After installing exchange 2013 culmative update 1 on the exchange server. Outlook 2010 will not connect, and keeps throwing up error: the name of the secure certificate is invalid.

I can connect through Outlook Web Access, just not through Outlook 2010.

Hi Ajax68,

Thank you for your question.

This error is related to certificate. We should troubleshoot Exchange certificate.We could rebuild profile to check if the issue persist.

If the issue persist, we could check if the NetBIOS name of mailbox which outlook are connecting to match certificate name.

We could refer to the following links:
