Note There can be several reasons why a digital signature is not valid.
For example, the sender’s certificate may have expired, it may have

certificate is unavailable. Contact the sender to report the problem.
Manage folders
Each Messaging account has its own folder hierarchy with five default
Messaging folders: Inbox, Outbox, Deleted Items, Drafts, and Sent
Items. The messages you receive and send through the account are
stored in these folders. You can also create additional folders within
each hierarchy. The Deleted Items folder contains messages that
have been deleted on the device. The behavior of the Deleted Items
and Sent Items folders depends on the Messaging options you have
chosen.
If you use an Outlook e-mail account, e-mail messages in the Inbox
folder in Outlook will be synchronized automatically with your device.
You can select to synchronize additional folders by designating them
for synchronization. The folders you create and the messages you
move will then be mirrored on the e-mail server. For example, if you
move two messages from the Inbox folder to a folder named Family,
and you have designated Family for synchronization, the server
creates a copy of the Family folder and copies the messages to that
