Question: How do I generate a CSR on Edge Server with Microsoft Lync 2010 Server ?


If you require an SSL certificate to secure a domain hosted in an Edge Server, you must first generate a Certificate Signing Request (CSR).

Do not use commas in any of the fields when creating your Certificate Signing Request (CSR). Commas are interpreted as the end of the field and will cause an invalid CSR to be generated.

Do not use any of the following characters in the Web server Distinguished Name: ! @ # $ % ^ * ( ) ~ ? > < & / \

1. Start > All Programs > Microsoft Lync Server 2010 > Lync Server Deployment Wizard
