I'm in the process of migration users to a new Exchange server, I have based the migration priority based on the user's mailbox size. Now I can easily get all mailbox sizes using EMS but something caught my eye and was wondering how to go about adding\changing an attribute.
So logging into EAC you automatically land on 'Recipients / Mailboxes' here you can add and remove the required columns you need. But there are also 15 custom attributes. From what I have read so far you can customize these to whatever you need (I think).
Well I want to be able to see user mailbox sizes in EAC and I recon this can be done by editing/adding a custom attribute, but the question is HOW?
I know I can edit a user and add n custom attribute there, but that just seems like an additional label you can add.
How can I go about changing an attribute to get mailbox statistics for my users?
