    Hi Anastasia Zyrianova,

    Thank you for this post.

    We did increase the inotify value up to 300 but the warning is still showing up on Outlook clients.

    A customer email address is only used on one computer so very few connections.

    What do you recommend in this case?

    Thank you in advance and wish you have a good day.

    Hello Quentin Di Meo,

    Check the current per-userid limit of inotify file descriptors using the command below, and adjust the `fs.inotify.max_user_instances` value accordingly:

    # cat /proc/sys/fs/inotify/max_user_instances

    In case the issue still persists after that, check /var/log/maillog log file for details.
