduled tasks run no more often than once per hour, sub-hourly cadences are explicitly unsupported, and each run consumes credits. One overview page does claim condition-based triggers on files, but no mechanism appears in the documentation you would use to set one up. Carly runs on the event.

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."
