thank you all and sorry for my late response i was totally booked, i figured out i just need to add the version number on the url
could it be because we have different CU levels 2016 CU 16 and Cu 18 on other servers
https://Mailbox01/ecp/?ExchClientVer=15.
also it seams to be a service issue as even the above url does not work sometime but that seams to be another case
Hi,
Could you please provide more information,
Is this a new installation
Are you getting the ECP login page while browsing https://localhost/ecp?
Error message appears after providing credentials or while browsing https://localhost/ecp
Does it happen to one user or all users?
Is OWA working fine
Can you check the below,
Check if ECP App pool is running, try recycling it -> IIS -> ServerName -> Application Pools -> MSExchangeECPAppPool
Check the Authentication, Get-ECPVirtualDirectory -Server "ServerName" | fl Identity,auth. It should be same as OWA
Is it the case that you've recently installed an update? Let's say, CU18? In this case please check what you find in IIS Manager -> Sites -> Exchange Back End -> ecp -> Application Settings -> BinSearchFolders. It may be the case that there are incorrect information.
How to solve?
Run an elevated EMS and navigate to the scripts folder %ExchangeInstallPath%\Scripts
Run the .\UpdateCas.ps1
Run the .\UpdateConfigFiles.ps1
After this, you perform an IISRESET, but WITHOUT forcing to do so. When finished, ECP should work again. I wrote a german blog article discussing this topic in March this year.
re-run the CU update ensure you are running in admin mode. (cmd prompt admin mode)
