4. Support / FAQ No. 04
February 2018: Can´t connect to server. "The RPC server is unavailable". What can I do? (generally information)?
First we must clarify some general points before we can answer spezial points (error numbers):
How old is your Public ShareFolder installation / version? If you are not sure to have the actual version, please use the newest version.
Do you have any kind of an additional Firewall installed?
If yes, please deactivate the additional Firewall, only to test if you get a connection now.
Please test the network connection with the “Ping” COMMAND:
Start/Run and type CMD. In this DOS Windows® type in “PING name of the serve/client”
Is a "ping" from the client to the server successful? (Use the name of the server and not the IP address)
Is a "ping" from the server to the client successful, too? (Use the name of the client and not the IP address)
Is the IP-address correkt, which the ping returns?
More information about the ping command: https://www.computerhope.com/pinghlp.htm
For Windows 10 (1709) users: "“Cannot expand this folder. You don’t have appropriate permissions to perform this operation”.
Please uninstall in Updates the "KB4056892",
KB4056890 or KB4056891.

Do you get any error message number like: The RPC server is unavailable 80070005 or 800706ba?
Please have y look to the FAQ No. 9 or 10.
Check your Outlook® profiles:
Please check in the Control Panel under “Mail” (doubleclick) /Profiles: Do you have installed more than one profile? If you have more than one profile installed, delete no more necessary profiles.
Use of copied PST files:
Is the PST of the server Outlook® the copy of a PST of a Clients? Is it not a new PST file, but the file copy of a Client Outlook®? Please do not use Public ShareFolder with copies of PST files. Please test it again with new created profiles and PST files. If a PST file is curropted or demaged, Public ShareFolder can not repair this, and you wouldn’t get a shared connection with a damaged PST file or with a copy of a PST file.
New register of the "Mapi (Outlook®) interface":
This registration is only possible if no application accesses the Mapi interface. Terminate please first all Mapi (Outlook®) applications like: Outlook®, Public ShareFolder, Word, Excel® etc.
If you are not sure, which programs are using the MAPI interface you can also logoff from your PC, login with your normal account and start the fixmapi.exe:
Search on your local harddisk for "Fixmapi.exe" (C:\Windows\... or C:\WINNT\...) and start it with a doubleclick.
You wouldn't get any feedback. In the background the Mapi interface is new registered. Reboot the computer and check the connection again.
Maybe your PST file is damaged.
Please search for "scanpst.exe" on your local PC. Start this program and select your PST to check the PST file.
Information: Please make a copy of your PST file (Backup) before you start the "scanpst.exe" program.
