ARCHIVED: File types that cannot be transferred through UniCom

This content has been archived, and is no longer maintained by Indiana University. Information here may no longer be accurate, and links may no longer be available or reliable.

Use Microsoft Skype for Business to access Indiana University's UniCom service.

Note:

Office telephone service for faculty and staff at Indiana University has transitioned from Skype for Business to Teams Calls.

In Indiana University's UniCom service, you can send files in individual instant messaging (IM) conversations using Skype for Business. However, to protect the computers at IU, UITS has enabled filters for attachments that have been known to carry viruses.

To send any of these file types in an instant message, rename the file, using either a different extension or no extension. Notify your recipients of the original file type so that they can rename the file's extension before opening it. (This assumes you can see file extensions.)

For help, see Microsoft Support.

The UniCom filters block the following file types:
