Code: -3259 server unable to connect

For a while I'm trying to use my outlook again.

A couple of months ago I bought a new macbook and I haven't used outlook for a while.

Now I want to start using outlook again, but every time I try, whatever I do I get the following message:

"There has been a time out on the server. The server is not available or might be overloaded"

Code: -3259

Mail can't be synced.

Accountname "......."

I've already tried to make new identity, new account, remove and install outlook, but nothing seems to work.

Anybody knows how to solve this issue?
