Continuum to my previous messages:

Problem description: Account Setup -> Add Account -> Mail for Exchange fails;
a) Sign in offers an "incorrect certificate", after accepting setup fails with "Check account settings.",
b) Manual Setup throws screen with login credentials continuously w/o error, unless route a) has been taken 1st.

Workaround: No workaround known/found.


Tried adding the (very valid and CA signed) SSL-certificate manually over Blutooth from OWA/Webmail to the N9. It was installed properly under Settings -> Security -> Certificates and visible under e.g. User certificates (the whole chain).

Did not help with the problem. Another certificate is still being offered when choosing the "Sign in" -option (as previously explained). Note that this particular certificate does not seem to get 'Saved' anywhere, at least I cannot find it in the same store. This would lead to think that the N9 has also a secondary certificate store, like supposedly the N900 has/had in the past?

Nothing gets into activesync.log from multiple tries of setting up an MfE account.

(Please note that I'm not trying to access over Corporate network, but public Wifi and 3G. Logging into the webmail does not and has not prompted any certificate notifications.)

Ideas?

Update: Case a) reason seems to be that the automatic settings with firstname.lastname@domain.com connects to another server, which is not the same as webmail.domain.com and the Exchange auto-discovery does not work (noticed that the certificate has another hostname than our webmail-server).

Still, manual settings do not fly either.
