Mails box quota

Jordane 1

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

Hi @Jordane ，

Welcome to Q&A forum.

Please understand under Outlook tag, we mainly focus on general issues on Outlook desktop client, considering your issue may be more related to exchange, in order to solve it better, I added office-exchange-server-administration tag under your post, thanks for your understanding and hope your issue would be resolved soon.

Hi @Jordane ,

What't the version of your Exchange server?
Do you mean you have checked the mailbox usage of some problematic users via ECP and verified they still have a lot of space in the mailbox?

They have notification about mail has failed to be sent. For quota reason.

If possible, could you remove all sensitive information like email address, domain name, etc. , and then share a screenshot of the notification so that we can learn better about the situation?

Hi @Jordane ,

It is exactly like you show.

If that is the case, seems to me that it's likely the issue is not related to the user's mailbox quota. Below is what the user see when the mailbox's send/receive quota is exceeded:

And this is what I see in EAC:

Supposing the above is not your users are encountering, could you try sharing "the notification about mail has failed to be sent" so we can do further analysis on this? For privacy concerns, you can remove all personal information involved, just share the general error message.
