Microsoft Outlook error -17895

Microsoft Outlook error -17895

I keep getting this message:

Error  Connection to the server failed or was dropped

Details Could not retrieve mail

            Account name: "Comcast"

Error code: -17895


I only get this will Microsoft Outlook, not Mac mail.  Started getting the error messages about 2 months ago.  It seems like this occurred before and then stopped for awhile.  I can send and receive email just fine.  Every so often, it re-downloads all the emails still on the server, unless I log into Comcast directly and delete them.


Using Microsoft Office for Mac 2011 v 14.3.9

Mac OS X v 10.9


I deleted and reinstalled the email accounts. Use incoming port 995, outgoing 465

I rebuilt main identity  with the Microsoft database utility

Re: Microsoft Outlook error -17895

having the same issue, and followed the same steps. surely we can't be the only two.


from microsoft's site:


Error -17895

Connection to the server failed or was dropped. Explanation: Could not retrieve mail.
Account name: "xxxxxxxx" Error: -17895"

This is an Entourage internal error netLostConnectionErr, and is generated when Entourage hits eofErr trying to read a network stream from the server and expects more data to be coming. It could also be generated if, when trying to create a connection, Entourage (apparently) successfully authenticates, but then the network connection closes immediately thereafter.

A network sniff could help determine whether or not the server is doing the losing of the connection (and possibly why) or whether Entourage is expecting more data than it should.

User reports: It turned out to be a mail server issue, which our ISP managed to resolve using the information provided above.

Re: Microsoft Outlook error -17895

I deleted,an reinstalled Outlook, but problem persists. Can't understand why this has started to occur after using Outlook problem free for over a year. None of my research on internet has been of help.
