Re: Outlook error when doing a search
AlexRomain I blocked my internal DNS servers from resolving outlook.office365.com. Various ways to do this, easiest is create an empty DNS authoritative zone outlook.office365.com to blackhole the dns requests. Be warned, this may break some Outlook365 webmail functions. The download attachments function couldnt work due to unable to resolve attachment.outlook.live.net, which actually just a CNAME to outlook.office365.com. But at least, your office outlook users will stop the persistent calls for support......36KViews1like4CommentsRe: Outlook error when doing a search
JanShim I found out the root cause for my environment..... Outlook 2016/2019 resolve search via Office365 instead (gasp!!), bypassing on-premise servers. This is due to auto-discover feature of recent version of Outlook 2016/2019, resolve office365 first prior to on-premise server. I had to dns block outlook autodiscover from connecting to outlook.office365.com, forcing it to use on-prem servers instead. Worked like charm.43KViews0likes12CommentsRe: Outlook error when doing a search
Had the same issue with similar environment as well, Outlook2016 was also affected. I tried everything, from reinstalling outlook, recreate profiles, remove updates, rebuilding indexes, to untick and tick Outlook from Windows Search option. Nothing worked, except disable ServerAssistedSearch. Now pushing it thru GPO, but we need the root cause as it affects the entire organization.99KViews0likes21Comments
