We have Skype + Mattermost (without gifs) + Rainbow. Give me Teams if you want, but please, stop adding tools.
Either our mattermost is not up to date, or it has been disabled by the administrators. In any case, I have no power to do anything
We were forcibly moved from Mattermost to Teams (because cost) and the lack of custom emotes is sorely felt throughout the company. I never counted, but I wouldn't have been at all surprised if we'd had >100 of them. So many in-jokes gone forever.
