Did you install OOS in the exchange server?

Please note:

"Don't install any other server applications on the server that's running Office Online Server. This includes Exchange Server, SharePoint Server, Skype for Business Server, and SQL Server. If you have a shortage of servers, consider running Office Online Server in a virtual machine on one of the servers you have"

Our Office Online Server is running on a different server already. There are no other server applications installed(e.g. SFB, Sharepoint, SQL Server) on that server.

Please use the following code:

Restart-WebAppPool MsExchangeOwaAppPool

It will restart the Ms Exchange OwaAppPool.

Which server shell we execute this command?

Exchange Server Management shell or Office Online Server?

Is there any impact to run this command?

I've updated my last reply, please run this command in the Exchange Server Management shell.

It will restart the Ms Exchange OwaAppPool.

We have executed the following command from Exchange Management Shell,

Restart-WebAppPool MsExchangeOwaAppPool

Still this issue persists.

Please run the PowerShell script Get-OfficeWebAppsMachine and see the output healthy/unhealthy.

In addition, it is possible that this is being caused by a firewall blocking the port, please turn off the firewall and try again.

@MdALAmran-4721,
Our Team uses SharePoint Online and we are receiving the same error.

Is there a place to run the provided code: Restart-WebAppPool MsExchangeOwaAppPool for SharePoint Online?

@Jules Caruso

Sorry for the late response.

This command is related to Exchange Server, it will not execute in SharePoint Online.

@Itch Sun-MSFT

We are using DDOS protection by using Cloudflare which was the issue and we are getting the error to preview Word, Excel from External Network.

We have resolved this issue by installing an appropriate Public SSL wildcard certificate which root CA is the same in Cloudflare & Office Online Server.
