Hi,
using your plugin, for a good number of years now it has been working successfully sending mail via Office 365 but recently (in fact this goes back to Nov last year on a low traffic site so I haven’t noticed) it now gives an error of SMTP Error: Could not authenticate.
All details are 100% correct. ‘Authenticated SMTP’ under User > Mail > Manage email apps is already checked. This is happening on multiple sites after checking. This particular one has two factor authentication set so I tried using the app password instead but same error. The other sites without two factor give the same error.
The log is:

SMTP Error: Could not authenticate.I have read all other threads which suggest doing what I’ve already tried above so am a bit of a loss.
Thanks in advance.
