Mailflow canit be changed

[gu_sta_vo_6]

Hello,

i have an issue and cannot change the mailflow settings of one of my users.

If i deactivate the mail forwarding it says that settings are updated but nothing happens.

Via powershell i get the message :

the recipient ____________ could not____________________prod.outlook.com by the domain controller can be read.This may be due to delays in replication.By existing forest mode this process should be completed successfully.

Any tips or help from anyone?Thanks!

How did you update the forwarding address for the user? Did you use an admin center or PowerShell?

Can you check the mailbox settings using Exchange Online Management Shell with the cmdlet Get-Mailbox?
