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.
