How to check mailbox size in Office 365
The default size of Office 365 mailboxes varies based on the mailbox type and user subscription. The default size of a user mailbox is either 50 GB or 100 GB, and when the space is exhausted, users won't be able to send or receive emails. To avoid this, admins need to keep a check on the mailbox size.
The Mailbox Usage report provided by the Admin Center shows only the storage space consumed by user mailboxes. To view the actual user mailbox size, shared mailbox size, resource mailbox usage, and other mailbox related details you have to navigate to the Exchange Admin Center (EAC).
