Can't view any document in OWA with Exchange Server 2016

89770-office-online-error.png


I have an exchange server 2016 environment where i have 2 mailbox servers, 1 edge, 1 reverse proxy and 1 office online server. I am facing this problem for few months. When i open an attachment in my owa i am getting "server error in '/' application" error. I applied huge solutions from google, microsoft docs but still can't fix it. I rebuild my office online server and rebuild server farm also but i can't fix it. Can anyone give me the appropriate solutions to fix this issue? Thank you.

Hi @MdRubiatHaque-0645 ,

Please check the below,
1.Office Online Server health status - (Get-OfficeWebAppsFarm).machines
2.Are you able to browse the URL - http://servername/hosting/discovery
Replace servername with OOS server name/URL
3.Check if WacDiscoveryEndpoint is configured on the Exchange mailbox server level
Get-MailboxServer | Fl Name, WacDiscoveryEndpoint

Hi @AshokM-8240 ,

Thanks for your helpful reply.
1. Office Online Server health status is unhealthy. If you have any document how to mitigate it then please provide me.
2. I am able to browse the URL - http://servername/hosting/discovery
3. My WacDiscoveryEndpoint is configured on organization level. So, in that case what should I do now?

For office online health status, check the first blog which I shared in earlier post.
Try setting the WacDiscoveryEndpoint at the mailbox server level.
