If you're inbox is a mess this Monday, you're not alone. Microsoft Outlook users have been complaining online about an apparent issue with their junk filter, meaning they've been flooded with spam that usually gets redirected.

Twitter user @bdsams posted what appeared to be his inbox, for instance, and it was chock full of patently obvious junk. We're talking email addresses composed of random numbers, fake security messages, and obvious phishing attempts.

It's unclear what is causing the issue or when it might be resolved. Mashable has reached out to Microsoft for clarification and further details, but did not immediately hear back. We will update the story with comments from the company or when necessary.

Wrote British author and historian Hallie Rubenhold on Twitter, "I'm being bombarded. Someone, please make it stop!"

Keeping a tidy inbox can be crucial for folks, especially when it comes to their working life. Hopefully, there will soon further details and some kind of fix for the apparent issue.
