Why are emails disappearing from OWA?
If emails are disappearing from OWA after you click on them or after they have been read, it is likely that you have a display filter applied to one or more of your email folders.
To remove the display folder, you need to carry out the following steps:
- Click on the folder you are having issues with
- From the options options in the top left of the OWA window, select Filter
- Ensure that the Unread filter isn't ticked
- If the Unread option is ticked, click the Clear Filter icon
- Click on the folder you are having issues with
- The folder name will be displayed above the list of emails, you need to ensure that the drop-down menu to the right of the folder name is displaying Messages
For other browsers, rather than the folder name, you will see the word View and to the right of this you find the drop-down menu that should be set to Messages.
Why do weblinks in my email messages get amended?
Exchange adds a secure redirect to web links in emails automatically. Not doing so would present a privacy risk to the end user. The secure URL also allows you to navigate away from and return to OWA without re-authenticating.
If the amended link was not added, when you clicked the unsecured link, your web browser would send the original URL as part of the HTTP referrer header. The referrer header would contain your username and the subject of the message that you where viewing at the time. By adding a secure URL, no confidential data is passed in the referrer request.
The above behaviour is by design and it is not possible to turn it off for privacy and security reasons, both for the individual and the University.
You may also see text which states that MailScanner has detected a potential fraud attempt. This message is displayed because MailScanner interprets the secure URL added by Exchange as a redirected webpage and as a result raises the potential fraud risk to the user.
Again, the MailScanner behaviour is by design and has been implemented to reduce the possibility of the recipient of the email being a victim of fraud.
Why does OWA timeout when I am using it?
This is a valuable security feature to help protect your account from unauthorized access.
There are two security options in OWA, each of which has its own timeout based on a set period of inactivity by the user:
- Public or shared computer which has a 20 minute timeout
- Private computer which has a 60 minute time out
The default option is Public or Shared computer.
Exchange 2003 classes interaction between OWA and the Exchange servers as user activity. For example, clicking on a mail folder, opening messages, saving items, moving from one folder to another or moving from email to calendar.
Exchange 2003 does not class the entering of text into OWA as user activity. For example, typing an email, meeting request, note, contact or task.
Considering the above, you should save messages every five minutes to avoid OWA from timing out. If you don't save your messages as you type them, your OWA session will time out and you will lose the text you have typed.
