Good afternoon, something strange is happening with UiPath, as several functions are unavailable, such as: save mail message and save attachments.
hey @fabiocarra
please check if you don’t have any missing packages like UiPath.Mail.Activities.
Thank you. The package is installed and up to date.
Hi Please try solution mentioned in below post
Basically remove the word “Runtime” from dependencies in project.json and restart UiPath.
can you show some screenshots please..also is it observer across projects? and are there any recent upgrades?
cheers
How do I remove the runtime extension?
Please refer the post I shared above. It shows to remove it from project.json file.
Thank you, but the image only shows the before and after. It doesn’t show the procedure, or at least I can’t see it.
When you open your project json, do you see any dependencies that runtime in the name? Just delete the runtime from the name. Can you show screenshot of your project.json file?
can you go to activities and click on filter and select all that you see there please
cheers
This issue usually happens when the Mail activities package is outdated, corrupted, or not fully loaded. A few things you can try:
- Go to Manage Packages → Official and update the following:
• UiPath.Mail.Activities
• UiPath.System.Activities
If they are already updated, try uninstalling and reinstalling them.
-
Ensure the package version matches your Studio version. Sometimes new package versions hide or remove older activities.
-
Missing or broken dependencies can cause activities to disappear.
Good afternoon, I have already followed all the instructions above and the problem persists. The UiPath version I am using is 2026.0.180.
