How can I find out a mailbox quota?

To find out the current mailbox capacity (mailbox quota), log in to webmail at In the top menu, click on the button with the mailbox name.


The menu contains information about the capacity of the mailbox, the capacity of the web storage and the free space in the Dropbox storage (if your Dropbox disk is connected).

If you select Settings in the top menu, you can find out not only if the mailbox is full, but also information about the attachment size of your mailbox in the Information section.
