When Outlook will not let you save a draft in a shared or delegated mailbox, or when the request to open a sign-in window is dismissed, the add-in now says what happened and what to do about it instead of showing a general error.

When Outlook returns an expired sign-in, the add-in now signs you in again using your existing Microsoft session instead of asking for your password every time.

Fixed a sign-in loop where Outlook kept returning an expired sign-in and the add-in gave up with error MM-10. It now signs you in again instead of stopping.
