Fixing Lync: Resources I Used to Solve Lync Issues, Errors and Problems

Like many of you, I am often searching on Google for a solution to a problem related to Lync (maybe just because I do not remember the solution I used last time I had the same kind of issue)
Here I will try to keep an updated list of problems encountered and sites or resources that I used to solve them, just in case they may come in handy.

Of course, a big thank you to the people who spent their time to write down the solution.


  • Lync Server 2013 Front-End installed on Windows Server 2012 R2. Events 30988 “Sending HTTPS request failed. Server functionality will be affected if messages are failing consistently” and 32178 “Failed to sync data for Routing group from backup store“. I had a couple of malformed C.A. certificates in my Trusted Root Certification Authorities store.  Verify with the following cmdlet and remove the certificates from the store   Get-Childitem cert:\LocalMachine\root -Recurse | Where-Object {$_.Issuer -ne $_.Subject} | Format-List *
