yes specifically droid1 and exchange 2010.
2007 works for some.
2003 works for all droid1's.
stock droid1 on frg083 will also fail against exchange 2010.
touchdown for exchange works on them all on all models and is a hell of a lot better anyway.
gflam exchange is different animal. k9 will fail on exchange 2010 also.
really, do yourself favor and grab touchdown, so many more features.
The strange thing is that this is working for me in UD 2.5 an I believe it worked fine in Sourcery 1.0, I might install Sourcery again and give it another try. I think we are running exchange 2003
2003 tends to work for most, as in no inherent code issue, as it handles http/https in a whole different manner and was allowed self signed ssl certificates.
in your case a reinstall may solve it, but I still stress touchdown as its just SO much better.
I am doing an update rollup on exchange 2010sp1 server here which may address some issues. if not I have test account setup and a dev is going to help try to see what we can do on this end.
there haave ben reports editing a file works with ex2007, but for non rooted stock droids its not much help.
would like to mention its NOT rom specific, just talking about it here since it was mentioned here.
