Bounce Processing and Process Inbound Emails Failure, Error message: Could not connect to MailStore

Question

We have recently been getting scheduled job failure notices for both Bounce Processing and Process Inbound Emails. This happened out of the blue a week or two ago... it's been fine for a good couple of years. Nothing has changed with the email associated with these jobs. I have changed the password to the email address in case there was an issue there, but it's still not working. I have been in Microsoft settings as well and can't see anything that would have changed. Can anyone help?

We are running CiviCRM version 5.52.2 with Joomla 3.10.11

I experienced the same thing!

It seems like Microsoft is depreceating Basic Authentication (at the end of October 2022)

Here is a walkthrough I received on email from our phone company, fixing this:

5 steps to show how to opt-out of disabling Basic Auth for EWS in Microsoft 365 Admin Center interface.

1. Log in to Microsoft 365 Admin Center and click the green Help and support button in the lower right hand corner of the screen.

2. Search for “Diag: Enable Basic Auth in EXO” in the search field

3. Click “Run Tests”

4. Choose “IMAP” in the “Protocol to Opt Out” drop down and select “Update”.

5. Microsoft will run Diagnose for a short while and display the below view if successful.
