Change the Exchange 2007 Server Mapi port

Posted on 2009-05-12
Last Modified: 2013-11-29
I have a situation where I'm using GFI Mail Achiver version 4 and it uses mapi to connect to the exchange server. Mapi is on port 443 which is also used by OWA. Every time I turn on mapi to allow the GFI Archiver to do it's job the server is brought to it's knee's and gets really slow. I would like to change the mapi port from 443 to something else in order to block outside attemps to access it and allow GFI archiver to do it's job.
I hope this makes sense.

Thank you for your time in reading this

MAPI doesn't use 443. It is used by OWA (with ssl), Outlook Anywhere, OMA etc.

How do you know that MAPI is on port 443? The only part of MAPI that would use port 443 is Outlook Anywhere. Where did you get that idea from?

GFI is defaulting to 443 and using mapi to archive or at least that is what it is showing on the set up screen pardon my ignorance on this issue. I will research more on Mapi ports.

Andy1970's question was responded immediately by myself and then Mestha saying that MAPI doesn't use port 443. And he posted to pardon his ignorance and said that he will learn more about ports. Then, he closes the question saying that he has figured it out.

Myself and Mestha did post well before itself giving the solution.

So, why is he closing without assigning any points. It is clear that he didn't find the answer on his own before we posted. He read both our posts, acknowledged it and then closes. I would say that it is unfair!

I did find the awnser on my own you assisted by giving me info on what port it was. The Issue was that the port 143 was allowed through the firewall to the mail-server. I closed that port and my issue was solved. I apologize for closing the question I did so in a hurry.
