Outlook Could not install the custom actions. The object could not be found

By mamies ·
A few of our admin staff where greeted with a nasty little error on their outlook 2007 today.

When someone tried to open emails or create new ones this error would generate.

How i worked around it was i deleted the FORMS folder. It is located at C:\Documents and Settings\(username)\Local Settings\Application Data\Microsoft\FORMS and contains the file FRMCACHE.DAT.

This was on an XP machine so vista will be a little differant and i also had to unhide the system files to find it. Once it was deleted i restarted Outlook and it works again.

Still could not install the custom actions.

I have deleted the Forms folder and verified through search that FRMACACHE.DAT file does not exists but problem still occurs. Even uninstalled Office and reinstalled and still have the problem. Are there any other issues that may cause this condition?

Same issue here

I have also done this repeatedly, and to no avail, the error keeps returning. I did the uninstall and reinstalled. I also checked through the registry and found a registry key pointing to a form template that no longer existed. I removed this registry and I was hoping that would do it, but sure enough, two or three days later the error returned. The user did inform me that at one point the error returned after he restarted his machine to finish installing updates. This is very frustrating....

Same issue

I get the same issue. This only happens after a user logs into our citrix environment and then back into a XP machine. The FRMCACHE.DAT file is what needs to be deleted out of that FORMS folder. I still have not found a permenant fix for this.

I have done the same thing and the 'fix' works for a while. Then, it comes back and rears its ugly head again. So, what's the permanent fix for this?

Did you ever find the root cause and a permanent fix for this? We have been running into this in our environment too....

Repost as 'Q&A'

Instead of appending a question to an out-of-date discussion, try reposting your problem in the 'Q&A' forum. The 'Discussion' forum is for matters of general discussion, not specific problems in search of a solution. The 'Water Cooler' is for non-technical discussions. You can submit a question to 'Q&A' here:;content

There are TR members who specifically seek out problems in need of a solution. Although there is some overlap between the forums, you'll find more of those members in 'Q&A' than in 'Discussions' or 'Water Cooler'.

Be sure to use the voting buttons to provide your feedback. Voting a '+' does not necessarily mean that a given response contained the complete solution to your problem, but that it served to guide you toward it. This is intended to serve as an aid to those who may in the future have a problem similar to yours. If they have a ready source of reference available, perhaps won't need to repeat questions previously asked and answered. If a post did contain the solution to your problem, you can also close the question by marking the helpful post as "The Answer".
