Sometimes, you might encounter a temporary email server error. These might happen for any of the following reasons:
- The connection is blocked due to excessive use.
- Login failed due to an unknown email server error.
- The account is turned off.
- Network connection issues.
- Too many simultaneous connections.
- Temporary authentication failure.
When this happens, Nylas recommends you retry your request. If the request continues to fail, contact your email administrator or provider for further troubleshooting.
