Login fails (Exchange 2007)

There is a known issue where a login fails to an Exchange Server 2007. It seems users that have been migrated from Exchange 2003 to Exchange 2007 cannot get accessed via WebDAV protocol under certain circumstances. This is not a general failure, but it happened in two cases now. It seems to be an Exchange bug.

If your login fails try to create a new user and connect with this newly added user.

We work on this issue.
