Veeam for Microsoft 365 “Item may have a virus reported by the virus scanner plug-in” warning

Share This Post

Veeam will report when an “Item may have a virus reported by the virus scanner plug-in.” This warning is caused when Veeam for M365 attempts to backup an item that the built-in Microsoft 365 virus protection has flagged as possibly being infected. If you were to attempt to download the file that is reporting the malware/virus you should be met with a “This file is compromised” message:

It is recommended that you get your security team involved to investigate if the item has been compromised. Additionally, removing the infected item will clear up the warning in Veeam for M365.

Additionally information on Microsoft built-in virus protection can be found HERE.

If the item that is reporting as potentially having a virus is downloadable and found to be a healthy file, please reach out to and we can assist in investigating the issue.
