Are you deleting Office 365 accounts? If you do (e.g because they stop working as they reguarly do) then the calendars for that account don’t get deleted. If you then setup the account again, you get another new set of calendars and so on.

This thread here How Do You Delete Calendars and Address Books? explains how you can delete the calendar database manually. Note that this deletes ALL your calendars, so you must be able to resynchronize or restore from backup to get the ones you actually want back.

None of the above, actually. Create account once, and use it. The screenshot with 7 copies is the result of two years of usage.

The one with 2 copies is from one (!) week of usage.
Interesting thing: one of the Windpark calendars contains a recurring item, the other contains at least one new Teams meeting. Which I found out after wandering: I did create that meeting on my pc, or did I forget?

… Aaaaand… Number 3 arrived!

I just checked, and number 4 has appeared. This multiplying is happening even faster than on my X10ii!

I have the same issue : 8 copies of the same calendar account but only one seems synchronized. It’s unusable.
Need for an urgent fix !

Same here, on Xperia X (Duplicate xchange calendars, hundreds of entries over the years).

It’s not a new thing. I used to copy the sqlite calendar file and edit it by hand to get rid of extra entries. I don’t bother anymore (calendar are duplicated, but entries are not).

I pull/push from a Zimbra server. Switching to Caldav does not allow me to remotely create new entries on this server.

Note: I’ve not reflashed the phone yet, just kept upgrading SailfishOs. It may be an old error now fixed but keeping alive by broken configuration. I’ll post here if re-install helps.

Can anyone use Xchange without calendar duplication ?

Could it be that every time you create a new appointment in SailfishOS, that a new calendar is created?

Edit: no, a quick test does not show a new calendar.
