# Introduction
`SBP` is a command introduced with [MSNP10](../versions/msnp10.md).

It is a Notification Server command, without a request or response payload.

Sets a buddy's property in your cache to a specified value.
For the command this replaced, read [REA](rea.md).

# Client/Request
`SBP TrID contact-id property value`

Where `contact-id` is the `C=` value from either [ADD](add.md) or [LST](lst.md).
If you are using `ABCHMigrated: 0`, this is the contact's user handle.
If you are instead using `ABCHMigrated: 1`, this is the contact's GUID.

Where `property` are any of the values:
* `MFN`: My Friendly Name
* `MOB`: User can contact me via MSN Mobile, changed by the Client Capability.
* `WWE`: User can contact me via MSN Direct, changed by the Client Capability.
* `HSB`: [MSNP11](../versions/msnp11.md)+: Has blog, changed by the Client Capability.

Where `value` is the URL-encoded value to set the related `property` to.

# Server/Response
`SBP TrID contact-id property value`

Same parameters as the request.
