Research In Motion's Blackberry users in North America suffered another outage with their e-mail service, just a week after another outage hit the company.

Late Tuesday night, RIM confirmed that its BlackBerry service had suffered its second e-mail outage in five days.

Some Blackberry customers in the Americas are currently experiencing delays in message delivery, RIM said in a statement. However, Blackberry users in many parts of Asia including China, South Korea, Australia, Taiwan, India and Singapore, have also reported problems.

Users were unable to receive messages or chat via BlackBerry Messenger, though calling and texting functions were unaffected.

The outage hit Blackberry services offered by numerous carriers, including Sprint Nextel, AT&T, Verizon Wireless, and Canada's Rogers.

The “root cause is currently under review, but based on preliminary analysis, it currently appears that the issue stemmed from a flaw in two recently released versions of BlackBerry Messenger (versions 5.0.0.55 and 5.0.0.56) that caused an unanticipated database issue within the BlackBerry infrastructure, according to RIM.

RIM has taken corrective action to restore service.

The Canadian company has been doing well and reported last week better than expected sales of Blackberry’s, but this could all change if its email service starts getting a reputation for being unreliable.
