Hello
I have a problem with Lync promting user to login to the EWS service.
There is a lot of articles regarding this issue on the forums out there. But all the articles address issues with the autodiscover endless passwords promt and EWS not beeing deployed at all. That is not my case.
If the user types credentials one time for every login to Lync, everything is okay. But this promt should not be shown at all....
The EWS service is deployed, and if i right click on my lync client while holding the CTRL down I can in the configuration information that it is the correct EWS URL.
If i manually browse the EWS URL in Internet Explorer I see the webservice WITHOUT having to enter any credentails (it uses my AD credentials that I'm logged in with)
If Internet Explorer understand to use my AD-Credentials for authentication to the EWS webservice - I can't understand why the Lync client fails to do so???
This error has started after we have added another SIP domain so we now have to SIP-domains. Certificate (wildcart) and aotudiscover is ok.
Best Regards, Steffen.
