Users getting ‘flooded’ with not read notifications (NRNs) for old emails and meeting requests

I’m being placed under quite a lot of pressure from senior management over a relatively trivial issue. Basically the vast majority of users are complaining that they receive not read notifications (NRNs) for old emails and meeting requests in large numbers multiple times a day. I know something strange…

"Delivered-To" Header in Exchange

In some SMTP server implementations (i.e. Postfix) you can enable Delivered-To and X-Original-To headers that will be added to your email. (or [X-]Envelope-To)

This is very helpful with distribution lists to determine which e-mail address the mail has been redirected to.

So, when the mail has been sent to [email protected], you can see in the Delivered-Toor

Email hoarder intervention and education – (Exchange environment)

Throughout my career, I’ve encountered quite a few users who were email hoarders…

I’m managing a 100-user environment where users previously had 100mb quotas and a basic Cyrus IMAP/Postfix solution. That led to lots of locally-stored mail and the related problems with data-retention and lost mail following PC failures.

I promptly…

Schedule/queue large e-mails in Exchange 2010, defer until latency drops My challenge

We have Exchange servers at various sites, but also aboard ships. The ships are connected to our network through satellite links when at sea, but switch to WiFi bridges when in port.

Due the high latency (500+ ms) and not-uncommon drop-outs (e.g. when the ships are turning), attempting to send any e-mails above…

Get individual message size for all Exchange 2010 users

I need to make a report with a list of the largest messages on an Exchange 2010 server. I looked through the commands that I could use, and Get-MailboxStatistics isn’t granular enough – I need to find individual messages >25MB and print their size, user account, and subject. This is for a migration to Google Apps, so I can figure out who (if…

Outlook 2011 client, Exchange 2010 server; letters missing in text of sent items

On a Mac client running Outlook 2011 connected to an Exchange 2010 server: all of a sudden, characters are getting dropped in outbound e-mail messages. The client machine has been rebooted and this is still recurring with every message sent.

Does anyone have any idea what would cause this? Feels like a throwback to…

Two emails receiving the same Message ID

A user is experiencing a problem whereby when sending emails, some emails are being allocated the same Message ID. The issue looks to occur when the user has a draft email and they forward the draft to one person, and then later send the draft to another person.

I have done an email trace in Exchange, searching only on Message ID and Exchange is returning…
