nye sikkerhetsoppdateringene for Exchange Server<\/a> adresserer flere s\u00e5rbarheter, og de fleste rettelsene er rettet mot spoofing og rettighetsutvidelsesproblemer.<\/p>\n\n\n\nOWA Light er n\u00e5 permanent deaktivert<\/h2>\n\n\n\n
Sikkerhetsoppdateringene for august deaktiverer Outlook Web App Light permanent i Exchange Server.<\/p>\n\n\n\n
Microsoft kunngjorde utfasingen av funksjonen for flere \u00e5r siden, og minnet Exchange-administratorer i juli om at de ville begynne \u00e5 deaktivere OWA Light i august 2026.<\/p>\n\n\n\n
Organisasjoner som ikke kan installere de nyeste Exchange Server-oppdateringene, b\u00f8r manuelt deaktivere OWA Light for \u00e5 redusere potensielle sikkerhetsrisikoer.<\/p>\n\n\n\n
Kjent hybridproblem i Exchange vedvarer<\/h3>\n\n\n\n
August-utgivelsen bringer ogs\u00e5 videre et kjent problem som Microsoft f\u00f8rst dokumenterte i juni 2026.<\/p>\n\n\n\n
Problemet p\u00e5virker Exchange Server Subscription Edition, Exchange Server 2019 og Exchange Server 2016 i bestemte hybridkonfigurasjoner som involverer delte postbokser som driftes i Exchange Online og postbokser som driftes lokalt.<\/p>\n\n\n\n
Problemet kan oppst\u00e5 n\u00e5r organisasjoner bruker Send som- eller Send p\u00e5 vegne av-tillatelser samtidig som de aktiverer MessageCopyForSentAsEnabled eller MessageCopyForSendOnBehalfEnabled.<\/p>\n\n\n\n
I ber\u00f8rte milj\u00f8er kan meldinger som sendes som eller p\u00e5 vegne av en delt postboks ogs\u00e5 vises i den delte postboksens innboks. Exchange leverer den opprinnelige meldingen som et vedlegg i en egen innpakningsmelding.<\/p>\n\n\n\n
Microsoft planlegger \u00e5 l\u00f8se problemet i en fremtidig utgave av Exchange Server.<\/p>\n\n\n\n
Oppdateringene for Exchange 2016 og 2019 har begrenset tilgjengelighet<\/h3>\n\n\n\n
Oppdateringen for Exchange Server Subscription Edition er tilgjengelig for alle kunder.<\/p>\n\n\n\n
Microsoft leverer imidlertid sikkerhetsoppdateringene for Exchange Server 2019 og Exchange Server 2016 kun privat til kunder som er registrert i periode 2 for utvidede sikkerhetsoppdateringer (ESU).<\/p>\n\n\n\n
Periode 2 ESU-dekning gir sikkerhetsoppdateringer for Exchange Server 2016 og 2019 ut oktober 2026.<\/p>\n\n\n\n
Exchange-rettelsene kom samtidig med Microsofts bredere sikkerhetsutrulling for august. Oppdateringene for Patch Tuesday i august 2026 rettet omtrent 400 s\u00e5rbarheter<\/a>, inkludert dusinvis som var klassifisert som kritiske.<\/p>\n","protected":false},"excerpt":{"rendered":"Microsoft har lansert sikkerhetsoppdateringene for Exchange Server for august 2026, for Exchange Server Subscription Edition, Exchange Server 2019 og Exchange Server 2016.
