From 59c2a0db703889c168926ef23140c51715a02552 Mon Sep 17 00:00:00 2001 From: alexcotsalas <116087923+alexcotsalas@users.noreply.github.com> Date: Wed, 6 Aug 2025 07:12:13 -0700 Subject: [PATCH 1/2] Update Add-AvailabilityAddressSpace to clarify configurations needed for Free/busy sharing between online tenants Removes -AccessMethod OrgWideFBBasic which was deprecated some time ago when basic auth was deprecated in Exchange Online. Clarifies that -AccessMethod OrgWideFB is deprecated for accessing target forests in Exchange Online. Adds -AccessMethod OrgWideFBToken which is now the only way to establish AvailabilityAddressSpace for Freebusy sharing across two tenants in Exchange Online. Clarifies that -AccessMethod OrgWideFBToken also requires TargetTenantId and TargetServiceEpr for a successful configuration. --- .../ExchangePowerShell/Add-AvailabilityAddressSpace.md | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/exchange/exchange-ps/ExchangePowerShell/Add-AvailabilityAddressSpace.md b/exchange/exchange-ps/ExchangePowerShell/Add-AvailabilityAddressSpace.md index b07f62ef9e..0e4585433d 100644 --- a/exchange/exchange-ps/ExchangePowerShell/Add-AvailabilityAddressSpace.md +++ b/exchange/exchange-ps/ExchangePowerShell/Add-AvailabilityAddressSpace.md @@ -81,8 +81,8 @@ In Exchange Online, this example sets up the sharing of free/busy information wi The AccessMethod parameter specifies how the free/busy data is accessed.
