Microsoft Research: E-mail Loss Detection Add-in (ELDA) Known Issues

E-mail Loss Detection Add-in (ELDA) Known Issues

  • ELDA has to "see" all the mail that is delivered to you in order to function correctly. This means that if you use other e-mail client software, including Outlook Web Access (OWA) and Outlook Mobile Access (OMA), to access your mailbox while Outlook is not running, you should not permanently delete mail using these clients. Only deletes that move the deleted mail to the "Deleted Items" folder (for example, Exchange) or which simply mark the mail for subsequent permanent deletion (for example, IMAP) should be performed via these clients.
  • Further, if you delete a mail from your Outbox folder before it is picked up for delivery this will result in a spurious delayed/lost notification being generated at the recipient's end.
  • ELDA only works with Outlook profiles that contain a single mailbox. The profile may contain one or more PST stores, but only one mailbox. If you have multiple mailboxes you must create a profile for each.
  • A restriction for using Hotmail, IMAP, or POP3 mailboxes is that you must only run Outlook on one computer. This restriction exists because for these mailbox types ELDA stores state data locally in the PST file. A popup is shown every time you start Outlook reminding you of this restriction.
  • ELDA can only detect up to three consecutively delayed/lost mails. If the batch of mails lost is greater than three then ELDA will only notify you about the 3 most recently delayed/lost mails.
  • Mail you receive as a consequence of membership in a distribution list does not have ELDA protection.
  • When sending to multiple recipients, ELDA will only provide protection for the first three (non-distribution-list) recipients.
  • For implicit user addition, mail exchanges must have a single recipient and must include at least one reply.
  • ELDA only offers protection for normal mails and meeting requests. For example, it offers no protection for RSS Feed Sharing mails.
  • All expected mail state will be cleared if you rename, delete, or add any folder to your mailbox. While undesirable, this is not a bug, it is expected behavior. Similarly, all expected mail state will be cleared if more than 200 new mails have arrived since you last ran Outlook.
  • ELDA "polls" for new mail when used with a Hotmail or POP3 mailbox. You can control this frequency via the "Settings" dialog. Be aware that the range for this setting is capped by your setting for when to declare a mail as delayed.
  • Under certain rare conditions ELDA may generate spurious delayed/lost notifications if mails are received in an order different from the order in which they were sent.
  • If you are running Outlook Connector and have .Net assembly binding logging enabled (via Fuslogvw.exe) then Outlook may hang at startup. To resolve the issue, disable assembly binding logging (using Fuslogvw.exe).
  • If you are running Outlook Connector you may occasionally see a "Human Interaction Proof" challenge appear even when you are not trying to compose/send a mail yourself. This occurs because ELDA itself can generate mails, for example when the Allow Automatic Response to Resend Requests option is enabled, or when deleting an ELDA user.
  • You can deactivate the ELDA add-in at any time from Tools » Trust Center » Add-ins » Click Go » Uncheck Microsoft Research Email Loss Detection Add-in (ELDA) » Click OK. Or you can completely uninstall ELDA from Control Panel » Add/Remove Programs (Windows XP) or Programs and Features (Vista). Locate Email Loss Detection Add-in in the list, and then click Remove.
  • The ELDA add-in may become inactive after installing Visual Studio 2008. To resolve this issue you should stop Outlook and repair ELDA from Control Panel Add/Remove Programs (Windows XP) or Programs and Features (Vista). Locate Email Loss Detection Add-in in the list, click Change, click Repair, and then click Finish.
  • In Microsoft Windows Vista, when reading e-mails with embedded hyperlinks, a tooltip usually appears over a hyperlink that the mouse is resting on. With the ELDA add-in installed, this tooltip may flicker out too quickly for you to read.
