What is the maximum size of sending an email?

For Office 365.

Question:

What is the maximum size of sending an email?

Answer:

On the Office 365 environment with the HENNGE One service, you can send an email that is approximately 25MB.

The Office 365 service can send/receive emails up to 25 MB by default, but the setting can be changed to 150 MB. 

However, if a user sends a large email, it will take time to process the email on our service and
it may not be received on the recipient side due to its size limit.

Therefore our service provides an environment where a 25 MB email can be sent by taking into account the Office365 default setting
and general business circumstances.
(If a user sends a larger email, there will be a delivery error)
