Ok then please help me.
I now have an IMAP account only.
MY isp uses Google to store its mail so I have a set of personal folders
which include an inbox/outbox/sent items etc.
Q1 do I just collapse them and pretend they are not there or do they serve
a purpose?
Since IMAP cannot support a calendar, contacts, tasks, or a journal (i.e., any
non-mail type of folder), Outlook must have these folders. Moreover, an IMAP
account's folders cannot be specified as the default folders in Outlook's mail
profile settings. Outlook always created the full complement of default
folders in its default folder file, so along with the non-mail folders, you
also get the mail folders, like Inbox, Outbox, Deleted Items, and so on. If
you do not use the non-mail features of Outlook, then, yes, those folders
won't help you. You should consider using a program other than Outlook in
that case. I hear Thunderbird is a good, free mail client that handles IMAP
accounts well.
In my IMAP folders I have a Google Mail folder which has
All-mail/Bin/Drafts/Sent Mail/Spam/Starred
Q2 do I collapse this until I need it?
I usually specify "[Gmail]" as my folder root in the IMAP account settings. I
then right-click the IMAP folder root in the Navigation Pane, choose IMAP
Folders, and subscribe only to the folders I wish to see, selecting the option
to hide all non-subscribed folders. "All Mail", "Spam", and "Starred" are not
among the folders I want to appear. Doing this makes the gmail folders all
appear just under the root like Outlook normally presents folders.
In my IMAP folders, but outside Google Mail I have another Inbox (and all
the folders I dragged from my pop account before I deleted it.
Q3 Are these really the only folders I need?
That's fine. If you have moved all your messags to the server. Since they're
not under the "Gmail" structure, my method of configuring the account won't
work well for you unless you put those folders at the same level as the normal
Inbox (which means you'd probably have to rename the extra Inbox you created
that's "outside".
