There is no legal limit to emails.
Each mailbox is limited to 400MBs in total.If your mailbox has reached its 400MBs limited you will no longer receive emails and emails will start to bounce back to the sender.You will receive an email stating that your mailbox is near is maximum size limit. When receiving this email YOU will have to delete emails from our server by the webmail interface.
E-mails may not be larger than 25mb (megabytes). Thunder bird does not appear to limit any number of attachments. They can be received and stored at the same time.
you can send at least 100
All mail servers have a limit of space for emails. Your email server has the limit about 1.82 Gb. To prevent deleting new emails you have clean your email. Delete all letters which you don't need, or save letters at another place than Outlook base which you need and after that delete it. You might have to log on directly on mail server and delete from the server. Usually if you are using Outlook you don't need to do that.
