I have a TREO 750 and I can't browse two of our Exchange OWA web site. There an certificate error. The error said that the certificate have the good name and date but we don't trust certificate. I nstalled the root certificates on the treo. and they appear in the root store but still have the error.
I can browse this site (and also synchronise) with auther phone HTC 6800 with Windows mobile 6.0 on who I installed the same root certificates. We also can browse those ssl site from any XP pc.
I tried many thing (re-installl the certificate, Reboot the Treo take off batteries)
I would like to upgrade the os to Windows mobile 6.0 but ISP block that. Anyway the user of the is french and version 6 is english only for now.
Any help will be appreciate.
