You can send a ZRS infoview report URL through e-mail to any user who has credentials to view those reports.
The following steps explain how to identify the url for each report in your ZRS.
https://<Server Name>/OpenDocument/opendoc/openDocument.jsp?iDocID=<DOC ID>&sIDType=CUID&sType=wid&sRefresh=N&sWindow=Same
<Servername>: The host name in which your ZRS is running.
<DOC Id>: Right click on the report and select Properties.
The Doc id is the CUID mentioned in that page.
See image below to identify the CUID.
Note: The above tip is applicable only for ZRS 10.3.
With the 10.3 release a report linking based bug is fixed.
