They say it has left them unable to access bank accounts and job offers - and stopped them using Skype, which Microsoft owns, to contact relatives in war-torn Gaza.
Microsoft says they violated its terms of service - a claim they dispute.
“They killed my life online,” said Eiad Hametto, who lives in Saudi Arabia.
“They’ve suspended my email account that I’ve had for nearly 20 years - It was connected to all my work,” he told the BBC.
He also said being cut off from Skype was a huge blow for his family.
The internet is frequently disrupted or switched off there because of the Israeli military campaign - and standard international calls are very expensive.
Israel launched its offensive in Gaza in response to the Hamas attack on 7 October, which killed about 1,200 people. The Hamas-run health ministry in Gaza says more than 38,000 people have been killed in the war.
That I really couldn’t say, only a few weeks in on emails that were not being used before, so not really getting “unsolicited spam”.
I am getting a lot of messages related changing my accounts over.
Their spam filter is configurable though:
They also have complex filters you can set up to either auto-label, or auto-sort non-spam into folders, from basic usage, up to complex regular expressions; depending on your level of dedication.
All I set up for now is an auto-filter any email with ‘unsubscribe’ somewhere in the body to be sent to an ‘subscriptions’ folder. I will get around to it more eventually.
I’m currently on the last 2 days of a free 30 day trial. I’m going to do annual pay for their family plan though, so I’m sticking with them.
