The working of the Mac OS and its data is not the same as others. If you’ve worked with OLM files, you know they tend not to be a “universal format” in the world of email. So, when someone decides to import OLM to Zoho Mail, the obstacle is not just migration. This guide will discuss how the Outlook for Mac to Zoho Mail transfer takes place for free or with an OLM Converter. Whether you have a few users or an organizational history of Teams, all is transferred in one go with ease!
User Query:
“Our team wants to open OLM file in Zoho Mail, and we have multiple users with large OLM files. What’s the best approach for an efficient transfer? Is there a bulk migration option, or do we need to process each Outlook for Mac file individually?”
A lot of Mac-based teams gain comfort with Outlook, but later realize that they really need something cloud-native and more integrated across apps. That’s where Zoho Mail comes in.
So, even though it is very advantageous, there are some difficulties with this import. Let’s first go through them to have a simplified data transfer later.
An OLM file is a data format used by Outlook for Mac. It stores emails, attachments, contacts, and calendars, all in a format unsupported by Zoho or any non-Microsoft program. Thus, you cannot directly import .olm files into Zoho Mail. To transfer OLM files to Zoho Mail, you have to either convert or extract the mailbox to a supported format (like MBOX or PST). Later, upload it to the cloud.
This sounds complicated, but we will break it down step by step. First, let’s ensure you have everything that you will need:
Pro Tip: For multiple users, create a migration batch that includes mailbox size, user priority, and any expected downtimes to minimize user conflicts or confusion afterwards.
As Zoho Mail supports IMAP sync, you can conveniently perform the transfer with a dual-client bridge. The steps to follow are quite straightforward:
This method is ideal for small-scale transfers, but not the enterprise migrations. Also, it doesn’t retain your folder structures or integrity and can result in missing imports. So, it is best to move to a more scalable, versatile, and reliable solution.
For those migrating multiple OLM files or managing enterprise accounts, the SysInfo OLM Converter provides a more manageable solution. It directly imports OLM files into Zoho, with no worry of losing data or creating organizational issues manually. Plus, it maintains hierarchy, timestamps/metadata, and uploads OLM files in bulk for multi-user account migration.
Moreover, the data is completely kept secure with full accuracy, and you can even try the Demo Version first to know about its functionalities. Even with it, free export upto 50 emails per folder into Zoho.
