TbSync

Rated 3 out of 5 stars

An essential addon if you're using Thunderbird with Exchange accounts.

I would have given it 5 stars if it wasn't for one major issue. If you are syncing to an Exchange account that has many Tasks (I have about 1600) then Thunderbird becomes almost unusable. Switching from say the tasks tab to the email tab will cause Thunderbird to become unresponsive for up to 60 seconds. The same happens if I try to switch from calendar tab to email tab.

I don't think that it's a Thunderbird problem because if I copy all the Exchange Tasks to a local calendar and then switch off Exchange Tasks sync in Tbsync then the problem goes away and Thunderbird is perfectly usable again.

I'm running Ubuntu 20.04.4 LTS with Tbsync version 3.0.2 and Thunderbird version 91.9.1.

I did try emailing the developer for his thoughts on the issue, but I never received a reply. I wonder if anyone else has experienced this issue?
