I'm currently seeking a new maintainer for the Lookout (fix version) add-on for Thunderbird.

It looks like I won't be supporting Thunderbird for much longer and instead will be stuck supporting Outlook again. This means my development time will be severely limited and with the recent move to drop legacy add-on support I'm afraid I won't be able to keep up.

If you are interested in development let me know either in the comments below, through the email [email protected] or ideally opening a pull request with code changes to the github repository

Unfortunately Microsoft Email servers still to this day send emails out in the proprietary TNEF format (We see this as a plain text email with a winmail.dat attachment). The Lookout (fix version) add-on decodes this attachment so you may open the attached files.

I've just published the V2.0.00 for the Thunderbird plugin Lookout (fix Version). This is an update for the coming versions of Thunderbird that significantly change how addons are implemented.

There are some known visual glitches and the debugging logs currently do not work, however attachments should de-code and save as expected. I would appreciate any testers to give it a shot.

I've just published the V1.3.00 for the Thunderbird plugin Lookout (fix Version). I have done a fair amount of work on quality of life changes to make it a bit more user friendly.

Have a look at my previous post on how I took up the maintenance of this very useful plugin if you want to know more about the history of the project.

• ATN Page Link
• Github Release Link

New in version 1.3.00

• Attachment drag and drop support
• Optionally remove winmail.dat file when finished processing. This is in options and defaults to true
• Fix attachment pane opening and closing, respects inbuilt Thunderbird preferences
• Ignore blank VCF files to minimize clutter
• Highlight event invitations - To be expanded to full lightning integration

Note: There are future plans to replace the plain text with the attached HTML file (body_part_0.html) that newer exchange servers include in the winmail.dat file.

I have just published the latest release for the Thunderbird plugin Lookout-fix-version.

This is a bug fix issue

Fixes are for the ics parsing

Added quick decompose_rfc822_address sanity check

Occasionally a phrase without any email addresses is used in the attendee fields and this can cause the complex regex in the decompose_rfc822_address function to freeze. As I couldn't come up with a sensible alternative (primarily due to lack of windat samples) I added a simple sanity check prior to the regex.

Added special character skip for ICS attendee data

Occasionally a special non printing character will be decoded, x20 to x7E, causing the ics file to become unreadable. Lookout now ignores these invalid fields.

Added zero( 0 ) UID check

Sometimes the UID will be decoded as 0 rather than null, if this happens lookout will now attempt one of the other UID methods as intended.

You can download this update from the Github Release page or the Thunderbird addon page
