Fyxer works across most versions of Outlook, but performance depends on which version you're using.
Supported Outlook versions
Best performance:
Outlook Web (browser-based) – highly recommended
New Outlook for Mac or Windows – stable and reliable
Outlook Desktop (Mac) – fully supported
Functional, but less reliable:
Classic Outlook (legacy desktop version for Windows) – works for some features, but can be less stable
Not supported:
Apple Mail (macOS/iOS Mail app)
Third-party clients (e.g. Thunderbird, Notion Mail, Spark, Superhuman)
On-premise or hybrid Exchange servers (limited API support)
💡 Tip: If you're unsure which version you're running, try switching to Outlook Web for the smoothest experience.

Known limitations in Classic Outlook
There are some cosmetic and workflow behaviors to be aware of. None affect email delivery, content, or Fyxer's core functionality.
Issue | Impact | What's happening |
Signature images not loading in the preview pane | You may see a red cross in place of signature images when previewing an email. | This is a cosmetic issue on your side only – recipients always see the full, correctly rendered signature. Double-clicking to open the email fully will also load the signature correctly for you. |
Extra spacing in email threads | When Fyxer generates a draft in an existing thread, previous emails in the thread may display with additional spacing in the preview pane. | This is a visual quirk only and doesn't affect sending, delivery, or how the recipient sees the thread: the content of all emails is completely unchanged. |
Attachments not visible when a draft is active | In conversation mode, attachments aren't visible in the preview pane while a draft is active on a "To do" email. | This is a preview pane limitation in Classic Outlook – the attachment and email itself are unaffected. To view the attachment, discard the draft, open the attachment, then return to re-access the draft. |
Font settings not saving in drafts | When editing a draft in Classic Outlook, font changes, such as size, family, or color, may not save as expected. | This is a Classic Outlook compatibility limitation. To avoid it, edit and send drafts in Outlook Web or New Outlook, where font settings save correctly. |
💡 Tip: switching to Outlook Web or New Outlook avoids all of these limitations.
Troubleshooting and tips
If Fyxer's categories don't appear, check that conversation view is turned on
For duplicate or reappearing archived emails, make sure you've disabled Focused Inbox
If performance is inconsistent, switch to Outlook Web for best results
