Set Compression for Email Attachments when the report exceeds in size

There is an option in Cognos Administration to set compression for email attachments when the report size exceeds a particular limit.

This is often helpful in the case of Active reports where the mht file size tends to increase over a particular limit and cannot be send by email.

In IBM Cognos Business Intelligence, you can choose to compress email attachments above a specific size, or disable compression. By default, compression is disabled. If you want email attachments compressed, change the default behavior using the configuration setting, Maximum size of an uncompressed email attachment in MB.

An email attachment must be at least 1MB to be compressed.
