Microsoft Outlook For Mac Suddenly Has No Accounts

Posted on

This article describes how to add your Outlook.com account to an iPhone, iPad, or iPod Touch, an Android device, or a Windows phone. If you need to add your Outlook.com account to another device or app, you'll need the POP, IMAP, or SMTP settings for Outlook.com. See POP, IMAP, and SMTP settings. The most annoying issue is that Outlook 2016 for Macintosh has suddenly refused to access my me.com (iCloud) IMAP account. It repeatedly pesters me for a password. Even when I enter the correct one, it says 'cannot retrieve mail at this time.'

Outlook is crashing for multiple users at one site. It started with one user and now four are affected. It crashes at startup or shortly after with the message 'Microsoft Outlook has stopped working'.

It registers an Application Log error 1000 with mso20win32client.dll as the faulting module. I have created new profiles, run online repair, completely uninstalled with Fix It tool with no success. Creating a new profile appears to work.for a while.

It may run for several minutes or even several hours after, but will crash eventually. It does run in Outlook Safe mode, but on some of the systems no third party add-ins are installed, so I don't have much to disable. In desperation, I swapped the whole computer out for one user. Which worked.for one full day. The problem came back on the new computer! This has just started in the past couple of day and seems to be spreading.

I'm suspecting a bad Office or Windows 10 update. All affected users are on Office 2016, release 1702, with Office 365 Business Premium and Windows 10. I have a case open with Microsoft and will post final solution but am wondering if anyone else is seeing this or has ideas? Just an overdue follow-up. In my (multiple) case(s), it was definitely a specific version of the click-to-run Office 2016 that was the issue. Creating a new profile often provided a temporary fix, but it would come back.

Malwarebytes. Uninstalling and reinstalling (with the same release) also provided either no change, or a temporary fix. I was able to confirm that either rolling back to a known good release (or jumping forward, if possible by changing your release channel) fixed the problem for my users.
