APM ActiveSync Limit

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.

Increasing the APM limit for ActiveSync email POST body

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