You create a Space in Perplexity and share the invite link with a colleague. By the time they click it, the link shows as expired or invalid. This happens consistently with every new invite you generate. The problem is caused by a specific permission setting that automatically invalidates the link after a single use or a short time window. This article explains why the link expires immediately and provides the exact steps to fix the issue.
Key Takeaways: Fix Perplexity Space Invite Link Expiration
- Space Settings > Invite Link Expiration: Change from “After First Use” or “1 Hour” to “Never” to stop immediate expiration.
- Generate a New Link After Changing Settings: Old links retain their original expiration setting even after you update the Space.
- Check the Recipient’s Perplexity Account: The invitee must log in with the same email address the invite was sent to.
Why Perplexity Space Invite Links Expire Immediately
The immediate expiration is not a bug. It is the result of the default invite link expiration setting in Perplexity Spaces. When you create a new Space, Perplexity sets the invite link to expire “After First Use” by default. This means the first person who clicks the link uses it, and the link becomes invalid for everyone else. If the recipient does not click the link within a few minutes, the link may also expire based on a short time limit.
There are two expiration mechanisms at play:
Expiration After First Use
This is the default setting. As soon as one person opens the link and joins the Space, the link is deactivated. If you test the link yourself before sending it to a colleague, you become that first user. The link then shows as expired to everyone else.
Expiration Based on a Time Limit
Perplexity also applies a time limit to invite links. The default time limit is one hour. If the link is not clicked within that hour, it expires automatically. Some users report that the link expires in as little as 15 minutes. This is not documented in Perplexity’s official help pages, but it is a consistent behavior reported by many users.
The combination of these two settings causes the immediate expiration you see. Changing both settings to “Never” resolves the issue.
Steps to Change the Invite Link Expiration Setting
You must change the expiration setting inside the Space itself. You cannot change it from the invite link popup. Follow these steps exactly.
- Open the Space where the invite link expires
Log in to Perplexity in your web browser. Go to the left sidebar and click the Space name. The Space opens in the main panel. - Click the three-dot menu next to the Space name
Look at the top of the Space panel, next to the Space name. Click the three horizontal dots. A dropdown menu appears. - Select “Space Settings”
In the dropdown menu, click Space Settings. A new page or panel opens with configuration options for that Space. - Locate the “Invite Link Expiration” dropdown
Scroll down until you see the section labeled Invite Link Expiration. It is usually near the bottom of the settings page. The default value is “After First Use” or “1 Hour”. - Change the setting to “Never”
Click the dropdown and select Never. This removes both the first-use limit and the time limit. The link will remain active until you manually revoke it. - Click “Save” and generate a new link
Click the Save button at the bottom of the settings page. Then close the settings panel. Click the Invite button in the Space to generate a brand new invite link. Copy this new link and send it to your recipients. The old link is still expired. Only the new link has the updated expiration setting.
If the Invite Link Still Expires After Changing the Setting
If you changed the setting to “Never” and the link still expires, check the following issues.
I changed the setting but the old link still shows as expired
The expiration setting applies only to newly generated links. The old link retains its original expiration. You must generate a fresh invite link after saving the setting. Click the Invite button again and copy the new URL.
The recipient sees “You do not have access to this Space”
This is not an expiration issue. The recipient is either not logged in to Perplexity or is logged in with a different email address. The invite link is tied to the email address you entered when you sent the invite. Ask the recipient to log out and log in again using the exact email address that received the invite.
I cannot find the Invite Link Expiration setting
This setting is only available in Spaces created after Perplexity released the expiration feature. If your Space was created before that update, the setting may not appear. Create a new Space and test the invite link. The setting should be present in new Spaces.
The link expires after a few minutes even with “Never” set
This can happen if you are using a shared or public Wi-Fi network that caches or modifies URLs. Try generating the link from a different network or a private browser window. If the problem persists, contact Perplexity support through the help menu in the app.
Perplexity Space Invite Link Settings: Before and After Fix
| Item | Before Fix (Default) | After Fix (Changed to Never) |
|---|---|---|
| Expiration after first use | Enabled — link dies after one click | Disabled — link works for unlimited clicks |
| Time limit | 1 hour (or less in some cases) | No time limit |
| Link reusability | Single-use only | Multiple uses by different people |
| Old links remain valid after setting change | No — old links keep original expiration | No — you must generate a new link |
| Recipient must log in with the same email | Yes | Yes |
You can now control exactly how long your Perplexity Space invite links remain active. Change the Invite Link Expiration setting to Never for permanent access. Generate a new link after saving the setting. For Spaces that need temporary access, consider setting a specific time limit instead of After First Use. This gives you more control over who joins and when.
