If you find that some Outlook clients stopped connecting to the Exchange Online mailbox but OWA and ActiveSync is still connecting then check if modern authentication has been disabled for your O365 tenant To check run: Get-OrganizationConfig | Format-Table Name,OAuth* -AutoIf you find it is set to False and all your Outlook clients are 2013 or newer then enable it by running:Set-OrganizationConfig -OAuth2ClientProfileEnabled $trueYour disconnected users should start connecting within a few minutes.
I have a NAS running Open Media Vault (OMV) and this week it decided to not display the web front end. When browsing to http://omvIPaddress I received the below error: OMV\Exception: Failed to read file ‘/var/cache/openmediavault/cache.omv\controlpanel\login_js.json’ (size=0). in /usr/share/php/openmediavault/json/file.inc:207 To resolve the issue I connected to the NAS using secure shell: ssh root@ipaddressOfYourNAS and supplied the root passwordAfter authenticating and connecting I ran omv-aptclean and rebooted the server for good measure. I was able to access the web front end again after running omv-aptclean as per above.
