Importing ics files doesn´t work

kslt90

Hello,

i try to import an downloaded .ics file from an shared calendar link and import it to my grommunio calendar with the built in gromox import commands, but it doesn´t work.

If i use sudo gromox-eml2mt feiertage.ics | sudo gromox-mt2exm -u user@domain.tld -B Calendar/Feiertage to import the file "feiertage.ics" into the calendar subfolder "Feiertage" the command doesn´t recognize the file as an .ics file and just one entry is created as a empty message.

If i use gromox-eml2mt with the --ical flag
sudo gromox-eml2mt --ical feiertage.ics | sudo gromox-mt2exm -u user@domain.tld -B Calendar/Feiertage
or gromox-ical2mt command
sudo gromox-ical2mt feiertage.ics | sudo gromox-mt2exm -u user@domain.tld -B Calendar/Feiertage
then the -B option to specify the target folder is ignored and all appointments from feiertage.ics are imported into the main Calendar folder instead of the subfolder Calendar/Feiertage

Thanks for your help!

kslt90 then the -B option to specify the target folder is ignored and all appointments from feiertage.ics are imported into the main Calendar folder instead of the subfolder Calendar/Feiertage

could you share the actual command you have used? Haven't tried it yet but such things are helpful.

And btw, gromox-eml2mt is the actual program. the -ical and so on are just wrapper so you don't have to use the command switch for it ^_^.

First i used

sudo gromox-eml2mt feiertage.ics | sudo gromox-mt2exm -u user@domain.tld -B Calendar/Feiertage

which leads to a single empty entry in the calendar subfolder "Feiertage" which is not a calendar appointment. It seems to be a message, which makes sense because gromox-eml2mt is used to import messages.
The second command i tried was

sudo gromox-eml2mt --ical feiertage.ics | sudo gromox-mt2exm -u user@domain.tld -B Calendar/Feiertage

This is the same command as above but with --ical flag to specifiy that it is not a message but a calendar file. With this command it imports all appointments in the Calendar folder and not in the subfolder Feiertage (Calendar/Feiertage)

and the third command i tried was

sudo gromox-ical2mt feiertage.ics | sudo gromox-mt2exm -u user@domain.tld -B Calendar/Feiertage

which gave me the same result as the second command. It imported the appointments but again into the root calendar folder and not in the specified subfolder.
As i understand the -B option should specify the path to the target folder but it is somehow ignored because in any case it´s always the root calendar folder where the appointments are imported.

Ok, i also only get it in IPM_SUBTREE/CALENDAR but not in IPM_SUBTREE/Ferien or IPM_SUBTREE/CALENDAR/FERIEN2

The Gromox Documentation says:

Examples

Import of an RFC5322 message (sometimes with .eml file extension) to drafts:

gromox-eml2mt msg.eml | gromox-mt2exm -u recipient@domain.example -B drafts

Import of calendar objects:

gromox-ical2mt meeting.ics | gromox-mt2exm -u recipient@domain.example

So as i understand at the moment it is not possible to specify target folders for ics import. It seems to be always the root calendar folder. Only the import of messages will accept the -B option to specify the path.

It's a pity that it doesn't work, beacuse gromox-eml2mt is nice and powerful built-in tool and i´m sure that i´m not the only one who uses more than one (sub)calendars.

Schad.. er hat zwar nicht gemeckert aber es auch nicht "lesbar" abgelegt...

At the moment i use a Outlook Addon called "Caldav Synchronizer" at work to synchronize my Office 365 business calendar with my private calendar in grommunio. Therefore i created a new calendar called "Work" as subfolder under the Calendar folder. But this solution is not optimal as it depends on a third party outlook addon. In addition i have to store my grommunio credentials on my computer at work.
Instead of this I would rather publish my Office 365 calendar and download it with wget as ics file using a cronjob on my grommunio machine. this cronjob should also import the downloaded ics file into the created "Work" calendar let´s say every hour with the gromox-eml2mt commands.
This would be a safe, easy and fast way to subscribe external ical calendars with out any third party tools, addons, software etc.
