Like most email systems, Kundo has size limits for incoming and outgoing emails. These limits are set by the third-party systems we use and unfortunately cannot be changed on our end.

However, with our Microsoft 365 integration, you can configure these limits yourself, giving you greater control and flexibility over your email flows.

Outgoing emails

• Maximum total size (including attachments): 24 MB

• Maximum size per individual attachment: 17 MB

Incoming emails

• Maximum total size: 40 MB

• There is no separate limit for individual attachments – only the full email size matters.

• This limit can also be adjusted via the Microsoft 365 integration.
