It’s necessary to handle your computer stuff smoothly In today’s digital world. If you use a Mac and Outlook for emails, you might need to change your Outlook files (OLM) to another type called MSG. Why? Perhaps you want to save your emails, share them, or switch to a different email platform. No worries, though! We’re here to make this whole process easy for you. Therefore, the following will discuss two procedures to convert OLM to MSG using the reliable solution, Cigati Mac OLM Converter.

What Are OLM and MSG Files?

OLM is a file that Mac Outlook uses. In other words, it keeps things like emails, contacts, and calendars safe. But here’s the thing – you can’t open it on regular Windows Outlook. In short, Mac Outlook only supports OLM files.

On the other hand, MSG is another type of file that holds emails, tasks, and more. You make MSG files in Outlook and can effortlessly move them to your computer. Moreover, MSG files are like readable notes – they have simple text and can include attachments or links.

Frequently Asked Questions

Q: Can I convert OLM to MSG manually (without paid tools)?

Ans: echnically yes, but with major caveats. There is no direct built-in way in Outlook for Mac or Windows to convert OLM files directly into MSG. One manual workaround: import the OLM into Outlook for Mac or via IMAP, sync it to Outlook for Windows, then save individual messages as MSG files. But this is time-consuming, error-prone and not suitable for large volumes.

Q: Can I convert multiple OLM files (bulk conversion) into MSG format at once?

Ans: Yes. Many specialized conversion tools, such as Cigati OLM Converter, offer a batch or bulk conversion feature that allows you to select multiple OLM files or folders and export them as multiple MSG files in one go. Manual methods generally do not scale well for bulk conversion.
