How to renew Office Online and OWA Certificate
It happens that certificates get expired so what do you need to do to handle this situation in case your office online /OWA certificate got expired this will make documents opening in SharePoint is broken.
To do that you have 2 ways:
After getting certificate either from certificate authority or self signed like here
1: Go to PowerShell in the office online/OWA server and run this command
Set-OfficeWebAppsFarm -CertificateName “New certificate Friendly name”
This will work if the office online is in good shape, so how I know that?
Run this command first: Get-Service wacsm
If it is running then it will work
2- The other way is just delete the old one and put the new one with the same name
- Open MMC console and add certificates snap-in, on the certificates Local computer | Personal | Certificates, delete expired certificate and import new one.
- Take a note of certificate name
- Open following directory (\ProgramData\Microsoft\OfficeWebApps\Data\FarmState\settings.xml)
- Open Setting.xm file with notepad
- Locate following line and make sure Certificate name matches the imported certificate name.
- Then you can restart the service using this command Restart-Service WACSM
In case you got issues this may be because you have not configured the correct TLS as mentioned here
