Azure AD Connect version 1.1.751.0 released for download only

Wednesday, April 18, 2018
Microsoft just published Azure Active Directory Connect version 1.1.751.0. This is a big fix version that resolves two specific issues:

  • Corrected an issue where automatic Azure instance discovery for China (21Vianet) tenants was occasionally failing.
  • For AD FS there was a problem in the configuration retry logic that would result in an ArgumentException stating "an item with the same key has already been added." This would cause all retry operations to fail.
Since these issues only affect a small number of users this build will not be deployed via Auto Upgrade. Affected users will need to download this version directly from the AAD Connect download site.
