Cannot turn off a reminder in Outlook


We are running Outlook 2007 with Exchange 2003.

A user keeps getting this message:

"Cannot turn off reminder. You maybe reminded again. Out of memory of system resources. Close some programs and try again"

We have run /cleanreminders and also tried logging onto his Outlook on a different machine, still get the error.

Any idea?

If you have OWA you can switch it off from there

Try turning off Cache Mode, then run the /cleanreminders switch again.

You can also try using the Inbox Repair Tool -
Creating Active Directory Users from a Text File

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

Have a look at the following:

Come to think of it .... I have run into this issue before with an Anti-Virus add-in malfunctioning.  I had to uninstall the anti-virus and then use the /cleanreminders switch a couple times before the reminder was correctly repaired.  Then I was able to reinstall my AV.

Since you are getting "Out of memory of system resources" there seems to be memory leak from a program.
