Office Connector configuration - syncing groups

Hello together,

we have a running MS365 connector and we now try to synchronise the groups.
The variable is set.
We ran the command
univention-directory-listener-ctrl resync office365-group
two times but only 13 groups out of 73 became visible.
Is it necessary to run the resync command several times?

Thanks
MarkD.
