Applications on TCIT Gateway Collection 1
Applications on TCITGateway Collection 1 have been updated as of June 2022. The biggest change is Microsoft Office 365 has been installed.
When you go to open an Office program, you will be prompted to sign in to Microsoft 365 applications (such as Outlook and Word) and Microsoft Teams.
- The sign-in prompt will default to using “username@sattrn.ou.edu” as shown below, but that username cannot be used to log in. Instead, click “Use another account or sign up,” and then enter your OU or DHS login for Office 365 and continue signing in.

When you try to open an Office application, you might get an error message saying, “Sorry, another account from your organization is already signed in.” To resolve this:
- Sign out of Microsoft Teams and close it.
- Reopen any Office application and sign in there.
- Please contact TCSupport if this does not work, or if you need assistance. This experience may vary depending on your existing settings.
For several users, we have found they also needed to sign out of Microsoft Office, so here are the steps to resolve this issue:
- Open Teams in TCITGateway. Select your profile icon (this may be your profile image or your initials) in the upper right and sign out. Close Teams after signing out.
- Open any Office application like Microsoft Word. Click “Account” in the lower left (see screenshot below) and sign out. Close the application after signing out.
- Reopen any Office application. You should get the login prompt immediately. Sign in there.

MS Visio and MS Project have also been installed with this update; however, you will only be able to use them if they are included in the license assigned to your Office 365 account. You will receive an error message saying “Account Issue” if your license does not support these apps. TCSupport can help you get a license that includes these apps if you need them.
In addition to Microsoft 365 being installed, several Adobe applications and Articulate 360 have been updated.
