i was already connected with url to ECP , OWA correctly and without issue .

but today when attemp login to ECP , OWA Back to login page and not enter .

what is my problem and  solution ?

Hi MHM,

Thank you for your question.

If there is Exchange 2010 or Exchange 2007 in organization, we could access ECP by the following URL:https://CAS15-NA/ecp/?ExchClientVer=15

If there is just Exchange 2013 in organization, we could  access ECP by the following link:https://CAS15-NA/ecp

We could try to restart IIS to check if the issue persist.

We could refer to the following link:

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,

Thanks for attention

i dnt have every thing except exchange 2013 . 

i do this but not correct .

i cant enter to url yet .

Hi MHM,

Do you mean you didnt type all URL in browser?

You could give me more details for our troubleshooting, for example:

Which URL you cannot enter?

Did you login owa to send emails?

When we want to access ECP, we could type https://casname.domain.com/ecp.

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,

Jim
