Microsoft Updates change Default Email Client

We have a WSUS server that updates all of the computers on the network. Problem that we experience is that when the server updates these computers, Lotus Notes is changed from the default email program. Is there a way to hard-code Notes as my default email program so that I wouldn’t have to change it on every single computer on the domain? Changing Notes to be my default email program on 100 computers becomes too tiresome and I do not think that I should have to do this on all of the computers.

Thanks in advance for any assistance.

Hihad the same problem for years, notes 5, 6.5 and 8.0 with WSUS 2

we have MS office and install the outlook messaging component bits - I think they are required for the “send to email recipient” to work from the MS word excel etc

From experience it always been the MS outlook updates that causes the IE program settings to flip back to MS outlook

So we dont allow MS outlook updates to install from WSUS. We only apply the outlook updates when a machine comes back in for servicing

Not a great solution but it saves us a lot of grief

Haven’t tested it but I think you’ll run into the same problem regardless of the email client you use, eg even if you used thunderbird the ms outlook update would reset the IE programs to outlook

If you are running active directory you could maybe reset the IE programs back to lotus notes via a windows group policy, haven’t tried it myself

Subject: You may reset it back to Lotus Notes programmatically (on Windows Vista/7)

Using IApplicationAssociationRegistration::SetAppAsDefaultAll Method
(IApplicationAssociationRegistration::SetAppAsDefaultAll (shobjidl_core.h) - Win32 apps | Microsoft Learn)

Executed after all MS hotfixes had been applied should do the trick (for 8.5.1 FP1 and higher).

This has also been a struggle for us. Attempts to find ways to prevent this have been fruitless. We thought we had the problem figured out when we looked at the following Internet Explorer configuration INF had a reference to “C:\Notes” for whatever reason: “%PROGRAMFILES%\Internet Explorer\CUSTOM\programs.inf” Correcting this however only mitigated the problem marginally. Windows just will not keep Lotus Notes as the default Mail and Calendaring client!

Subject: …No fix for XP?

Hi guys, Thanks for the responses. So I take it that there is no way to resolve this issue for my windows XP environment?

I was thinking that windows server 2003 or 2008 group policy should be able to accomplish this task or there should be a script that I can use to reset the default program back to Lotus Notes but no luck so far.

Let me know if you guys find anything and I’ll do the same if I find the solution.

Regards…Thanks again.
