Duplication of appointments in shared calendar

[Toltec Support]

Hi,

If all appointments duplicate in a folder it is one of two issues.

First possibility is that the main users PST is corrupted. Please run a
SCANPST.EXE on the PST file.

Second possibility is that the UID Validity of the mailbox on the IMAP4
server keeps changing. This can happen for a number of different reasons,
please have a look at your Cyrus log files.

Best regards
