Challenges to Import MBOX to Outlook 365

Transitioning from MBOX to Office 365 gets complicated, more so for those who have no idea how the technical aspects work. Below are some of the common barriers that most users face in the process:

• Office 365 Does Not Provide MBOX Native Support

The first ground that creates a challenge is that MBOX file formats are not supported within the Office 365 environment. Several Email clients including Mozilla Thunderbird and Apple Mail use MBOX files but with the help of advanced Office 365 functions, no MBOX file can be used. It is customary that users have to perform a transformation of MBOX files into a file format, which is accepted for import into the given platform thus creating an additional hurdle on the way.

• Risks of Loss of Data

Also, while importing or exporting any data, especially folders filled with a lot of emails and attachments, there is the possibility of data loss during migration, and this is especially on the manual methods of data migration. This is because in manual methods even the slightest mistakes can lead to improper data transfers. Data corruption is of utmost importance especially for the companies that rely on their emails and email boxes for recordkeeping and archival, especially for legal purposes.

• Manual Migration Requires a Lot of Time

If you are importing MBOX to Microsoft Office 365 on your own, it could be long and annoying. Converting email files and later importing them does take a few hours or even days, more so if you have different mbox files. Additionally, it is challenging in the absence of the appropriate technical know-how.

• Dealing with MBOX Files of Large Size

MBOX formats are prone to accumulation of bulk data especially if they are used to store old emails over the years. Uploading such heavyweight files on Office 365 without proper tools will result in migration failure, speed issues, or file damage and all these will make it worse.
