Abstract

An office information system having a plurality of work stations connected via a network to mutually exchange electronic mails each includes a control information definition unit for defining control information representing what kind of processing can be performed on mails after reception, a processing log memory unit for storing log information of operations which have been performed on a received mail, a control unit for guiding a receiver by referring to both the control information and log information, a task tracking instruction unit for inquiring the processing status of mail, and a task tracking unit for reporting the status in response to such a tracking instruction. The system stores and interprets control information relating to the flow of an OA object on the network, which has been conventionally involved in the memory of an office worker, and guides the office worker to work to be done by the office worker. As a result, a chance for the OA object to stagnate at a certain location is reduced, and the circulation of OA objects on the network is totally improved.

Claims

1. A server connected to a plurality of clients via a network over which each client sends and receives electronic mail, said server comprising:

defining means for defining and storing control information including a schedule of when electronic mail is expected to be received by a receiving client; and

control means for prompting, based on said control information, a scheduled sending client to send electronic mail which has not been received by a predetermined deadline for receiving said electronic mail.

2. A server connected to a plurality of clients via a network over which each client sends and receives electronic mail, said server comprising:

means for defining and storing control information specifying actions for said electronic mail to be conducted by each different authorized user in each receiving client;

means for storing information of an operation log containing an action for the electronic mail conducted by the authorized user of each receiving client;

task tracking means for tracking a process condition of the electronic mail on the basis of said operation log; and

changing means for changing process contents for the mail included in said control information on the basis of a result of execution of said task tracking means.

3. A server connected to a plurality of clients via a network over which each client sends and receives electronic mail, said server comprising:

defining means for defining and storing control information specifying actions for said electronic mail to be conducted by each different authorized user in each receiving client;

means for storing information of an operation log containing an action for the electronic mail conducted by the authorized user of each receiving client;

task tracking means for tracking a process condition of the electronic mail on the basis of said operation log;

changing means for changing a mail route included in said control information on the basis of a result of execution of said task tracking means; and

storing means for storing information of an operation log containing an action for the electronic mail conducted by the authorized user of each receiving client;

task tracking means for tracking a process condition of the electronic mail on the basis of said operation log;

changing means for changing process contents and a mail route included in said control information on the basis of a result of execution of said task tracking means; and

sending means for sending the electronic mail on the basis of said changed electronic mail route.

5. A server connected to a plurality of clients via a network over which each client sends and receives electronic mail, said server comprising:

defining means for defining and storing control information specifying actions for said electronic mail; and

control means, responsive to a change of said control information changed by a receiving client while forwarding the electronic mail, for reporting changed contents of said control information to a sending client for the electronic mail.

6. A server connected to a plurality of clients via a network over which each client sends and receives electronic mail, said server comprising:

defining means for defining and storing control information specifying actions for said electronic mail to be received by a receiving client;
