Hi,
I have an add-in for Outlook 2010. On most computers it runs fine, but for one particular customer, the load time of the add-in is extremely slow (10-12 seconds for the add-in, where everyone else have < 2 seconds for the same).
I've been trying to track down why that particular customer experiences this issue.
I had access to two computers: 1 desktop running Win7 and one server running Win2008r2 and Terminal Services - both had the problem of slow loading.
So far I've found this:
I re-installed my add-in on the server. This fixed the issue on the server. But only for my account. Other accounts still had slow load times.
I re-installed my add-in on the desktop, but that didn't change anything.
I then loaded SysInternals Process Monitor from Microsoft, to see what happens when Outlook starts and loads my add-in. I found that on several occations, it paused for 2 seconds, totaling more than 7 seconds of pausing. All pausing happens immidiately after working with the register key "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections" (my add-in does not use that key, so I'm assuming it's something Outlook needs or some inner working of some .NET assembly in my add-in needs).
I wasn't able to Google anything relevant regarding Outlook and that registry key, so I tried to delete it and restart Outlook. This did not change anything, as the keys were just recreated (could be Outlook, could be Windows).
I then disabled my add-in to see if Outlook used the registry keys, or it was only my add-in, and restarted Outlook. Outlook then loaded fast, and I found no reference to the key.
I then enabled my add-in, to see what happens when it's enabled while Outlook is running. This ran fast and did not pause at any time.
I then restarted Outlook (with my add-in enabled), and to my suprise, Outlook loaded fast, and my add-in was loaded in the expected < 2 second timeframe. And I havn't been able to reproduce the slow load times on that desktop (though I havn't tried other users on it).
I will try to see if I can repeat this on the server and possibly on other desktop computers. Or using other users.
Unfortunately I did not save a copy of the adxloader.log file for this computer. I will get one from another computer that display the issues.
As mentioned, the same add-in runs perfectly at all other customers, and with the same OS and Office version, so on the surface there is nothing special about this particular customer.
But do you have any idea to what could have caused the experienced issue? and/or what to look for or configure?
Regards

I logged on with another user on the server, and it was slow (so one user fast, one user slow on the same machine).

Interesting: I then restarted Outlook, and now it was fast (< 2 sec again).
Not sure what happened here, but it is now fast for both users.
I will continue investigating, but all hits, suggestions and ideas are welcome. |

Hi Eugene,
it was the check for publisher's certificate revocation setting that was the issue. Thanks for the help :-)
