A new single-click button will mean workers can report dodgy emails directly to the National Cyber Security Centre (NCSC), in a bid to clamp down on cyber crime.
People could already forward scams to the NCSC's Suspicious Email Reporting Service (SERS), but it is hoped the ease of a single button will encourage more widespread use according to a report from Sky News.
Cyber crime has cost organisations more than £5m in the past 13 months.
Among the most common types of phishing seen are employees being tricked into downloading malware that looks like it comes from IT support, clone login pages stealing personal details, and emails containing fake alerts from common workplace software.
Dr Ian Levy, the NCSC's technical director, said: "The pandemic has shown the cybercriminals will stop at nothing to attack and defraud citizens and businesses.
"But our Suspicious Email Reporting Service has also shown that the British public can help us fight back against this scourge.
"This new reporting button makes it easy for businesses using Microsoft 365 to enable their staff to report dodgy looking emails and further help combat cyber crime.
"As more people report more dodgy stuff to us, the safer everyone gets."
In July, the average case reported to the NCSC took four hours to be removed.
"Sadly, criminals will use every opportunity they can to trick people into handing over their personal and financial details," said Clinton Blackburn, Temporary Commander of the City of London Police. "Phishing messages provide criminals with a gateway to obtain this information, which they will then use to commit fraud."
