Regarding the question of paying for and free of charge for purchasing corporate mailboxes, it mainly depends on your company's usage and budget.
Take Tencent's corporate email as an example. It has a free version and a paid version.
Free version of enterprise mailbox, free version of mailbox capacity is limited, up to 200 users, and the price is single from the use function.
If your company has more than 200 employees and needs more email functions, it is recommended that you buy a paid version with sufficient budget. The paid version has free email capacity, and the number of users will have different tariff packages according to your needs. In addition, it is rich in functions. It has many characteristics of enterprise mailbox, and at the same time continues some functions of /QQ/ personal mailbox, such as file transfer station function, and has unique functions, such as binding and call reminder.
Thank you, hope to adopt.
