Overview: Supporting larger email attachments for ActiveSync

By default Access Policy Manager® (APM®) supports a POST body of up to 64 KB for ActiveSync. If an email body exceeds that limit, APM writes a message, ERR_NOT_SUPPORTED, to the var/log/apm log file. APM can be configured to support a POST body of up to 25 MB.

You can specify the supported size for the ActiveSync email POST body using a database variable.
Note: The maximum supported size is 25 MB.
