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.
