Unfortunately, we’ve confirmed that Outlook for Mac version 16.45 once again has a bug in the OLM import feature. The bug is that Outlook will appear import the OLM files but no messages will actually be imported. This is fixed in Outlook 16.46. If you are having trouble importing OLM files into Outlook, you have two solutions:
- Convert to PST format instead and have Outlook import the PST file
- OR, update Outlook to version 16.46 or later. As of the time of this article, version 16.46 is only available in the Beta channel in the Microsoft AutoUpdate tool. You can select the Beta channel in the Advanced settings of the Microsoft AutoUpdate tool.
Thanks to Chris J. for helping to confirm this bug.
