Does Exchange Server store out-of-office/automatic replies in a human-readable form on the filesystem when set?

Solution 1:

How did you configure OOF/Automatic reply for your mailbox? Automatic Replies settings in Account Information in Outlook?

If so, we could run the following command to preview the OOF settings configured by Outlook:

Get-MailboxAutoReplyConfiguration -Identity "<MailboxIdentity>" | Select-Object AutoReplyState, StartTime, EndTime, ExternalMessage, InternalMessage

( If the AutoReplyState showed Enabled, the OOF settings were configured without a specific period. If it showed Scheduled, the OOF settings were configured with a specific period. )

And you could add a cmdlet behind the above command to export the external/internal OOF message to a .html file for preview:

Get-MailboxAutoReplyConfiguration -Identity "<MailboxIdentity>" | Select-Object ExternalMessage, InternalMessage | Export-Csv C:\Users\<UserName>\Desktop\OOFMessage.html
