About junk email settings in Exchange at IU

Email sent to IU Exchange accounts is analyzed by both Microsoft and UITS spam engines, with messages that are likely to be spam routed to the Junk Email folder. Mail in the Junk Email folder is automatically deleted after 30 days.

You can recover deleted items in some circumstances; for more, see Recover deleted items from Exchange at IU.

Note:
Microsoft does not release its spam algorithms, even to Exchange administrators at IU and other organizations, in order to prevent spammers from improving their spam techniques. Therefore, UITS staff will be unable to say why a given message was flagged as likely spam. To make sure you're seeing all the email you want to see, UITS recommends checking your Junk Email folder regularly, and following the instructions below to mark any false positives as safe.

In Outlook or Outlook on the web, you can fine-tune the spam analysis for your account by marking particular addresses and domains as blocked or safe. Your Safe Senders, Safe Recipients, and Blocked Senders lists are stored on the Exchange server. When Exchange's anti-malware protection evaluates a message, it looks at your personal lists before determining a delivery location.

To view an online summary of your Exchange account's Junk E-mail settings:

  1. Log into Outlook on the web.
  2. At the top right, click the Settings (gear) icon, and then at the bottom of the "Settings" window, click View all Outlook settings.
  3. If it isn't already selected, click Mail and then Junk email. From here you can view, add, and remove addresses and domains as "Blocked" or "Safe".
Note:

In Cached Exchange Mode, Outlook can also perform client-side evaluations of messages that are delivered to your inbox (that is, the filtering will take place within the desktop program on your computer, not on the Exchange server). You can select this by right-clicking a message and choosing Junk and then Junk E-mail Options. However, this method has two disadvantages: it will not apply when you access your mail on other computers, and if you set Outlook's level of filtering to High, you may have more legitimate email routed to your Junk Email folder.
