OWA (Outlook Web App): Browser e-mail

Outlook Web App (OWA) is an email application used in a browser. The university's Office 365 e-mail service contains two separate systems: local e-mail and cloud e-mail. As a default, everyone at the university uses the cloud e-mail. Some tasks may prevent the use of cloud e mail. In such special cases, the user's e-mails are stored on the local server. Contact the Helpdesk for further information.

Which Office 365 system is my mailbox located in?

There are so many variables in the login that detailed step-by-step instructions cannot be given. Here are a few tips on how to get started, however. Try and find your own way to work. The first login is different from future logins as some basic settings are set when you log in the first time.

If the browser is working strangely and these instructions don't seem to help, clear the browser's cache.

See Detailed help tab for more instructions

Microsoft updates Office 365 services sporadically, thus functional and layout changes can occur. Therefore there can be discrepancies between these instructions and your updated version. Please use the feedback link at the bottom of this page in case you notice any significant discrepancies.

Cloud e-mail on a university computer

Address of the service

When you have logged in on a university computer using your username, you can access the cloud e-mail directly at https://www.helsinki.fi/office365. This means that you cannot log out of e-mail, such as from Webmail. You will stay logged in as long as you are logged in on the computer.

You can read your email on a computer used by someone else by temporarily switching users (Switch user). When someone else is logged on to the computer, you cannot log in to your own e-mail as the computer uses the information of the person who logged in first, opening their e-mail even if you try to log in using your own username. Read the instructions on how to log in.

Cloud e-mail on a home computer

You can log into cloud e-mail directly at https://www.helsinki.fi/office365.

When you are using a home computer, you need to log in at stshy.itx.helsinki.fi using your own username. See below for further information.

Local e-mail on a university computer

You can use the local e-mail system at https://office365.helsinki.fi. A login window will open.

  • Enter your username and password.
  • We recommend selecting (1). When using staff computers, the selection allows the user to stay logged in, even during longer breaks.
  • By selecting (2), you can log in to OWA light. OWA light has limited functionality compared to the full version, but it might be the only option for some browsers, operating systems and slow connections.

Local e-mail on a home computer

Local e-mail on your home computer works just like the above described e-mail on a university computer, but logging in may contain another step for the server stshy.itx.helsinki.fi. See below for further information.

First login

The use of OWA is similar inside and outside the university network, but more steps might be required for logging in to OWA outside the university network.

At the first login, the application asks you to select some basic settings:

  • Choose your language and time zone.

  • The browser may ask you if you want to save data to your computer. Answer Allow.

You can access your e-mail after selecting the basic settings.

  • Use the AppLauncher icon in the top left corner of the window to find links to the available applications.

You can change the settings later following these instructions.

Opening OWA from a bookmark

Opening OWA from the bookmarks

  • When you open OWA from the bookmarks, does the Microsoft login window appear? Enter your username in format username@ad.helsinki.fi. Click Next.
  • Type your username in the long format username@ad.helsinki.fi, and your password.
  • Click Sign in.
