Message limitations

There are certain limitations in place for each message that is sent on Symphony. These limitations are detailed below and only apply to the Symphony Desktop Application (SDA) or browser version.
  • The current limitation for a message is a maximum of 30,000 characters.
  • This includes no more than 40 tags in the same message.
  • The limit for @mentions is 40 in the same message.

Attachments have their own set of limitations.
