I purchased Microsoft 365 E3 Enterprise for our company team, and the license key worked perfectly once received. There was a short delay of a few hours before delivery, but support responded professionally and reassured us. After activation, everything functioned smoothly including Teams and admin controls.
Works fine. Slightly longer than expected.
Works perfectly. Will buy again.
Had a small issue but support helped.
Activated on first try. Very happy.
