Hi Seward,

I have few questions, can you please clarify it?

What you shared (July 2020) and I have shared (Jun 2020) both are release only right? not CUs correct?

if we install Jul 2020 does it take care of June one also?

if we install only June 2020 release does it any harm

if we install June 2020 Build number changes from 16.0.10338.20039 to which BUIlD number? and for July which Build number?

I am not clear on 3 rd step form the link you have shared for multi server farm steps, can you please guide me whether we have to implement 3rd step or not?

Please help. Thank you

All OOS updates are cumulative since the last major release (Nov 2018). Installing June isn't an issue, but you miss out on the security fixes offered by July. Yes, the build number changes with each release.

Step three refers to major releases, which you already have from Nov 2018.

Hi Seward,

Please confirm if we need to uninstall existing online server ? as we are on Nov 2018 build downloaded from Volume Licensing site.

All I need to know is Do I need to uninstall existing office online?

Correct, you do not need to uninstall OOS for month-to-month patches, as noted in that article.

sorry to trouble you, please clarify me on my last question.

can you please provide me the reason why we no need to uninstall office online product? (3rd step)
I understand that we already on Nov 2018 build, we want to know what is the exact reason? what is covered in Nov 2018?

You only need to uninstall OOS when a new ISO is released (major version). Month-to-month patches do not require that step as you're patching the major version.
