Aliases must remain static until switchover
MobileMe email aliases must remain static until the fall, an Apple support document states. Until that time, aliases can no longer be added or deleted, set as active or inactive, or even have their colors or descriptions changed. Although actually sending and receiving email continues to work, the ability to modify the aliases will only be restored once MobileMe users start migrating to iCloud in the fall.
During yesterday's keynote presentation Apple CEO Steve Jobs openly downplayed MobileMe, remarking that it wasn't the company's "finest hour." iCloud will replace the older service, and to that end Apple has set a firm switchover deadline at the end of June next year. Developers are already receiving instructions on how to safely transfer data such as calendars.
