Setting an out of office message/auto response for all email accounts/mailboxes

[wijcc]

Hi,

Is there an easy way to set up an auto response/out of office message for all email accounts and shared mailboxes that we have in our organisation, we have an exchange online/hybrid set-up? I need to set-up an out of office message for all the mailboxes both user accounts and shared mailboxes we have for a set period?

Thanks in advance

I mean, I googled it, knowing it was possible...

Seen that already thanks but I am not an expert/proficient in powershell scripting, I need to do it for about 500 mailboxes (user & shared mailboxes), so need to do some scripting to apply it to all the mailboxes

Ok, I can help with that. Do you want the message to be rejected with a reply, or allow the message, and then reply (traditional OOO response). The latter is once, per mail sender, so if John A sends to John B once, John A will get John B's OOO. But if John A sends again, he won't get an OOO.

If you want to reject and reply, John A will always get an "OOO" (it's not technically an OOO, but you get the drift)

I managed to get this sorted using a powershell script to set an OoO message for all accounts
