Re: page cannot be found
see: http://support.microsoft.com/kb/823175/
section Known Issues, subsection: OWA
that is to say:
DenyUrlSequences. In the [DenyUrlSequences] section, sequences that are
explicitly blocked can potentially affect access to OWA. Any mail item
subject or mail folder name that contains any one of the following character
sequences is denied access:
⢠..
⢠./
⢠\
⢠%
⢠&
For example, the following folder does not work because the Projects mailbox
folder contains a trailing period. The trailing period causes the folder to
be excluded because of the explicit deny for the ./ sequence:
/Server/Exchange/My Folders/Projects./Costings.eml
The following folder also does not work, because the explicit deny of the ..
sequence prevents directory traversals:
/Server/Exchange/Inbox/My .. message.eml
If you experience any additional issues when you try to make OWA requests
with Urlscan enabled, check the Urlscan log files for the list of requests
that are rejected. The following is the default location of the Urlscan log
files:
WinDir\System32\Inetsrv\Urlscan\logs
By default, in the [DenyUrlSequences] section, escaping ("% ; Do not permit
escaping after normalization.") is disabled. However, this setting does not
work for OWA when the mail subject contains Cyrillic characters (or any
other character that appears as %character).

Re: page cannot be found
Cosimo,
Thanks for all the info. I will have to do some more research on all this.
