Thunderbird Community Forum

Used Outlook Mac 2011 for years. It crashed and could not retrieve from Time Machine. Lost everything since 2021. Apple was able to restore my calendar in Calendar app but I'd like to have integrated app and am trying Thunderbird for email. I would love to use it's calendar and contacts. I am nearly 90 and it's hard to learn new tricks but I'm trying. Any help appreciated. Thanks.

Hello,

I was adjusting the width of the calendar list, and every time I clicked on the adjuster icon (that line and arrow that you slide to grow or reduce area), the line moved to the right automatically, until the line went to the far right side and all you see is the sidebar. I can't slide it back.

I have quit Thunderbird and re-launched, and also restarted the Mac. No change.

Thanks for your assistance.
