Microsoft says that a recent zero-day flaw has been patched in 92% of servers. But Leo says that doesn't mean that a bad guy hasn't gotten into the system before it was patched. So they could still be compromised.
In an unprecedented move by a Chinese National Hacking Group, called Hafnium, hundreds of thousands of Exchange servers have been compromised, with over 30,000 accounts hacked this week. Leo says it's worse than that Russian Solar Winds attack. The hack takes advantage of a quartette of "zero-day exploits" that take advantage of bugs in Microsoft's Exchange email servers. Microsoft has put out an emergency update to plug the holes, and users are advised to install the fix immediately.
Clean up or edit the accounts on your iPhone (iOS 13) by looking under Settings > Passwords & Accounts. This allows you to see what accounts reside on your iPhone, such as iCloud and Gmail. You can add new ones or delete accounts that you don't need anymore. If you have a malfunctioning auto-login process, such as one your workplace set up for you, you may want to delete the account and re-add it after consulting your IT coworkers. Random pop-up error messages can get quite annoying, after all.
After the latest iOS 13 update, he gets an incorrect exchange password error. Leo says that Exchange is a Microsoft business email account. Go to Settings. Passwords and Accounts. Look and see if there's an Exchange account listed. If it is, the choice is to reconnect or delete it.
Terry got a new Mac for an early Christmas present and is waiting awhile to reinstall stuff. Leo says that's a good idea. It's much better to only install new programs as needed. Every program he installs is a potential security risk, so he should install as little as possible.
Brian is having trouble syncing to Outlook on his laptop, iPhone, and iPad. Leo suggests going into iOS settings and removing the Outlook sync account. He could also install the Outlook app.
It could also be an issue with his Exchange server at work, especially if other coworkers are having issues. He should use Microsoft's app on the laptop. Then remove the Exchange server from iOS devices and reinstall it. It's likely a network issue with work. Brian should talk to his IT guys, as they may have to configure it.
Don wants to know what Leo thinks about Microsoft Office 365. Leo says it's a great idea, and he uses it. It's for a cheap monthly fee, especially for non profits. Leo says to go for it. He can install up to five copies and get access to his files on any platform anywhere thanks to its web-based interface.
Tim's company uses Outlook and he'd like to have everyone share files and calendars without setting up an Exchange server. Is Google the best option? Leo says that it may be.
Rob is having an issue with his computer hanging only while Microsoft Outlook is open. Outlook displays his Exchange and Gmail accounts. He's tried several things, including running Outlook in Safe Mode, disabling his antivirus, and turning off add-ons. Leo says to look at the connection as it syncs. He should try changing the polling times. It also goes through the messages and indexes them, but he started with empty PST files which dramatically changes the time it would take to index them.
Trent works in the IT department at a local school, and they are currently running a Microsoft Exchange Server. They're thinking of moving over to Google Apps. What does Leo think?
