This document covers the following topics:
Undo addressees of a mail item, including invitations to a meeting.
If none of the addressees has read the mail item, you can undo the whole mail item. In this case, it is not required to specify the parameter Address-index.
If the mail item has already been read by one of the addressees, you can only remove an addressee who has not yet read the mail item. In this case, you have to specify the addressee to be undone in the parameter Address-index. For example, to undo the 7th addressee, specify "7" in the parameter Address-index.
If you want to undo mail to all addressees who have not yet read the mail item, specify "-1" in the parameter Address-index.
You cannot undo the whole mail item, if it has been sent to an external addressee (e.g. SNADS).
When repeated delivery has been specified for a mail item, an X is returned in the parameter Repeated-delivery. This means that the counter for repeated delivery has been reset to zero. The addressees, however, have not yet been undone. In this case, you have to invoke Z-UNDO once more to undo the addressees.
When the sent mail item has not been undone completely (i.e. if there are still addressees who have received the mail item), an X is returned in the parameter Sent.
The return code 93 indicates that more than 500 Adabas calls were made and some addressees could not be undone. In this case, the user should execute any program providing screen input/output to prevent the NAT3009 error in online mode.
