Daxa Baxi International Tax Advisor — My MTNL email size

Address:	122 Poornanand , Dongersi Road Walkeshwar
Website:	MTNL.net.in

I have been using MTNL email address for the last 20 + years. I am finding that the mail box is too small. Is there a way to increase the size? If I cannot increase the size, I will be forced to subscribe to other emails such as personalised gmail. I appreciate that these are paid services. I am willing to pay to MTNL, provided I get similar service from MTNL.
