If you are experiencing problems with Outlook or are having trouble installing Office apps, Microsoft’s new Office 365 Support and Recovery Assistant tool (aka SaRA) can help diagnose and fix many common user or client side issues.
The tool performs a series of diagnostics tests to help identify the root cause of issues, such as verifying users’ credentials, licenses, updates to Outlook clients, and whether Outlook servers are reachable. Depending on the test results, it can offer to automatically fix problems for users or provide instruction on recommended solutions. All the diagnostics results are saved in a log file for users to share with their Outlook admin or support engineers for further investigation.
Each time we run SaRa, it automatically gets updated to its latest version, so it can troubleshoot any new Outlook problems.
SaRA, still in the pre-release (beta) stage, can be downloaded from this link: http://aka.ms/snrpublic
