O365 Add Fail - TaskException: There are multiple recipients matching identity2022-04-15 09:18:26
As the name suggest, this error will occur if an O365 ADD conflicts with an existing O365 contact. While this may in fact indicate a valid issue, if it’s a synced object, it may be due to a known bug in pre-v4.1 installations.
Example of error:
Add Error | TaskException: There are multiple recipients matching identity "DianeMiller@domain.com". Please specify a unique value. Add Fail | DianeMiller@domain.com
If you are running any version prior to v4.1 AND there IS an existing Destination contact (previously synced by UnitySync), this error may be caused by a known issue.
This has been fixed in v4.1. It is recommended you upgrade to v4.1 to resolve this issue and contact firstname.lastname@example.org for further assistance.
