In the Notes 8 standard client emails
are rendered by the currently installed Internet Explorer instead of using
the Notes internal rendering engine (independently of the "default
browser" setting). The advantage of using Internet Explorer is the
improved quality of the rendering of MIME emails. See IBM's
Technote on this subject.
However, this may cause some trouble
when using Notes 8 and Internet Explorer 8. It happens occasionally that
users complain about a massive performance loss when opening emails in
Notes - 30 to 60 seconds, until the email is rendered.
Alex Carmack wrote a very interesting
posting about what can cause this issue: My
solution to slow opening emails
The slow MIME email rendering is caused
by security programs (like the popular Spybot
S&D). They add thousands of
sites to the Internet Explorer's restricted zone. But it seems that not
only Notes suffers from this but als other programs: Internet
Explorer 8 issues
They also suggest installation of a
patch for Internet Explorer: KB969897
The problem is caused by the "Immunize"
function of Spybot, but it can be solved with some tuning in the settings:
A prior run of "Immunize"
can't be undone by changing the settings only - by selecting only the marked
lines and press Undo -, it is also needed to clear some sites in the Internet
Explorer zones list (internet options/security tab) or some cleanup using
RegEdit to delete entrys in following Registry keys:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\ZoneMap\Domains
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\ZoneMap\EscDomains
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet
Settings\ZoneMap\Domains
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet
Settings\ZoneMap\EscDomains
HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\ZoneMap\Domains
HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\ZoneMap\EscDomains
Another workaround is to set the "Disable
embedded browser for MIME mail" in Notes client's perferences, this
disables the use of Internet Explorer and Notes will use the old internal
rendering mechanism again:
After that has been applied the mails
may look a little different, but at least it is much faster.
It is also possible to downgrade the
Internet Explorer to version 7 as the above issue applies only to Internet
Explorer 8.
