Not showing all PST files

Aug 24, 2016 at 5:50 PM
Thanks for the software!

I have installed it on three laptops at a charity I volunteer for. They are all Windows 7 x64 using Outlook 2010 x86. Each laptop has one IMAP account set-up, saving to a .PST, with an additional archive .PST, all on a single profile. Using Backup Add-In v1.6.0.0.

One laptop has no additional Outlook-related software and the Backup Add-In sees both PSTs.

The other two the laptops use Code2's Public Folder Syncing software and have an additional Outlook.pst for this. Your Backup Add-In doesn't display the .PST file for either of these computer's .PSTs that their email accounts use i.e. username@domain (1).pst.
Backup Add-In only displays the Outlook.pst and Archive.pst.

I thought maybe the use of @ or () in the filename may have been the problem, as the "working" laptop doesn't use these, but this is not the case.

Backup Add-In correctly backs up all the .PSTs it can see. I have edited the registry for Backup Add-In and manually added the full .PST path for the "missing" .PST files, and the software backs up the PSTs successfully - but still doesn't display them.

Not sure what else to try to get the UI working so if you could suggest anything it'd be helpful.

IMAP usually saves its email into an ost-file. POP-Accounts are using pst-files.
So either you are using POP with pst-files or IMAP with ost-files.

The backup will work with pst files because IMAP accounts are server based and local ost file will only cache the data.
Furthermore ost-files are not suitable for backing up.
