A computing device includes a processor and associated memory. The processor is configured to execute a personal information management service stored in memory to send a first calendar entry for display on a calendar interface for a user. The first calendar entry is for a first account of the user of a first domain. The processor sends a second calendar entry for display on the calendar interface. The second calendar entry is for a calendar of a second account of the user of a second domain. The processor receives a request for an availability of the user from a requesting user having a third account of the first domain. In response to the request, the processor sends to the requesting user the first calendar entry including first calendar entry details, and the second calendar entry without second calendar entry details.
