This is Exchange Server 2007 running on Windows Server 2003 R2 Standard SP2 x64.
The system has been running since late 2007
In October 2009 I installed a GlobalSign ssl certificate so that mobile workers could use Outlook, some using the https connection to Exchange, some preferring to use Outlook Web Access.
This is still working fine
However, recently I am getting errors in the Application Event log telling me that the current certificate for this server has expired, and yet the expiry date is clearly marked as October 2011
I should also add here that the status of the certificate has always appeared as 'Invalid' in the managment shell listing from the day it was installed (as shown in one of the attached screen shots)
Because of the recent errors appearing I am now concerned that the system may stop working, so I would like to find and correct this anomaly .
I did of course try to sort this out with Global Sign when the certificate was originally installed, but we failed. I eventually left it because the system was actually working fine.
As always any suggestions are welcomed.
