Outlook plugin disabled - Add-in Express .NET forum

Hello,

We have noticed multiple instances where the outlook plugin has gotten disabled. We found it was because the plugin took enough time to load, to eventually slow down the outlook loading time. Kindly suggest what needs to be done to ensure that this doesn't happen.

For your information:
1. Our plugin dll is digitally signed.
2. Loader version: 7.5.4072.0
3. Last loader log file generated in one of the computers where the plugin is disabled:

Hello Rohit,

I see two time gaps:
- the add-in spends a second to check the .NET Framewrok version, to start CLR and create an AppDomain
- another second is required to create an instance of the add-in module

I suggest that you check if the same time gaps exist if you create a new empty add-in project.

Because your add-in loads slowly? Or because your add-in slows down switching between folders? Could you please specify?

Are there other add-ins enabled when this issue occurs?

Hello Andrei,

Thanks for your prompt reply

Because your add-in loads slowly? Or because your add-in slows down switching between folders? Could you please specify?

Well, the message outlook displayed was:
User added an image

And while investigating other computers where the plugin is disabled, we came across this event which says outlook plugin took longer than expected to disconnect.
User added an image

And in this computer, other add-ins which were loaded by outlook when the plugin was last loaded successfully are depicted in the following log:

Testing with empty add-in project would not be possible in the customer environment (where the issue has been noticed) for us. Plus, the behavior has not been consistent and once manually enabled, plugin has again loaded successfully. So, we might not be able to draw a conclusion on testing with an empty add-in project.

Hello Rohit,

The Add-in Express loader - which is a COM Office from the viewPoint of Office - does close to nothing in the events that Outlook uses to measure the load time. It actually loads your add-in - and this may take a lot of time - in another event(s) that Outlook doesn't use for load time measurements.

Still sometimes I saw Outlook suggesting disabling an Add-in Express add-in. I have an impression that in this case something slows down *all* of the add-ins loading in this Outlook session; the impression may be wrong. Anyway, I have never been able to reproduce this issue.

In your case, will you be able to study the system logs in order to find out any extra detail about the situation(s) in which your add-in gets disabled?

Hello Andrei,

We would check for extra details and let you know if anything comes up.

Meanwhile wanted to confirm whether it could be because of certificate revocation check? As our plugin is digitally signed. If yes, then how can we identify if it is the reason and what should we do to handle it?

Also, would the possibility of add-in getting disabled minimise if we update the loader to its latest version? Our current version is 7.5.4072.0.

I know that the certificate revocation check added to the load time when you used .NET 2.0. Find extra info in section Delays at add-in start-up at https://www.add-in-express.com/docs/net-tips.php#delays.

I don't think so.
