As noted in these threads…..
There’s a workaround to use until such time as the final fix is deployed.

Hi All,
This issue might occur when you have O365/AAD enabled on the server. The product team is investigating it, in the mean time, the following workaround might help mitigate this issue:
1. On the server, go to folder %programfiles%\Windows Server\Bin\FeatureDefinitions\Microsoft PwdSync\
2. Make a copy of file Definition.xml for backup
3. Edit the original Definition.xml (if you don’t have permission, copy the file out, edit it and put it back in the folder):
Comment out the following two sections:
<!–
<HealthDefinition Name=”PasswordSyncInvalidPassword”
…
</HealthDefinition>
<HealthDefinition Name=”PasswordSyncOtherFailure” …
</HealthDefinition>
–>
4. Restart WseEmailSvc windows service.
Please let me know whether it helps nor not.
Thanks,
Works great. Been using the workaround since posted in the other threads. Even the dashboard opens fast now too.
