Exchange 2003 Meeting Requests v. Exchange 2007

I’ve been working with a client who has been reporting emails that haven’t been going through to some recipients.  He was getting frustrated because he couldn’t reliably send to personal or professional contacts.

He sent:

More failures. This was to our accountant and my fiancée. It took two days to receive this failure notice. I will forward the originals.  Have you figured out what is going on or how to fix this?

I replied:

The NDR comes back in 48 hours because the mail server attempts to connect to the other server for 2 days.

Email was never designed to be 100% timely, it was designed to deliver mail come hell or high water; so if there’s a problem with the server you’re trying to send to, our server tries and tries again, hoping the problem is fixed within 48 hours.  If it is not, our server stops trying, rejects the message and lets you know.

4.4.7 errors usually indicate some issue with the recipient’s server (from:

Numeric Code: 4.4.7

Possible Cause: The message in the queue has expired. The sending server tried to relay or deliver the message, but the action was not completed before the message expiration time occurred. This NDR may also indicate that a message header limit has been reached on a remote server or that some other protocol timeout occurred during communication with the remote server.

Troubleshooting: This code typically indicates an issue on the receiving server. Verify the validity of the recipient address, and verify that the receiving server is configured to receive messages correctly. You may have to reduce the number of recipients in the header of the message for the host that you are receiving this NDR from. If you resend the message, it is placed in the queue again. If the receiving server is on line, the message is delivered.

Problem was, I didn’t see where the recipient’s server was rejecting any emails in the logs; nor could I see why the message was getting hung up.

So, using mails to sent to his fiancee on 2/24 as a test, I found that all mails sent to her were successfully delivered EXCEPT the calendar invites / meeting requests.  So, I had to question why  that was.  Obviously, sending to that mail server wasn’t the issue; the user was not blacklisted or anything, but something was getting hung up.

The SMTP logs didn’t show anything out of the ordinary, so I figured the items were never even making it into the queue.  Using Message Tracking, we were able to verify that it never hit the queue.  It got stuck in “Message Routed and Queued For Remote Delivery”

And then two days later, the NDR was generated.

So, further investigation made me ask this question:  Are the people bouncing messages using Exchange 2007? I couldn’t tell from one of the servers (custom SMTP banner) if it was even running Exchange, but the other said “220+domain.local+Microsoft+ESMTP+MAIL+Service+Version:+2.0 0 0 71 0 47 SMTP.”

What made me ask this question was this note from Microsoft we turned up after some research:

Consider the following scenario. A Microsoft Exchange Server 2003 organization and a Microsoft Exchange Server 2007 organization exchange communications by using SMTP. An Exchange 2003 user organizes a meeting and then sends a meeting request to an Exchange 2007 user. Additionally, the Exchange 2007 user accepts the meeting request. Then, the meeting organizer uses Microsoft Office Outlook to send a meeting update message or a meeting cancellation message to the Exchange 2007 user.

In this scenario, the meeting update message or the meeting cancellation message is not delivered to the Exchange 2007 user. Instead, the meeting update message or the meeting cancellation message goes into the SMTP retry queue. If an administrator tries to open the message in the Exchange System Manager console, the administrator may receive the following error message: […]

After some time, the sender of the meeting update may receive the following NDR:

Your message did not reach some or all of the intended recipients.
Subject: test message
Sent: 8/20/2008 11:44 AM
The following recipient(s) could not be reached: on 8/20/2008 11:34 PM
Could not deliver the message in the time limit specified. Please retry or contact your administrator. < #4.4.7>

So, it looked promising — the article mentioned both calendar invites and error 4.4.7 along with the message getting stuck in the queue, but the initial scenario is not quite correct (it seems to assume the Exchange 2007 recipient got the request and accepted it; something that’s not happening here).

The Microsoft article mentioned a hotfix, which we downloaded and applied.

After the hotfix was applied, I sent a test calendar entry to the client and his fiancee (whose address which was giving us a hard time) and lo and behold, the invite went through:

(In playing with the Message Tracker, I noticed the time was being reported an hour fast.  Turns out, there’s a hotfix for that, too.)

Fonts, Fonts and System Fonts

Back when Windows 3.1 came out, it shipped with “display” fonts — these were bitmapped fonts and the precursor to True type fonts — who knew they’d still be vital in Windows Server 2003.

A client had a problem with their Great Plains installation — the fonts went all screwy and while they could still make out the display (barely) they couldn’t print checks since the Mekorma font they were using wasn’t playing nice.

Clicking on the start menu revealed the username to be in the Marlett font, a font Windows uses for drawing parts of its UI (the X in the close box, the minimize and maximize symbols, etc.). we’ve seen this problem before, and it’s usually fixed by running TweakUI and reparing the font folder. Reboot and voila.

Great Plains Font IssueSo we do that and the checks can print, but the display font is still not right in Great Plains. Everywhere else in Windows it’s fine, but Great Plains is still hinky.

We try all sorts of things — we delete all the fonts and reinstall them from the c:\windows\fonts folder of a sister Windows 2003 server; no dice.

We troll Great Plains newsgroups, we repair the font folder, we do a repair installation of Great Plains, nothing does the trick.

It has to be a font issue, but which fonts?

We have the Great Plains consultant send over his theory — a Helvetica font set. Does nothing.

Over at Experts-Exchange (a site well worth the subscription), one of the Great Plains MVPs who was helping us out posted a screen shot of her splash screen, and when compared to ours, I thought to myself “that looks like MS Sans Serif” — a system font from way back when.

Windows XP brought along a new set of fonts it used in its shell, and MS Sans Serif was deprecated in favor of Verdana, Tahoma and the “modern” UI fonts Microsoft was putting forth.

I opened up a share on a Windows 2000 box, and there was a whole bunch of .fon fonts that weren’t on our system. So I copied them over to a temp folder and tried to install them onto our server. Only 3 showed up in the list, and there were a dozen or more in the folder.

Great Plains Corrected FontAh! They were hidden. I uncheck the hidden attribute and reinstall the fonts. All of them show up in the list.

I select all, click OK, I get a few “a version of this font is already installed” errors, and then they’re done importing.

Now, MS Sans Serif is in the list of available fonts, and lo and behold, our screen is back to normal.

Many thanks to Victoria Yudin who helped us with this issue.
