outlook 2003 'the operation failed'


I am having this issue where multiple PC's on the network are unable to get into outlook 2003 sometimes. they click it and it says 'the operation failed'

if I keep clicking it, eventually it goes in, works fine and all functions are fine.

I have re-installed office and this still makes no difference.

I have disabled add-ons with no luck either.

it wasn't happening a few days ago, now a fair few PC's are affected.

Anything in the event log for either system or application? I would run a disk clean up and malware check on system.

Mainly this type of problems occurs if Exchange Server 2003 Administrative Tools and Outlook 2003 are installed on the same computer. Please check once.

@tmoore1962 nothing in event viewer, im not going to run a disk clean up and malware check because multiple machines are having the problem and a couple of the PC's are brand new and only just been put on the network.
@Shewta Goel I haven't got that installed on my PC.

Open in new window

I found out what this was! Outlook is running in cached mode and if outlook is running in the background it doesn't let you re-open it.

for example: if I close outlook and look in the icon tray it is still there caching. once the icon disappears you can click into outlook!

Resolved but thanks for the help
