Google Message Continuity User Guide - Manual (Page 3)

Root-level folders called ‘Trash’ or ‘Deleted Items’ are treated as Gmail system Trash folders. In other
words, messages moved to either of these folders are considered deleted and are moved to the Trash label
in Gmail.
Root level folders called ‘Sent’, ‘Sent Items’, or ‘Sent Mail’ are treated as system Sent Mail folders. In other
words, messages added to any of these folders are tagged with the ‘Sent Mail’ label in Gmail.
Folder-Label Mapping
For each folder on Exchange, Google Message Continuity creates a separate label on Gmail. System
folders on Exchange are treated separately and are mapped to system labels on Gmail.
In addition, Message Continuity will synchronize the existing Gmail labels to the Exchange store. In
practice, this means that two new folders "Follow Up" and "Misc", will be created in your mailbox. You also
have the option to remove these two folders ("Follow Up" and "Misc"). If you do remove them, the
corresponding labels in Gmail are deleted as well.
Google Message Continuity uses the following mapping for Exchange folders:
• "Inbox" on Exchange is mapped to the "Inbox" label.
• "Sent Items" on Exchange is mapped to the "Sent" label.
• "Deleted Items" on Exchange is mapped to the "Trash" label.
• "Drafts" folder on Exchange is mapped to the "Drafts" label on Gmail -- although this folder is not
synchronized in the current release.
• A root level user folder with a name such as "foo" on Exchange is mapped to the user label "foo"
on Gmail.
• The folder "bar", a sub-folder of root-level folder "foo" on Exchange, is mapped to the label "foo/
bar". This also means that Google Message Continuity treats "/" as a special character and users
cannot have folder names that contain that character.
Deleting Messages
When messages are deleted in Exchange, or moved to the "Deleted Items" folder, the "Trash" label is
applied to the corresponding message in Gmail. At this time, when a message is permanently deleted in
Exchange, the same is not done in Gmail. We leave it to the Gmail garbage collector to delete the message
with the Trash label after a few days. If the message is moved out of the "Deleted Items" folder to the "foo"
folder, the "Trash" label is removed and "foo" label is applied to the equivalent message in Gmail, only if the
message still exists there. If the message has already been garbage collected from Gmail, it becomes an
"out-of-sync" message. (This issue will be fixed in a future release).
