473:. To ensure that all messages are delivered in a reasonable time on a network where machines might appear and disappear at random (when they are turned on and off), AOCE has a 15-minute timeout in which it repeatedly tries to deliver pending messages. If the user is using a dialup connection on a modem, AOCE keeps the line open for a full 15 minutes before giving up on disconnected user, driving up long distance bills to deliver a potentially tiny message.

While newer machines were able to run AOCE more comfortably, as an email system intended to be run on diverse networks of heterogeneous machines the requirements greatly impaired market acceptance. Simply downloading and installing separate stand-alone client applications for each mail system the user actually had would use considerably less disk space, and had no constant

Although a single-mailbox system could be constructed by administrators with the use of email gateways, these tended to be expensive and technically challenging to maintain.

maintenance. The server was not ready in time for the release, and did not ship for another year. When it did it was likewise slow and resource hungry, largely a side effect of various features of the Mac OS that makes it unsuitable for server applications—a role for which it was never designed in the first place.
566:. The book documenting the system is larger than all of the books describing the rest of the pre-System 7 Macintosh combined. Adding a simple feature like "mail this document" to an application requires wading through hundreds of pages of documentation, and writing a core AOCE component is many times more complex.

By early 1993 the client side of AOCE was nearing completion, which was then referred to as PowerTalk. Apple started a pre-release marketing campaign, telling larger customers and even third party email vendors that AOCE would soon arrive and change the market completely. Their claim was that nothing

Several parts of the AOCE engine are useful on their own, such as the

When the product finally shipped after years of hype, users were dismayed to find that to install it requires a machine with 2.5 MB of RAM minimum, and needed 4 MB to run well. This is the maximum available RAM in many Mac systems of the era. Removing unneeded components do little to address this,

An optional server can be installed for performance and maintenance needs for those sites that required it. In this case any attempted delivery would be intercepted immediately by the server, thereby avoiding delays if the recipient was not online. The server then delivers the message on behalf of

At one end of the system, AOCE focuses on the underlying delivery and addressing systems, generalizing the email concept so the system can be used to deliver anything from email to word processor documents to print jobs. Addressing was another issue the market was struggling with, so AOCE offers a

While PowerTalk was generally an interesting system, a combination of design features made it frustrating to use. For instance, the addressing system is so deeply embedded into the core of the system that simply typing in a new address is an ordeal. First the user clicks on a button, selects the

AOCE and PowerTalk were heavily marketed between 1993 and 1996, but the hardware requirements meant that most users couldn't even install or use it. Developers were likewise stymied by the complex system, and since the installed base was so small their potential sales were even smaller. In 1996,

The system could not know who a user was, because the single-user Mac OS 7 does not require users to log in. Thus documents had to be delivered to a user's machine. This does not work well when the user has two or more machines, making the concept of a universal mailbox difficult to achieve in

Many of these problems were intended to be solved with the PowerShare server, which acts as an always-on, always responsive super-peer. The basic AOCE protocol notices these machines when attempting delivery, and sends to them first, thereby eliminating the delays and centralizing storage and
