When we create a mailbox, we get postmaster mailbox too, how we can delete it or change its quota ?

You get Postmaster mailbox for free and you can neither delete it nor change its quota. Webmaster is a regular mailbox and it counts towards your total maiboxes.

Hi,

With due respect to the members, I just want to ask whether can i change the mail quota and how ?

Regards,

Welcome Mub,

For each of your mailboxes you get some default amount of disk space for storing incoming and outgoing mail. Load statistics for each of your mailbox can be found in the Properties section for every individual mailbox.
It shows how much disk space you are using out of your mailbox quota. You can’t store more MBs than your mailbox quota allows. You can change your mailbox quota, by clicking the Change icon next to the statistics readings for each individual mailbox.
– recurrent fee for the days that remain to the end of the current billing period is refunded.
– you are charged the recurrent fee of increased mailbox quota prorated to the rest of the billing period.
Please, take care that your hosting plan may be configured to prevent you from setting very high mailbox quota.

I do want store more MBs than my mailbox quota allows?

But, you can’t store more MBs than your mailbox quota allows.
