Outlook 2016 and later can display the error message "The time limit for logging on was reached while waiting for system resources. Try again. MAPI 1.0 [000004C2]" when starting the application, often causing it to crash immediately after. This issue is frequently associated with the Salesforce for Outlook add-in, outdated software, or problems with system resources. Addressing this error restores the ability to access email and calendar data without interruption, improving workflow efficiency.
Update the Salesforce for Outlook Add-in
Outdated add-ins, especially Salesforce for Outlook, are a common cause of this error. Installing the latest version of the add-in can resolve compatibility issues and restore normal Outlook operation.
Step 1: Download the most recent version of the Salesforce for Outlook add-in from the official Salesforce website. Keeping the add-in current ensures compatibility with Outlook updates and reduces the likelihood of resource conflicts.
Step 2: Install the downloaded update, following the on-screen prompts. If prompted to close Outlook or other applications, do so before proceeding to avoid installation errors.
Step 3: Restart Outlook and check if the error message still appears. If Outlook starts normally, the problem is resolved.
Reinstall the Salesforce for Outlook Add-in and Update Outlook
Uninstalling and reinstalling the Salesforce for Outlook add-in, combined with updating Outlook itself, can address corrupted files or outdated components contributing to the error.
Step 1: Uninstall the Salesforce for Outlook add-in. Visit the Salesforce support site and follow the published instructions to remove the add-in completely from your system.
Step 2: Update Outlook to the latest version. The steps differ depending on whether your Office installation is Click-to-Run or MSI-based:
- Click-to-Run: Open Outlook, go to the
File
menu, selectOffice Account
, then clickUpdate Options
and chooseUpdate Now
. If updates are disabled, enable them first.

- MSI-based: Check for updates on the official Office support page and manually install any available updates for Outlook 2016.
Step 3: Download and install the latest Salesforce for Outlook add-in from Salesforce’s website.
Step 4: Restart your computer, then open Outlook to see if the error persists.
Disable or Remove the Salesforce for Outlook Add-in
If updating or reinstalling the add-in does not resolve the issue, disabling or removing the Salesforce for Outlook add-in can isolate the problem and restore Outlook functionality.
Step 1: Open the Run dialog by pressing Windows + R
on your keyboard.
Step 2: Enter the following command to start Outlook in Safe Mode, which loads Outlook without add-ins:
Outlook /safe

Step 3: In Outlook, click File
> Options
> Add-ins
. Next to Manage COM Add-ins
, click Go
.

Step 4: Uncheck the box next to Salesforce for Outlook
and click OK
to disable the add-in.
Step 5: Close Outlook and restart it normally. If the error is gone, the add-in was the source of the issue. If needed, fully uninstall the Salesforce for Outlook add-in using the official Salesforce instructions.
Restart Your Computer After Updates
In some cases, a simple restart after updating Office 365 or Outlook resolves the error, as pending updates may not take effect until the system reboots.
Step 1: Save your work and restart your computer after installing any Office or add-in updates.
Step 2: Open Outlook again to check if the error message still appears.
Additional Troubleshooting Tips
- If you do not have the Salesforce for Outlook add-in installed, check for other third-party add-ins that might be causing resource conflicts and disable them using the same steps as above.
- Verify that your Office installation is up to date, as outdated versions can introduce compatibility issues with add-ins.
- If Outlook continues to crash, consider repairing your Office installation through the Control Panel or Office settings.
Addressing the "time limit for logging on was reached" error in Outlook involves updating or removing problematic add-ins and keeping Outlook itself current. Restarting your system after updates often resolves lingering issues, allowing Outlook to start reliably again.
