5. no event log errors, only about exchange performance counters.
all what i did:
*recreate owa. recreate ecp directories in default website and backend website also ecp pool, and add it back.
*check website biddings;
*remove and readd certificate.
*disable OWA cache option.
*check user language options.
*check running services.
*check owa proxy health
* check owa and ecp authentification settings
* check for correct internal external url settings for owa and ecp.
* try with ssl req checked in or checked out -not help.
* try with redirect options disabled or enabled- not help
