Messaging in 8x8 Work Applications FAQ

How do I share files via messaging?


For Team Messaging:

  • Filesize limit: 100MB or less
  • Filetype: Any

For SMS/MMS to other carriers the MMS Operator Specific Policy is: 

  • Filesize limit: 2MB or less
  • Filetype: Audio and Video files only


Click + to select one or more files (please see note above), then type an optional message to include with the files, and press Send (paper airplane icon).

What message format commands are available?

Bold, italics, strikeout, fixed-width font, and hyperlink text. Click here to learn how to format text!

Can I send messages to a contact's internal extension as well as their external mobile phone number?

Yes. There will be two conversations shown in your Messages list so that you can respond via SMS or internal messaging.

Can I delete sent messages?

You are only able to delete IM (not SMS) messages that you send.  Click on the 3 dots icon next to the message and select the "Delete" option.  Note that currently, you are only able to delete messages that were sent within 12 hours.  After that, the "Delete" option will still be available but will not be responsive when confirming.

What happens to message history if I unassign an extension in Account Manager?

Chat data is tied to the user account ID instead of the extension, so messaging history will not be available when reusing extensions. To retain the messages for an account, the user account ID must be reused and not deleted.

What happened to my sent SMS history from March 2018 and earlier?

SMS history is only available from April 2018, when a new 8x8 messaging platform was introduced. 

To access older SMS conversations, log in to Work for Web in a browser to see complete history.

I have a single login and use many extensions. What are the steps I need to take to use New Messaging Experience?

The 8x8 messaging service and X Series products are based around a single extension per login, so you may encounter missed messages, lack of history, and presence issues if you use a single login and multiple extensions. Please set up each extension you use as a separate login for the best user experience.

If I create a new login account for messaging, will it have history from the extension that was previously assigned to it?

No, it will begin with no history as of the creation date, but accumulate all new messages as history.

Is there a group chat feature?

Yes! Check out 8x8 Team Messaging here.
