nye sikkerhetsoppdateringene for Exchange Server<\/a> l\u00f8ser flere s\u00e5rbarheter, der de fleste rettelsene retter seg mot etterligningsangrep (spoofing) og rettighetseskalering.<\/p>\n\n\n\nOWA Light er n\u00e5 permanent deaktivert<\/h2>\n\n\n\n
Sikkerhetsoppdateringene fra 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 deaktivere OWA Light manuelt for \u00e5 redusere potensielle sikkerhetsrisikoer.<\/p>\n\n\n\n
Kjent hybridproblem i Exchange vedvarer<\/h3>\n\n\n\n
Augustutgaven videref\u00f8rer ogs\u00e5 et kjent problem som Microsoft f\u00f8rst dokumenterte i juni 2026.<\/p>\n\n\n\n
Det p\u00e5virker Exchange Server Subscription Edition, Exchange Server 2019 og Exchange Server 2016 i visse 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 As- eller Send on Behalf-tillatelser samtidig som de aktiverer MessageCopyForSentAsEnabled eller MessageCopyForSendOnBehalfEnabled.<\/p>\n\n\n\n
I ber\u00f8rte milj\u00f8er kan meldinger sendt som eller p\u00e5 vegne av en delt postboks ogs\u00e5 dukke opp i den delte postboksens innboks. Exchange leverer den opprinnelige meldingen som et vedlegg i en separat innpakningsmelding.<\/p>\n\n\n\n
Microsoft planlegger \u00e5 rette problemet i en fremtidig Exchange Server-utgivelse.<\/p>\n\n\n\n
Oppdateringer 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 tilbyr imidlertid sikkerhetsoppdateringene for Exchange Server 2019 og Exchange Server 2016 kun privat til kunder som er registrert i Periode 2 av Utvidede sikkerhetsoppdateringer.<\/p>\n\n\n\n
Periode 2-dekning for utvidede sikkerhetsoppdateringer gir Exchange Server 2016 og 2019 sikkerhetsoppdateringer ut oktober 2026.<\/p>\n\n\n\n
Exchange-rettelsene kom samtidig med Microsofts bredere sikkerhetsutrulling i august. Oppdateringene i Patch Tuesday for august 2026 rettet omtrent 400 s\u00e5rbarheter<\/a>, inkludert dusinvis klassifisert som kritiske.<\/p>\n","protected":false},"excerpt":{"rendered":"Microsoft har gitt ut sikkerhetsoppdateringene for Exchange Server fra august 2026 for Exchange Server Subscription Edition, Exchange Server 2019 og Exchange Server 2016.
