Outlook 2010
Exchange 2010

I'm troubleshooting a delay with an Outlook add-in and in discussing the issue with the add-in vendor support, the available information/symptoms suggest that MAPI call response times may be sluggish. How can I measure MAPI response times (independently)? It doesn't have to be the exact same MAPI commands but I'd like to run some general tests.

I was thinking I could use rpcping but information on this tool is a little sparse and I wasn't sure what syntax I should use to test connectivity.

  • Look at the connection status with and without the add-in enabled? – joeqwerty May 19 '15 at 19:08
  • @EEAA Sorry for not mentioning earlier. MAPI communication in my environment is encrypted so it's not easy for me to see when specific requests begin/end. – Mike B May 19 '15 at 22:25
  • @joeqwerty I assume you're referring to the `Avg Resp` column values? That might work, but what exactly is that measuring? From what point to what point? If I'm using RPC/HTTP would that be the response back from the proxy? Or from Exchange? – Mike B May 21 '15 at 01:16
  • Does it matter? The only thing changing is whether or not the add-in being enabled/disabled makes any difference. It's irrelevant what the endpoint is as that's not changing and that's not what you're testing. You're testing the add-in, not the connection endpoint. In effect, the connection endpoint is your "control" regardless of what it is and is a constant for both tests. – joeqwerty May 21 '15 at 01:22

Enable advanced logging in Outlook. Usually RPC trace events help a lot. Do the following:

  1. Disable add-in, collect logs.
  2. Enable add-in, collect logs.
  3. Review the resulting log files.
