I am doing a cutover migration, and had abut 5 users out of 100 get an error as follows:
"The operation couldn't be performed because <email address> matches multiple entries"
I have not been able to find much on this error.
Any help appreciated.
I believe I resolved this by simply removing some account from the organization tab in AD, regarding manager, and reports. I belive the users were no longer in AD, but still listed as a manger.
Should now be resolved.
Have you ever manually created these 5 users in MOP? If so, please remove the previous users which use the same user name with the 5 users, and run the migration again.
Meanwhile, you should have received an error report about the migration. Is there any more information in the report?
Is there any updates about the issue?
I am glad to hear that the issue has been resolved. Thanks for sharing your solution here. Appreciate your time and efforts.
