I use Mailbird and it happened to that. I read something about all third-party e-mail apps now need to support OAuth2 and the outlook.office365.com server address to work with Microsoft e-mail accounts.
Having said that, eM Client was still working with the old SMTP server but perhaps it would only be a matter of time before it wouldn’t. I changed it to the new requirements anyway.
Being a Microsoft product, Outlook Express would probably have been configured by them. Outlook Express is history though. The app supplied with the current OS is called just ‘Outlook (new)’. Being Microsoft, it just works.
Webmail isn’t affected. It is only those e-mail programs/apps that aren’t supplied by Microsoft.
This change only applies to those using an app such as Thunderbird, Outlook (included with the OS), eM Client, BlueMail and others. It is possible to save e-mails using one of those but typically, the apps use something called ‘imap’ where the third party program is just used to manage emails on the server rather than downloading them and saving them to the computer.
If you access emails directly in the browser without using any app, this is webmail and the Microsoft change does not apply to that. Nothing wrong with running your email account that way incidentally.
The useful part of running an app is if you have a number of e-mail addresses. For instance: I have 5 email addresses, one with Outlook, two with Virgin media, two with Google. The app can be set to get e-mails from all those at the same time and show them all in one place (the app). Its saves hopping from one e-mail address to another using webmail in the browser. Webmail is fine if not minding doing that but it is easier to set up those accounts in an app that will get the e-mails from those accounts all in one go.
The only thing that has changed is the way Microsoft expects users of third-party apps to log into email accounts held on their servers.
So me & Mrs d00d have 1 bt email addy each and 2 gmail addies each. The gmails are sent to the relevant bt address, then hers are sent to mine. She’s lazy with computers and would never bother checking her inbox.
That is the same with mailreaders too and of course the phone. I read most of my mail on my phone but the beauty of mailreaders is the addins such as managing a mailing list, different signatures etc.
I have Thunderbird on all my computers when I install it on a new computer I stop before adding email addresses then I merely copy the weirdly named folder from the contents of Appdata folder (%AppData%\Thunderbird\Profiles). On this computer it happens to be odtkoa86.default-release into the folder on the new computer with another equally weird name. This contains all the log in info etc so it was set up years ago but it saves a lot of setting up and Thunderbird is ready to go.
