## Known Issues | Back to Top

This section describes known issues for Native POP3 Connector. These issues may impede your ability to successfully deploy and use it. You should familiarize yourself with all of the known issues listed here prior to installing the software.

Known issues are listed based on setup errors and resolutions:

#### After upgrading to the latest version there are e-mail duplicates in mailboxes

#### Cannot enable Schema Updates

#### Cannot modify Schema

#### Resolution for Schema issues

### After upgrading to the latest version there are e-mail duplicates in mailboxes | Back to Issues

After Native POP3 Connector internal database format has changed it removes previous version during upgrade process.
Stop Native POP3 Connector service, delete *.db files in the NPC's installation folder and start Native POP3 Connector service in this case.

### Cannot enable Schema Updates | Back to Issues

If setup reports this error during installation progress, most likely Schema Master computer is not the same with the Native POP3 Connector and setup cannot enable Active Directory Schema remotely.
See resolution below.

### Cannot modify Schema | Back to Issues

If setup reports this error during installation progress, most likely logged in user has no Schema Admin rights because he(she) is logged on a sub-domain.
See resolution below.

### Resolution | Back to Issues

In both cases above you have to use the following installation scenario:

- Active Directory modification:
  On the Schema Master computer (usually Primary Domain Controller) using user account with Schema Admins rights run setup, select Custom installation type and disable Native POP3 Connector components feature. Install the product with Active Directory Schema modifications only.
- Product setup:
  On the computer needed using user account with Domain Admins rights (in the domain which this computer belongs to) run setup, select Custom installation type and disable Active Directory Schema modifications feature. Install the product with Native POP3 Connector components only.

## Uninstallation | Back to Top

You can always uninstall Native POP3 Connector using Add/Remove Programs Control Panel applet.

If you want to keep existing Native POP3 Connector configuration, do not remove Native POP3 Connector from Exchange System Manager. In this case, it will retain its Active Directory objects in your Forest.

If you want to remove Native POP3 Connector completely, make sure to remove all of its instances using Exchange System Manager before uninstalling it with Add/Remove Programs.
