What is a .OLM file?
OLM is an archive of mail and data from Outlook for Mac.
- Did you know
- OLM is how Outlook on the Mac exports a mailbox for backup or transfer.
- OLM is the archive format Outlook for Mac introduced with its 2011 release to store mail, contacts, calendars and tasks locally.
- It is the Mac counterpart to Windows Outlook’s PST and cannot be opened directly by Outlook on Windows.
- What Analyser reads
- Identify and read more email, calendar and contact files: Outlook for Mac archives (.olm) and templates (.oft), S/MIME .p7m/.p7s, Mozilla Mork stores (.msf/.mab), Eudora/Outlook Express mailboxes (.mbx/.toc), phone backups (.vmg SMS, .vnt notes), XML/JSON iCalendar and vCard (.xcal/.jcal/.xcard/.jcard), LDIF (.ldi) and legacy address books (.pab/.wab/.abbu).
- Depth of analysis
- .OLM is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .OLM file
- Drag a .OLM file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
