I ran into a user today who kept receiving a prompt in Outlook that her quota had been surpassed. The Helpdesk looked at it and found that she had a huge amount of data in the Calendar folder within her mailbox.
It turns out she had a couple pesky recurring meetings which had attachments. And it turned out she’d inadvertently duplicated said meetings.
So the combination of several years of weekly recurrence, two attachments, and duplicates caused the innocent meeting which was only a megabyte or two to cause her mailbox, and everyone invited to the meeting, to balloon to several gigabytes in size.

When writing a new email in Outlook and you also use Microsoft Communicator, Outlook can display the current status in real time of the people you are writing to.
If Outlook is not displaying the status like it should, check the following option:
Outlook 2007:

File Options Contacts Check the box next to “Display online status next to name” If you enjoyed this guide – follow me on Twitter @dreys!

This occurred today when attempting to run handheldcleanup.exe –u on our BES server. It occurred because when prompted for the BES server name:
Please Enter BESName: ->
An incorrect name was typed in.
To locate the name which should be input, verbatim, I looked Blackberry Server Configuration, on the Blackberry Server tab. It should provide the server name next to “Blackberry Server Name”

Rebuilding a Windows user profile is an old “cure-all” trick used to troubleshoot various logon problems, such as profile errors, unreasonably slow logon, or to restore Windows user settings to first-time-use defaults.
In Windows XP, it was possible to simply rename C:\Documents and Settings\USERNAME folder to .OLD, for example, in order to rebuild a user’s Windows profile. However, performing the same steps in Vista will create a TEMP user folder instead of a fresh profile.

Today we experienced a significant onslaught of spam/phishing email into our organization which was not caught by our spam filters. Luckily, we were able to manually create filters which stopped any additional incoming instances of this attack.
I was approached by our IT Security department to run a “seek and destroy” on the emails which were able to make it through before our blocks were in place.
First, we ran message tracking on the Exchange servers to identify the users who received the malicious email, then exported said users to a .
