I use Outlook on my PC to download emails from Outlook.com. The software is just recently constantly asking for a password which I know is correct as I have used it to log onto Outlook via a webpage.
I phoned BT business helpdesk. The person said it was a known problem as Outlook has amended their security. It would cost me £149 to correct and I have just read a text to me that a BT Pro Setup consultation has been setup for 31 March 2023. This is 3 months way. It is currently 20 December 2022. It must surely be possible for BT to solve this issue sooner than 3 months. Please help
Check if Outlook is running in compatibility mode
Find the Outlook.exe file on your computer. ...
Right-click the Outlook.exe file, choose Properties, and then choose the Compatibility tab.
If any of the boxes on the Compatibility tab are checked, uncheck them, then choose Apply > OK.
I have a similar problem since 5 Jan with e-mails and Outlook, using a BT-supplied Domain, with BTConnect mails routed to the domain address. Outlook on all PCs (Windows 10) is via a subscription service Office 365 (direct with Microsoft) and is up-to-date. Outlook repeatedly asks for username and password. Access via Webmail works. Thought it's an authentication problem (the removal of basic authentication) so, despite being on Outlook 2016+, forced Modern Authentication via a registry change but this made no difference.
We have received NO notification of any change and certainly not any additional charges such as £149 or £3 a month (indicated elsewhere), so presumably this is merely a fault and not a change of policy ...
Not sure I fully understand Rachel's instructions above, there is no Compatibility tab in my Otlook.exe Properties.
What do I need to do to get this problem fixed? A simple set of instructions please if I need to change in our Outlook set-up.
Update on my post above. We were notified (twice) in Oct 2022 about the demise of such access via POP on Email Lite with a domain name but ignored them, confident we were not using that method. Seems we were, so looks like my problem after all.
