You might see the following 2 Event ID’s on your server if your have certificates in the wrong store:
- Event ID 32042 LS User Services
Invalid incoming HTTPS certificate
cause: This can happen if the HTTPS certificate has expired or is untrusted
and
- Event ID 32042 LS User Services
Sending HTTPS request failed. Server functionality will be affected if messages are failing consistently. Sending the message to https://wwwserver.company.com:444/LiveServer/Replication failed
Solution:
Open up Lync Management Shell and run the following command:
- Get-Childitem cert:LocalMachineroot -Recurse | Where-Object {$_.Issuer -ne $_.Subject} | Format-List * | Out-File “c:computer_filtered.txt”
If the text file lists certificates then you know which ones to remove/move. After you have cleaned up, reboot your server and all should be fine.
One thing to also take note of, your Lync client will show other users status as “Updating”. Once the server is rebooted it changes to there current status.
Hope it helps.
