Base: 257824 OL2000: Differences Between Outlook and Outlook Express SUMMARY Microsoft Outlook 2000 supports the Internet Mail Access
Protocol 4 (IMAP). This open Internet e-mail standard uses server-based mail
storage. Because its storage is server-based, there are differences between it
and other e-mail protocols. The following are the major differences.
MORE INFORMATIONNo Non-Mail Folders Can Be Stored on an IMAP Server Due to limitations of the IMAP protocol, as well as for
efficiency and interoperability concerns, Outlook does not allow non-mail
folder storage on an IMAP server. No Mail "Special Folder" Can Be Stored on the IMAP Server Your Sent Items, Drafts, and Deleted Items folders cannot reside
on an IMAP server. Outlook requires that all special folders exist in the
default store. IMAP cannot act as the default store because it cannot contain
the non-mail special folders.
You can simulate a server-side Sent
Items folder by creating a rule in Rules Wizard that copies all outgoing mail
to the IMAP folder of your choice. There is no workaround for Drafts and
Deleted Items. Different Deletion Model Deletion works through marking items for deletion and then
purging all items marked for deletion in a given folder. There is no Deleted
Items folder because moving an item in IMAP is inefficient; the source item is
not immediately deleted due to the two-phase deletion model. This requires that
you double the storage requirement for that message. Unable to Start Outlook in the IMAP Inbox Even if you use only IMAP accounts, or your IMAP account is set
as your default mail account, Outlook will still launch into a POP3 inbox, the
Inbox of your default store. This is because IMAP cannot act as the default
store.
As a possible workaround, you can create a shortcut to the
Inbox of the IMAP store on your desktop, and start Outlook from this shortcut. Outlook Today Does Not Display Information for Your IMAP Inbox Even if you use only IMAP accounts, or your IMAP account is set
as your default mail account, Outlook Today will only show the unread count
from your POP3 Inbox, the Inbox of your default store. This is because IMAP
cannot act as the default store. New Mail Notifications You will get a new mail notification only if you have a
persistent connection to the IMAP server. If you are using a dial-up connection
to retrieve e-mail from the IMAP store, you will not receive a sound, the
pointer will not change briefly, and the envelope icon will not appear in the
system tray. Net Folders Do Not Function with IMAP The Net Folders component depends upon the Rules Wizard and
therefore will not function when used with an IMAP mail server. Contact Linking Does not Function with IMAP In Outlook, Contacts can contain activity information such as
mail received from a particular contact. This type of activity tracking cannot
be linked to an IMAP store. To work around this, use the Rules Wizard to create
a rule that moves all incoming mail from the IMAP inbox to the inbox of the
Personal Folder. Activity tracking can then be based on this Inbox.
