Hi guys I set up Thunderbird some months ago and all good. Now I have had notification from my internet provider that my domain "Clear" is ending soon and I had to set up "Outlook" to receive emails going forward. I have done this and my internet provider has helped with a redirection from Clear to Outlook and also in my Thunderbird I have all my old Clear emails plus folders and also the new Outlook emails. Problem is when I open my emails it takes about 5 mins for them to pull through each day (most days just a dozen emails - nothing too big). Same when I send emails it sits and takes about a minute for the sending bar to drop off screen to send one email. I am using Trendmicro but that didnt cause a issue previously. I wonder if my IP has changed a setting? Any help really appreciated ;-)
