about MS email retrieve

[lina <lina.lastname@gmail.com>]

Hi,

My work email is Microsoft exchange one. It seems that the Microsoft
exchange can be accessed either via outlook or webpage.

I use icedove, currently has the ExQuilla plugin to retrieve email, but
seems ExQuilla going to expire.

So I wonder, how can I retrieve this email?

what is interesting is that, we share the same account (username as well
as password) in all servers, such as for the login of windows, for the
HPC, for the email, even wireless connection.
I wonder, how can they update and connect these in one big database?
Since they shared the same account, and there is a local server here to
collect Microsoft exchange email, I wonder, can I simply logged in this
server and read these as some directory or something?

Thanks ahead for your suggestions,

BR,
