start page will not come up how do i fix it

Hi,

Which start page do you mean?

If you mean OWA and ECP page, which error messages when you open OWA or ECP page? We need error messages for troubleshooting, please take your time to collect some information.

Please check if there are any events in application logs.

Please check this issue via different browsers.

Thanks for your patience.

Best Regards.
