A global Microsoft outage is disrupting most workplaces and services across the north-west of England.
NHS and police services, along with airports and schools, are warning people about emails being down and finding work-around ways to help keep contact.
Greater Manchester, Lancashire, Cheshire and Merseyside Police forces have posted on their websites, saying there were issues with online forms and its live chat service, advising people to call 101 for time-critical non-emergency reports.
A spokesman for Manchester Airport said the outage had not affected any operational systems, and everything was running as normal but its corporate set-up and “minor technical processes” were affected.
The airport is using a work-around for processing domestic passengers, but this is an established process, he said.
The spokesman said if this changed, for example, if airport retailer systems were affected – then the airport would post that on social media.
The worldwide disruption began on Thursday, affecting Microsoft’s email, messaging and other online services.
Microsoft said attempts to restore services had not worked as expected, but it was continuing efforts to resolve the problems.
The company said there was no indication the disruption had been caused by a cyber-attack.
