Microsoft is ditching Electron for Teams

If you work in an enterprise environment where the microsoft domains are whitelisted, but cdn.office.net is not...you'll end up with a couple hundred requests per second because it keeps trying to refresh all emojis, folder icons and others in an endless loop.

I'm not kidding you. They DDoS themselves because the app apparently doesn't cache anything.

Oh, and don't try what happens when skype.com doesn't work. The whole app goes maniac then.

cdn.office.net is fully, unrestrictedly accessible.

Also, I believe those re-authentications are actually ALL the app is doing in those moments.

It's not actually loading anything, not emojis, not notifications or anything else (all of the app still works normally) - it's just re-authenticating, re-authenticating, re-authenticating, re-authenticating... in the background (eating quite a bit of CPU and bandwidth in the process).

> domains are whitelisted

Why people still do that?

Microsoft doesn’t publish an accurate list of IP ranges, and pushes many things to Akamai, so you need to whitelist a few dozen domains.

When I ran a very large O365 environment, it was even harder as we had a dedicated 10Gb circuit to Microsofts network, and and depending on various bugs, conditions, etc, you could easily send traffic to the wrong place and impact performance. (For example, if you inspect TLS traffic, that latency will kill Outlook application performance)
