Hi My problem: My hotmail account will no longer send emails. The error message I get is 

 From Microsoft: "We can't sign you in Your browser is currently set to block cookies. You need to allow cookies to use this service."    (NB my Firefox browser cookies is set to 'standard' and the settings had not been changed.  Plus I've tried playing with the settings, makes no difference)
  From Thunderbird: "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again."

When? Started on 6 or 7 Oct, At this point, both receive and send failed. Last message was just before a Thunderbird update. We were in France, using hotel internet, which Microsoft hates. (so I didn't try to fix it until we got home).

Other info: However my hotmail address still worked well on my laptop's Outlook; internet login, Thunderbird on another laptop (Win 11, and more recent installation of Tb) and on my phone (Android, FairEmail), ie has not been blocked. My usual laptop is Win 10. All other emails within my Thunderbird are working fine. The outgoing SMTP for hotmail is: smtp://smtp.office365.com (smtp://smtp.office365.com) See image attached.

What since: A forced update of Windows (as rec'd by local techy) restored the receive function and speed, which had become sluggish. Hotmail still can't send. I've logged in and out of my microsoft account online, and have changed my MS password (and therefore that of my hotmail account), plus restarted everything lots of times. No difference. I have not got office365 except what came free with windows. I avoid office/MS apps where possible.

PLUS: Discovered that my Tb profile is humungous, 45gb, of which a fair chunk is this last couple of weeks. Most of it is not visible emails. Any advice ? - can I start a new profile and ditch the old? 

                   Help please......................

Thanks Eunice Lord

You have to accept cookies in TB Settings/Privacy & Security, for OAuth2 authentication to work. OAuth2 should be the authentication on the incoming and outgoing (like here).

Remove the entries for the account from Saved Passwords in Settings, restart TB, enter the account password in the OAuth window, which will store an oauth:// token in saved passwords, used for both incoming and outgoing.

You can create a new profile from Help/Troubleshooting Info, about:profiles, without affecting the old profile. Data like local mail and address books can be transferred from the old to the new, and once the old profile is no longer needed, it can be removed in about:profiles.
