How to fix error “Cannot invite existing user”

Seeing this error when trying to invite a team member?

It pops up because the email address you’re trying to invite is already registered in Multilogin. Here's how to fix the issue ⬇️

Option 1: use a different email address

Ask the team member to provide an alternate email address they can access. This email can be a personal one, a work email, or any unused email that’s not currently linked to Multilogin.

Proceed with the invitation using this alternate email.

Option 2: use an email alias

If the original email is [email protected], you can modify it by adding a “+” and extra text before the “@” symbol, like [email protected] or [email protected]. Most email providers (like Gmail) treat aliases as the same email, so the invitation will still arrive in [email protected].

The team member can then accept the invite without needing to create or manage a new account.

This trick works with Gmail and some other email providers. If unsure, test the alias first by sending a quick test email.
