Duplicate of T4665.

These warnings does not look relevant, and the syncroton log looks normal. Could you provide imap_debug log? Do you see more requests from the client in http access/error log? I didn't try WindowsMail, but it looks like it just stopped after synchronizing folders hierarchy.

The label is untranslated in German. https://www.transifex.com/kolab/kolab/libcalendaring/. So, someone will have to update localization in Transifex first.

Searching email or events is usually more expensive than e.g. filtering already loaded folders or even contacts. So, it might be not fast enough. It may require some work to make sure it's responsive.

I'm not sure. I guess, we would have to mark the input element as type=email. Need to test if that would not cause some issues.

Sure. I just described current design. These inputs are grayed out which means read-only. This comes from Bootstrap framework. Simplest fix would be to make these fields to not look like inputs, but just text.

I guess, we could change the roles filter to fix the immediate issue, but if we want to display non-managed roles we'll need possibility to list both types of roles, i.e. the filter would depend on what we want to achieve at the moment.

Confirmed. This is a known bug in fullcalendar library. Unfortunately an update is not trivial.

I'm unable to reproduce the issue. What browser did you use? The only issue I see is the fact that the list is "truncated" because of being displayed inside of the dialog not on top of it.

Fixed.

Yes. All dialogs have two buttons for closing (sometimes it's Close, sometimes Cancel). I also don't think that Share is important enough to be a separate button.

Because jsTimezoneDetect is not very active project I decided to add a workaround on PHP side. Fixed in https://github.com/roundcube/roundcubemail/commit/36485dfc345ad724f08eaa7ea30c3cc88e48a00d.

This has been fixed a few days ago. Not yet deployed at beta.kolabnow.com

Well, this is how it was designed, so you focus on finding availability not changing the time or duration. These fields are there for an informative purpose of displaying currently selected time slot. Maybe the time inputs could be editable or maybe there should be some duration input. Or maybe the slot selector above could be extendable horizontally.

Fixed. Though, there are other similar issues, e.g. with toolbar menu. We probably should not support such view resizing. I'd say it's a rare situation. I guess it's more a temporal situation, you don't want to switch to smartfon mode on desktop and work using it.

This is already fixed in git-master.

Looks like the dialog overlay does not stop event propagation.

This is a known issue. We have a ticket in Bifrost. Not trivial to fix as it's a bug in fullcalendar library.

Fixed.

Fixed.
