Tasks show up 500+ years in the future

[Allyn]

I have a client who had the same problem on both his old laptop and his brand
new workstation. The laptop was running XP with Office 2003 and was fully
patched. About 8-10 months ago, several of his Outlook Tasks jumped several
hundred years in the future. I thought it must be malicious software. At that
time the systems were protected by Symantec Corporate and had the latest
definitions. His system was running Windows Defender, but I also ran
malwarebytes which didn't turn up anything. He manually corrected the dates -
he has a lot of tasks, so this was quite a process.

Things have been running just fine. Tuesday of this week I upgrade him to a
new workstation running Vista and Office 2007 - again fully patched. A month
or so ago, I upgrade antivirus to TrendMicro. When I install his laptop, I
imported his old PST from Office 2003 into the PST created by Office 2007
using File | Import. Two days went by just fine, but he came in this morning
only to find his tasks moved several hundred years in the future. The system
clock showed correct both times.

I have an aggravated client that wants to know what is happening and how not
to let it happen again. I've been doing this several years, and he is the
only one I've seen this on, so I'm at a loss. Has any one else experienced
this and figured out what is going on?

Thanks

Does this person perhaps sync Outlook with a mobile device?

As an FYI: there was no need to import his pst-file at all. Save yourself
some time by simply reconnecting it via;
File-> Open-> Outlook Data File...
This will also make sure that the client doesn't lose any meta data and
settings which are also kept in the pst-file.

Yes, he does have a Blackberry.

I just talked to my client, and he did sync his Blackberry last night. FYI, I
synced it Tuesday after I installed Office, ran updates, and rebooted. I
think you're onto something here, but I'm at a loss as to what to do next.

Have him check all settings and time values on the Blackberry.
