Users react to ongoing Microsoft outage
Affected users took to X to express their frustration about the ongoing outage.
A user wrote, "Happening on Steam as well, launched the game and tried to link it to the MS account and after putting in the code and hitting allow access it then prompts to enter email and sign in. Then error 400 upon signing in."
Another user wrote, "Can’t save my word doc because Microsoft servers are apparently busy and can’t access onedrive. Have to try to force the computer to save work to it’s memory so I can actually save/access it."
"Instantly get a infobox in word telling me off for daring to not save online to onedrive," a user added.
