Thunderbird Community Forum

I have been using Thunderbird calendar synced to gmail a/c on Linux Mint for many years and have been able to send reminder notifications by email. Recently I had to unsubscribe my calendar and reinstall to clear a fault and the notification by email function has disappeared from Thunderbird event notifications. Can you tell me how to restore that function?

Version 140.11.1esr

Using Provider for Exchange Activesync v4.18 because my calendaring host requires EAS v16. I have recurring events (e.g., multi-day hotel reservations) which seem to SHIFT a day earlier than originally specified after a synchronization.

In event creation in Calendar the options for repeat pattern are daily, weekly, bi-weekly, monthly or yearly. There is an option to create a custom pattern, but if I enter every 28 days, because I want the event to recur every four weeks, it is over-ridden by the option above which is the repeat pattern, daily, weekly etc and the event appears daily. There appears to be no way to create an event that occurs repeatedly every four weeks (28days)?

Can anyone help please?
