Microsoft Teams already generates a ton of data(down to reactions on messages) that you can see in the Entra activity log. I guess this is aimed more at Slack, etc. which I am sure already has plenty of logs somewhere.

This does nothing to address the out-of-band channels. Most of my working peers will use Signal or other applications to communicate off the record so this is mostly window dressing.

On a somewhat related note, it's my opinion that Slack could be using private DMs for advertising purposes. My friends and I were skeptical at first after they started getting ads in Instagram/FB and other platforms immediately after we'd mention a product. We figured it was coming from another source. We then started testing it by mentioning products in our private chats that we'd never searched or talked about elsewhere (Fish Food for example, none of us have pet fish). Lo and behold we'd start getting ads for them.

The press release does mention Signal explicitly, so I guess companies need to enable message backups for it.

If the corporation does not explicitly state that Signal is an acceptable chat tool, but Signal can be successfully used, is the corporation responsible for messages passed by an employee over Signal?

Where I work, using signal or any other tool for something related to work is a fireable offense.

If you want something OTR, it's either a phone call or a f2f.
