Attachments FAQ and Troubleshooting
🤔What is the maximum size of attachments?
- OUTGOING Email combined file size (across all) attachments is limited to 20 MB. 💡Your local organizational limits set for the mailbox may deviate from this. A popup will inform when this limit is exceeded.
- INCOMING Email attachments have no size limits.
🤔Are attachment checks performed?
☝️ No – aside from displaying links and attachments for download, Nimbus does NOT perform any attachment filtering or checks for malicious files.
✅ As mailbox owner/administrator you need to ensure that according filters and malware checks are applied on the mailbox before reaching the inbox folder.
🤔Are attachments not showing?
💡 If for any reason attachments cannot be shown / downloaded in Nimbus, a message will be shown instead, informing that the attachments should be checked directly in the mailbox.
✅ If you have encountered a use case of clearly non-malicious files which you expect to handle via the Nimbus UI please contact support so we can analyze your case and extend the list of allowed attachments.
