FEDB rebuild process

[td1019]

I have a mailbox that has been deleted from the system however when you call the extension and it covers to voicemail the old mailbox answers. The MM system is 5.2 SP 10

I am thinking a FEDB resync might be in order but I have a few questions about this?
I have the following executable in c:\Avaya_Support\Tools\FEDBSync\FEDBSync.exe
Questions -
- I have about 900 mailboxes so how long will this take approximately on one MAS?
- What are the chances that this will not go well and cause the MAS to not recover? I only have one MAS
- If this doesnt work whats the next step?

I have a follow up question is rebuilding the FEDB a different process than just running the FEDBsync.exe?

Follow up ran the resync tool on FEDB with 920 mailboxes and it took less than five minutes. It also seems to have corrected my issue
