A new feature with Thunderbird 2.0 is the ability to Tag messages. You can assign one of these five color-coded ‘default’ tags to a message by selecting the message(s) from the folder’s message list and right-clicking and selecting ‘Tag’ from the context menu:
- To Do
- Important
- Later
- Personal
- Work
But what if these five ‘default’ tags are not what you are looking for? At the bottom of tag sub-menu is the option ‘New Tag…’. A popup box will allow you to create your own custom tag and pick the associated color.
Once a message is ‘tagged’, the text as displayed in the message list will turn the color of the assigned tag. When you click on that message in the message list, the text turns white and is highlighted in the assigned tag’s color. At first I wasn’t too sure how I was going to use this but I am already seeing potential. I tend to send myself e-mails from work from schedule changes, to events and other items. Plus I leave other e-mails in my Inbox which I will follow-up on later. After a while I have several e-mails sitting in my Inbox which I have to go through one-by-one to see what exactly they are. With the Tags (once I start remembering what each color represents) I’ll quickly be able to see why I am still holding these messages in my Inbox. Can also be useful for organizing saved or archived messages, especially when combined with custom made tags.
Couple notes as mentioned above, you can only assign ONE tag per message. In addition, you can not CHANGE the five ‘default’ tags or their colors. If you want to change the assigned tab just repeat the process and select the new tag which you want to assign or to remove the tag select ‘0 Removal All Tags’.


[...] The one feature that many of us are anxiously awaiting would be the Tabbed Messages. In a nutshell instead of having each message(when clicked) appear in its window, they would appear in tabs (just like Firefox) instead. In regards to some of the other features,the message tagging is nice and is useful for organizing messages. Junk/Scam Mail still needs a lot of work, but seems to work a bit better (than in 1.5) in the Pre-Beta builds I have been using. Not too sure what the “custom folder pane views” are and not even sure if this feature has already been released. [...]

It seems that you can assign more than one tag in the most recent beta.

Is there a way of seeing all tagged emails across multiple accounts / folders in a single folder or even better a folder for To Do one for Important and so on?
Very much like the ‘For Follow Up’ folder in Outlook.
If there’s an Add On that would be cool – but I can’t seem to find anything.

There must be some way to change the default tags. i like the tags themselves, but the default tags are kind of annoying.
Any tricks for getting around this one?

I’m using TB 2.0.0.23 and have my AIM email account enabled in TB.
I thought the Tags were great but they aren’t. Each day I place tags on emails in my in box. The next morning, when I open up TB alllll the tags are gone. I’ve given up using them and have folders instead.
If there is a work around for this (i.e. due to IMAP AIM email causing some glitch in TB) I would be happy to give it a try.
