Good day,

 

We’ve started migrating our mailboxes from Exchange 2007 to 2010.    We’ve started to notice that users that have been migrated to 2010 and are using POP are having issues in receiving attachments as they come in as winmail.dat, regardless of what client the sender is using.  We’ve seen this happen on multiple clients and OS’s (Thunderbird, Eudora and Mac Mail, thus far and Mac OSX and Windows).

 

Our mail system is setup where our edge servers are Sendmail’s SMTP and incoming server is Exchange.   

 

Exchange server is up to date on it’s patch level.

 

If a POP user checks OWA, the attachment is displayed correctly.  If we convert the profile to either IMAP or full Exchange (RPC over HTTP) on the same client, the attachments are displayed and come in just fine.   Creating another POP profile on the same client does not help.

 

But, if we configure a POP client, Mac Mail for instance, on a stock OSX (10.6.8) – same OS version as an effected user – where it just has anti-virus, the same mailbox profile/settings work fine, but same profile on an affected system fails.

 

 

The same mailbox that was on 2007 prior to it’s migration to 2010 had no issues with attachments via POP.

Has anyone experienced this or heard of this?   Does anyone know if Microsoft changed how the POP protocol is read/handled by Exchange 2010?   Even thought it doesn’t seem like it’s server specific related as we did get it to work on a stock OS.

 

Thnx,

-jack

Jack,

 

We had a similar issue with the winmail.dat attachments.  We configured a remote domain for Princeton.edu to never use Exchange Rich-text-formatting because there are so many different clients out there.  After we did this, people stopped getting the winmail.dat attachments.  Go under your organization configuration to hub transport and click on the remote domains to see what you have.  Then the “message format” tab has information about Exchange rich-text format.

 

Good luck!

 

Joe

 

 

Jack,

We had a similar issue – especially with iOS devices and the winmail.dat file – and for our students (our students are on Google Apps for Education, employees are on Exchange 2010 managed internally).  We adjusted our exchange settings like Joe did and it fixed the issue.  This link may be helpful:

Thank you for the feedback.

I've ran this by our exchange admins.  They had looked at this already but its not an option for us as all users who send through our exchange server, the messages will be stripped of its formatting.  Plain text only will be sent, regardless of protocol used.

Thnx,

I don’t think that is the case.  We don’t lose any formatting.

So after some investigation and Microsoft support involvement, we've identified and resolve the issue that was occurring with our POP users.  According to our email admins,

Open EMC, expand 'Server Configuration', click on 'Client Access', select your CAS server, and then click the 'POP3 and IMAP' tab. Right click on each protocol, and select 'Properties'. Click on the 'Retrieval Settings' tab and see what it's set at. Change it to 'Best Body Format'.

For those who are/were having this same issue, there's a server side solution.
