that some iOS devices are overloading Exchange servers after being
updated to iOS 6.1, Apple has now promised a fix and has said that it
will be including the fix in a future software update.
In a support
article, Apple has acknowledged the
problem saying that if an Exchange user responds to an exception to a
recurring Calendar event with a Microsoft Exchange account on a device
running iOS 6.1, the device may begin to generate excessive
communication with Microsoft Exchange Server, resulting in increased
network activity or reduced battery life on the iOS device and that the
extra network activity will also show up in the logs on Exchange Server,
leading to the server blocking the iOS device.
Apple has advised
that users can avoid this bug by not responding to an exception (change
to a single instance of a repeating calendar event) to a recurring event
on their iOS device, until a patch is issued. It has also recommended
that users can turn off Calendars from their Exchange account for a
period of 10 seconds and turn them back on if they do respond to an
exception and encounter the bug.
Earlier, Microsoft had also
issued a support document advising
administrators and users to not process Calendar items such as meeting
requests on iOS 6.1 devices, and to immediately restart the iOS 6.1
device. It had also recommended removal and reactivation of the device
partnership with the server, creating a custom throttling policy for
iOS 6.1 users, and blocking iOS 6.1 users on the server.
released iOS 6.1 on January 28.
The update added LTE support for various carries around the world and,
for users in the US, the ability to purchase movie tickets through
Fandango with Siri. Other new features included a new option to reset
the Advertising identifier and offering iTunes Match subscribers the
ability to download individual songs to their iOS devices. Also included
were redesigned playback controls on the lockscreen, minor changes in
Safari and slight changes to boarding passes in Apple's Passbook
