Apple's MobileMe migration continues to be troublesome, with the company last night confirming at least some problems that could be attributed to one of the MobileMe email servers.

In a note distributed last night, the company admits: "On Friday, July 18, 2008 (2008-07-18) we experienced a serious issue with one of our MobileMe mail servers. This issue is currently affecting approximately 1% of MobileMe members. Affected members are unable to send or receive email at www.me.com or access email using any email client software such as Mail on a Mac or Microsoft Outlook on a PC."

The company - which recently offered 30-day extensions on the period paid for by existing subscribers to compensate for the seriously troublesome migration - has also been forced to apologise for this all-new problem.

"We understand this is a serious issue and apologize for this service interruption. We are working hard to restore your service," the company informs.

The company claims all other MobileMe services are functional, but complaints continue to emerge from service users.
