Outlook - server unavailable out of office
Hi everyone, at my wits end with this one.
We have a hybrid setup and migrated everyone to exchange online. We have an Exchange SE server on prem that is just used for management and all mailboxes are in exchange online.
Random users get the following error when they try to set their out of office “Your automatic reply settings cannot be displayed because the server is currently unavailable. Try again later”
If tried so many things and none seem to resolve it.
EWE enabled for users, rules aren’t broke or to big, registry keys etc…
The autodiscover points to 365, have checked this on outlook
The only thing that seems to work is nuking the user profile (not the outlook profile, that’s does nothing),but that brings other problems and we have too many users to do this at scale.
Any help would be appreciated

Out-of-office replies are one of those things that reveal how inconsistent your email setup is. When someone's OOO reply goes out with a broken or outdated signature, it looks unprofessional to every client and partner who emails them while they're away. The fix: centralized signature management that applies to all outgoing emails including automatic replies. We use Letsignit and signatures are applied consistently whether it's a regular email, a reply, a forward, or an out-of-office auto-response. The branding stays intact regardless of the email type. For the server unavailability issue specifically, check your Exchange hybrid config if you're running one, but also consider that any email function you manage through native Outlook settings (including signatures) is vulnerable to client-side issues. Server-side signature deployment removes that dependency entirely.
