We recently upgraded the whole company to outlook 2010 and in conjunction with this installed 6.6.2 but now we are seeing increasing numbers of people unable to resolve shortcuts.

Specifically shortcuts which were migrated from emailXtender to Sourceone 6.6 and then upgraded.  We didn't see any problems before the office upgrade.  I've opened a support call but wondered if anyone else has seen this.

Specifically some errors seem to be coming up and are baffling me.

Compete uninstalls of the addin and upgrading to offline access 6.7 have failed to fix it as have reinstalls of office.

Any ideas?
