This blog explores a common error related to corrupt OLM files, explains the role of OLM files in Mac Outlook (similar to PST files in Windows), and offers practical solutions to overcome such issues. Understanding the OLM format is crucial before attempting any recovery or repair methods.
How Do OLM Files Get Corrupted?
OLM file corruption can occur due to several reasons, often leading to errors and restricted access in Outlook for Mac. One of the most common causes is a virus or malware attack on the system. In some cases, running an outdated version of Outlook can also trigger corruption issues.
Other contributing factors include Exchange Server crashes, sudden removal of storage media, or hardware failures where the OLM files are saved. These issues can result in damaged files and loss of access to essential Outlook data.
A real-world example from a popular Mac forum highlights the impact:
“While working on my Mac, I can’t send or receive any emails in Outlook and I’m seeing error code 17099 in Outlook 2011. I urgently need to send an official email, but this error has completely disrupted my work. Can someone please help me resolve this?”
This type of scenario emphasizes the importance of understanding the causes and applying the right solutions promptly.
Main Reasons Behind Outlook for Mac Error Code 17099
Error 17099 in Outlook for Mac often relates to issues with sending emails. Below are some of the most frequent causes:
- SMTP Server Blocking: The outgoing mail server might restrict email delivery if it detects unusual or unauthorized behavior.
- Improper SMTP Settings: Incorrect configuration of the outgoing server can disrupt the email-sending process.
- Damaged Email Content: Emails with corrupted attachments or improperly formatted headers may trigger this error during transmission.
- IP Address Blacklisting: Your IP may be flagged or blocked by the server due to spam protection mechanisms.
