Hi community
I am trying to install the Microsoft Office 365 Connector
but it fails
the /var/log/univention/join.log shows

It looks like it was a problem with the notifier

Univention Directory Notifier ID and the locally stored version differ.
This might indicate an error or still processing transactions.

I followed all the descriptions regarding listener / notifier problems and now instead of
xxx…connection refused i get increasing counters for transactions …

watch -n 15  'univention-directory-listener-ctrl status | egrep -3 Last'

[Lucky]

after resync

 univention-directory-listener-ctrl status | egrep -3 Listener
Listener status:
 run: univention-directory-listener: (pid 7143) 927s, normally down

Current Notifier ID on "dcsc.office.company.com"
 1613823

Last Notifier ID processed by local Listener:
 1613823

everything is working fine and the

40univention-office365

was going thru without any issues
