Hello Team,
We are hybrid (AD + Azure AD) and have many values defined in attributes msExchExtensionCustomAttribute2 and msExchExtensionCustomAttribute3 we use this for opera roles.
Basically, when we update values in it, and it is more than 90 (msExchExtensionCustomAttribute2 and msExchExtensionCustomAttribute3 combined) then it stops the sync for that user and in Sync tool we see the error
"An internal error has occurred. This operation will be retried during the next synchronization. If the issue persists for more than 24 hours, contact Technical Support.
Tracking Id: 2ca60502-d560-4f65-bfe6-f16d6ee1fa14
ExtraErrorDetails:
[{"Key":"ObjectId","Value":["24ffXXXXXXXXXXXXde611"]}]"
and in AAD portal under sync errors we see "DirectoryServiceException"
As soon as we reduce the values to 90 or less it works fine. Can you help here? I am trying to find relevant article but many i found were unanswered or related to Proxyaddresses thing. Here it is not the case of proxy addresses.

Thank you for reaching out Microsoft Q&A.
I understand you are getting an error: *
An internal error has occurred. This operation will be retried during the next synchronization. If the issue persists for more than 24 hours, contact Technical Support*when you update values in it, and it is more than 90 (msExchExtensionCustomAttribute2 and msExchExtensionCustomAttribute3 combined)Manually run a sync cycle, then from PowerShell run
Start-ADSyncSyncCycle -PolicyType Delta
observe the behaviour and let me know, if still the error continues provide the screen shot of Synchronization service and also screen shot Synchronization rules if any added for the msExchExtensionCustomAttribute2 and msExchExtensionCustomAttribute3 and also in event viewer go to windows Logs>Application observe if you got any event log error during synchronization if yes provide the screen shot of error.Regards,
Goutam Pratti. -

I have executed policytype Delta command also it is running every hour hope that would help too.
Please find requested screenshots.
Event vwr error for corresponding user.PNG
Attribute screenshot from AAD connect.PNG
PS: it is not only one user. All users are affected if the values are more than 90 values.
Hope that helps.
