Recently users have been reporting sudden issues with their Outlook, Livemail, MSN and Hotmail account in Mailbird.
These accounts simply stopped working, it can’t receive or send email anymore. Attempts to add new accounts may also fail.
It turns out, this issue is caused by Microsoft’s upgrade process. They are migrating to a new Outlook.com, which may cause issues for some users.
Microsoft has listed more details on these problems here.
The workaround that we suggest for now is to create an application specific password for your account following this link.
After that simply remove the account and add it again in Mailbird, but this time, use the new application specific password that you have generated.
If this does not work, we will have to wait for Microsoft’s to release their suggestions on fixing the error.
If you have any questions about the issue itself or how to generate the application specific password, please drop us a line in the comment section or simply send us an email.
