i configured since a while active sync and published it using adfs and wap. it was working great.
relying party trust created type : non claims aware
publishing on wap using adfs: rich clients

starting the last night, it stopped working with an error: the username or password are wrong.
however, nothing has changed.
these event ids are in the event viewer of adfs

    Error 521 indicates the any one of the following user actions needed

    User action:
    Examine the request and verify that at least one of the following parameter sets are present.
    Username and password
    Username, password, and device registration certificate
    User certificate

    Probably, check the certificate at first and see the certificate is still valid

    adfs proxy trust on adfs personal store shows 2 certifcates: both of the are expired.
    but owa is still working.
    just activesyn is not.

    however, how can i renew the certificate? the adfs proxy certificate is different that the one used for adfs wap and exchange which is a wildcard one.

    "the proxy trust certificate is a rolling certificate valid for 2 weeks and periodically updated. This is stored in an internal, protected store so you won’t see it in any of the usual certificate stores. "

    if the above is real, then why i am seeing proxy certificates are expired in the personal store.
    in addition, owa is working fine usinf adfs and wap. the issue is just with activesync. and wap config is green

    the client informed me, that the activesync stopped working while the pdc was rebooting. however, the pdc is running now but the issue is still persisting

    any ideas
    tahnk you
