The option to Turn Off Emojis is still in the works.
No additional details at this time.
Ben - After typing an emoji if you hit CTRL+Z it will revert to alphanumeric characters and will send as such to your recipients.
I hope that helps a bit!
There seems to be some confusion around how this works. First off the ability to delete messages is off by default.
The IT Admin who setup the Teams environment will need to turn on the admin ability to delete messages. Once they have enabled the functionality, admins will be able to delete user messages.
If your IT Admin as enabled it and you still are having troubles please let me know in the comments below.
I want to assure you that overall performance, speed, cpu, memory, etc. are all being worked upon.
We want to get these improvements to you ASAP – and so are releasing fixes as they are made, which in turn will snowball into a larger improved feel. (As opposed to holding these in earlier rings, and then doing a big bang update.)
Please know that the feature team is hard at work on dozens of items to make these improvements. We’re seeing great gains in performance in earlier rings of deployment, and you will soon see these improvements as they’re released to further rings.
Again, it won’t be a single update that’ll address all the concerns, and it will take time. But gains are steadily and surely coming.
This update is specifically targeting the Giphy selector scenario and the memory improvement is seen in that case. We have numerous memory improvements in the works which all work to improve the overall memory usage. Unfortunately I don't have any details I can share at this time. However, I will post more updates as soon as I am able.
