Hello,

I have an error ExceededAllowedLength in AAD synchronization. This issue is on several users only.

Azure AD Connect has version 2.2.1.0.

Detailed information of error:

Unable to update this object in Azure Active Directory, because the attribute [extension_3e3cb7b3ae6945fbaf2c95dea6d3929a_msExchSafeSendersHash], in the local Directory exceeds the maximum allowed length. If you want to update, reduce the length in the local directory services, and then try again.

Tracking Id: 9xxxxxx7-6a68-xxxxx-b451-630xxxxx7e96

ExtraErrorDetails:

[{"Key":"ObjectId","Value":["a0xxxx4b9-74a3-43af-9de1-56axxxx1cfd"]},{"Key":"InvalidAttributeName","Value":["extension_3e3cb7b3ae6945fbaf2c95dea6d3929a_msExchSafeSendersHash"]},{"Key":"MaxLength","Value":["0"]},{"Key":"MinLength","Value":["0"]}]

Can you help me?
