Hello,
I am managing 14k user in a new project.
I m beginer in exchange administration.
I have almost have full rights on the server.
À lot of my user have quota problem they cannot send or receive any mail. They have notification about mail has failed to be sent. For quota reason.
If i check my ecp admin console. They are for some of them arround 10% or 25% of 25go, so i dont understand what is happening any idea on where to investigate are welcome. I tried nothing yet.
Édit : I forgot to say this is after a migration project.
Thanks before
