Think about a group account: sales at our.domain
You want people to operate in there, so somebody can make an appointment
with the sales section and you have a real calendar and stuff.
To be able to comfortable work with three outlook clients
on the group account, they all need to see the emails immedeately (within minutes).

Yes, the bad part is that it also needs pop to send out ical messages.
From my understanding only the pop part can parse and create iCalendar.
This is why a plug-in does not have a huge choice.
So we are looking for a solution for this.
Solutions that I have disregarded so far:
a) Implementing an iCalendar parser in the plug-in would
only solve this partially as OL still does only on the current folder
for registrations. Beside that it bears high risks and quite some work.
b) A pop3 proxy, but this would have a hard time fighting against
a lot of anti virus software that hooks into the pop3 transport by various
For Proko2 it is acceptable that only for registration of invitation messages
somebody has to change the outlook profile and get the message via pop.
So we only need to transport the other emails to the default.inbox.

In a setting with a permanently running Kontact in the group, this would work,
but this is quite dirty as you can imagine.
But we think of a sales@ group with only OL clients,
even one permanently running OL getting all the pop3 stuff would solve the issue.
So I aim to not have a permanently running client.

The server should be able the see imap annotation.
(If we do not have that imap annotation yet, we should start using it.)
I had hoped that we already mark the standard folder with an imap annotation.
A faster solution could be to make this folder configurable, too. (hmm?)

That is fine, I want you to understand the problem of course.
Please let me know immedeately or call me, when this still is unclear.
We need this in the next two days.
