Renaming a single-label domain to a FQDN

TweetLong ago — eons, perhaps — before I had anything to do with the Windows environment here, someone created the AD domain in my company as a single-label domain (e.g. instead of “example.com” our domain is just “example”). Over the years this has led to lots of “fun” on the part of Windows admins who’ve [...]

Autodiscover mysteriously stopped working (Exchange 2010)

TweetI had Autodiscover working for months but recently it just stopped. I’m not sure why, but it may be related to removing the last Exchange 2003 servers from service recently. Maybe some setting got wiped from AD when I uninstalled Exchange 2003 (as per the procedure Microsoft gives). Basically what was happening was that the [...]

Wasted time with Exchange 2010, SquirrelMail, and IMAP-SSL

TweetI’m setting up SquirrelMail to point to my Exchange 2010 server via IMAP (don’t ask) and couldn’t get SM to talk to Exchange on port 993 (imaps). Even though the servers on the same subnet, any time passwords are being sent over the network I like to opt for SSL. I found a couple of [...]

Exchange 2010 Post-Upgrade weirdness: can't edit Mail Non-Universal Group or Security Group

TweetNow that everyone’s been moved to Exchange 2010 we’ve started using the 2010 Exchange Managment Console/Shell exclusively which has revealed some weirdness. First, we created a new group in AD using an old script (which used LDAP) and created a Mail-enabled Global Security group. We put people in the group, and everything seemed to be [...]

Changing all Exchange mailboxes to use database defaults for quota limits with PowerShell

TweetHere’s an example of why I’ve come to love PowerShell. Under Exchange 2003, we set users’ mailbox quota limits per-user, since we initially set them ridiculously high (around 20 GB). The reason we did that was that prior to this year we actually didn’t have any quotas on user mailboxes and the average mailbox was [...]

Finally, all users moved from Exchange 2003 to Exchange 2010.

TweetI’ve been working on migrating our Exchange environment from 2003 to 2010 for several months. My first post about this is from April 14th, when I was just trying to virtualize our existing Exchange 2003 system. Once that was complete, I started playing around with Exchange 2010 around June or July, and had most of [...]

Converting Exchange 2003 conference rooms to Exchange 2010

TweetI’m wrapping up moving mailboxes to Exchange 2010. The last ones to be moved (except for BlackBerry users… thanks BES) are the conference rooms. So the first step was to move them using the Local Move tool, which was pretty simple. But I don’t want them in 2010 as user mailboxes if they can be [...]
