Exchange 5.5 error

You might want to contact Microsoft direct. Some times it's worth the price. A link that might help as well:

For an explanation of what -1019 is see Technet Article Q184209. This article recommends contacting Product Support for assistance.

Product Support may have you run Exmerge to pull out the data, recreate the private store and then use exmerge once again to push the data back in. For info on how to do this see Technet Article Q259688. Follow these steps completely, it can be a trciky operation. Also as a good measure I'd make sure I have a backup copy of the database just in case, even if theedb is 'broken' its better to have something to fall back on then nothing at all.

Finally, be warned that using Exmere may cause problems and it is recommended to search the knowledge base on Exmerge for the various articles available or call Product Support for information on any problems you may face.
