Facilitating cross-organization communications

A method comprising:

• receiving, from a first computing device associated with a first user, a request to generate an invitation for enabling the first user to communicate with a second user of an outside organization via a shared communication channel of a communication platform wherein the invitation is accessible to the second user via a second computing device;
• receiving, from the second computing device, acceptance of the invitation to communicate with the first user via the communication platform based at least in part on an identifier associated with the invitation;
• and
• based at least in part on the acceptance from the second computing device, generating the shared communication channel between the first user and the second user, wherein an instance of the shared communication channel is displayed in an interface of the outside organization as a shared channel, wherein the shared communication channel enables communications to be transmitted between the first computing device and the second computing device via the communication platform.

One or more non-transitory computer readable media storing computer-executable instructions that, when executed by one or more processors of a computing device, cause the computing device to perform operations comprising:

• receiving, from a first computing device associated with a first user, a request to generate an invitation for enabling the first user to communicate with a second user of an outside organization via a shared communication channel of a communication platform wherein the invitation is accessible to the second user via a second computing device;
• receiving, from the second computing device, acceptance of the invitation to communicate with the first user via the communication platform based at least in part on an identifier associated with the invitation;
• and
• based at least in part on the acceptance from the second computing device, generating the shared communication channel between the first user and the second user, wherein an instance of the shared communication channel is displayed in an interface of the outside organization as a shared channel, wherein the shared communication channel enables communications to be transmitted between the first computing device and the second computing device via the communication platform.
