Let's Encrypt certificate for email server expired

A user sent me a screen shot she took with her phone of a message she saw while checking her email with Microsoft Outlook 2016 which stated:

Internet Security Warning

The server you are connected to is using asecurity certificate
that cannot be verified.

A required certificate is not within its validity period when
verifying against the current system clock or the timestamp in
the signed file.

Do you want to continue using this server?
