BlackBerry users in North America are experiencing email outages after an unspecified problem from maker Research in Motion.

Service has been down from some customers since about 3:15 a.m. Thursday.

Only those users with individual plans appear to be affected. Those under corporate plans appear to be receiving email as usual.

In an email statement to CTV.ca, a RIM spokesperson said customers are experiencing delays in receiving email, and technical teams are working to resolve the issue.

The statement said phone service, browsing and PIN-to-PIN messaging are working as usual.

Rogers Wireless says it was informed by Waterloo, Ont.-based RIM that this is an unspecified network problem that is affecting multiple wireless carriers in the Americas.

"Blackberry Internet service subscribers may be unable to send or receive messages view email attachments, or request to see more text," Odette Coleman, Rogers' Director of Communications told CTV.ca.

Coleman said RIM has not said how long the outage could last, but that Rogers has asked "for a resolution as soon as possible."

She said it is unclear how many Rogers customers are affected.
