1364217 - Lightning calendar refresh (sync) rate unsuitable

Status: RESOLVED DUPLICATE of bug 925245

(Calendar :: Dialogs, enhancement)

Description

[sukhoi47]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20170504105526

Steps to reproduce:

Thunderbird -> Calendar -> right click any remote calendar (like google calendar)
-> properties
-> Refresh Calendar

The refresh calendar options available are:
- Every 30 minutes
- Every 60 minutes
- Manual 


Actual results:

Sync a calendar every 60 minutes is a too high frequency for most calendars.
Thunderbird freeze/slowdown every time a sync takes place. A User with 20 remote calendars will have one syncing every 3 minutes, this means Thunderbird will freeze/slowdown every 3 minutes.
Calendars like "holidays" hardly change, there is no need to sync every 60 minutes.
And if there is a need the user can perform a manual sync.


Expected results:

More options should be available, like:
- every 2 hours
- every 3 hours
- every 6 hours
- every 12 hours
- every day
- every 2 days
- every week
- every 2 weeks
- every month
- Custom

Hope this "bug" can be fixed soon.
