How to Convert Thunderbird (MBOX) Emails to MSG Format?

[Client Thomaswilson081]

I am currently facing a situation where I need to convert my Thunderbird emails (stored in MBOX format) into MSG format. The reason is that my organization is migrating from Mozilla Thunderbird to Microsoft Outlook, and Outlook supports MSG files much better for individual email management and sharing. I have multiple MBOX files with important emails, including attachments, formatting, and metadata (To, From, Date, Subject). Manually saving each email is not practical because the mailbox is very large. Could someone please suggest a safe, reliable, and efficient way to convert Thunderbird MBOX emails to MSG format without data loss?
