The MerciApp add-in for Outlook relies on features made available to developers by Microsoft, the publisher of the target software. Unfortunately, Microsoft is aware of certain anomalies and is still working to correct them, making some features unavailable through our add-in or causing different behaviors in some cases.

My email is not analyzed automatically on macOS

Retrieving the content of your email requires a proprietary solution provided by Microsoft that we do not control. Unfortunately, this solution causes a slowdown each time it is used; since automatic analysis requires us to retrieve content at regular and frequent intervals, the writing experience was significantly compromised.

We therefore decided to offer manual analysis instead. Once you have written your email, or whenever you have doubts about a sentence or paragraph, click on the Analyze button at the top of the MerciApp add-in pane. Alerts will appear below within a few moments, as on other platforms.

Applying a suggestion breaks the formatting of my email on macOS

Modifying the content of your email requires a proprietary solution provided by Microsoft that we do not control. To date, this feature has not yet been finalized and cannot handle certain formatting elements.

Among the elements identified are:

• numbered or unnumbered lists,
• images embedded in the body of your email that have been edited in Outlook (e.g., cropping).

If the situation changes in this regard, this article will be updated.

I have noticed another issue

Please let us know by clicking on the Share feedback button at the bottom of the MerciApp add-in pane, or by using the chat feature on our website. Our teams will get back to you with a solution or possibly a request for additional information in order to correct this issue.
