cannot send or receive emails on outlook

[Patann]

For the last month I have not received and cannot send emails on Outlook, but ok on Webmail and Android phone.  Settings are correct.  What else can I try?

Hi @Patann I'm glad to hear that you are able to send email when using TalkTalk webmail, we are unable to run checks when using a 3rd party however, you can try;

Disable Add-ins

• Sometimes, third-party add-ins can interfere with Outlook's functionality. Disable any unnecessary add-ins:
  • Go to File > Options > Add-ins.
  • At the bottom, select COM Add-ins and click Go.
  • Uncheck any add-ins you don’t need and restart Outlook.
