Microsoft is disabling SMTP/IMAP authentication on October 22 - Reconnect your Office 365 accounts using OAuth

TL;DR



Microsoft is deprecating "Basic authentication" (SMTP/IMAP) on October 2022. You can read the official article here
In practical terms, it means that all Outlook / Office 365 accounts connected to MailReach using SMTP/IMAP authentication will be disconnected from MailReach on October 2022.
To avoid having your Outlook mailboxes disconnected, you need to reconnect them using Microsoft OAuth Protocol (don't worry, it's pretty easy, see below).


For Office 365 / Outlook accounts - follow this process to reconnect using Microsoft OAuth



In MailReach > Email Warmer > Find the email account and click on Show.
Go in Settings > Edit credentials
Under Outlook/Office365 click on Sign in with Outlook/Office365
Then select the same mailbox (you need to be logged in to this mailbox to be able to Sign in with it).
That's it, you successfully reconnected this mailbox using Microsoft OAuth.
If you have other mailboxes in this case, repeat the same process.

For Custom SMTP / SendGrid / Mailgun / Sendinblue with an Outlook / Office 365 mailbox connected as IMAP, follow this process



In MailReach > Email Warmer > Find the email account and click on Show.
Go in Settings > Edit credentials
You'd need to enter your SMTP username / password
Click on Edit and if your SMTP credentials are correct, you'll be guided to Sign in with Outlook/Office365 for IMAP.
Then select the same mailbox (you need to be logged in to this mailbox to be able to Sign in with it).
That's it, you successfully reconnected this mailbox using Microsoft OAuth.
