Bt internet email with Mac Outlook and calendar

Hi all,

Having some issues with my btinterent account. Set it up on outlook on the mac, and all was fine. then started getting an issue sending emails with a 3253 error/connection to server dropping. Tried a number of the suggesstions with the terminal/clearing the cache, recreating under another profile. All to no avail. Any ideas?

Also, I'd like my btinternet account calendar to appear on my iphone/mac. Help!

Cheers

Nick
