Manage Microsoft 365 / Exchange Online Out-of-Office (Automatic Reply) settings without opening Outlook.
OOF Manager is a lightweight Windows desktop tool that manages your Microsoft 365 mailbox's
Out-of-Office (Automatic Reply) state for you. Sign in once, configure your weekly work hours
and reply text, and OOF Manager auto-toggles your OOF on/off at the schedule boundaries.
It also pushes the next off-hours window to Exchange as a Scheduled OOF, so the server keeps
switching auto-replies even when this app is closed.
