Accessing email public folders

Its been a long time since I’ve done on-prem email automation, but I’ll share what I remember about public folders and private folders.

Private folders and all other subfolders associated with the mailbox are reachable by paths.  “inbox/subfoldername/subfoldername”.  No issues doing this pattern anywhere.

For public folders, that pathing won’t resolve when connecting with EWS.  POP3 won’t let you see public folders at all, and IMAP has its own nuances around it (must be turned on).  

For it to work with public folders, there’s a required EWS function that I don’t believe we support.  You have to manually do some functions to get the folder IDs, and then connect to those IDs.  Looking at our email package, we dont seem to support browsing folders by IDs, only names.

​@Aaron.Gleason, have you seen this use case before?
 

​@Matt.Stewart I have not, but a quick search shows that public folders start from “PublicFoldersRoot”.

From there, you may have to engage the EWS API to use the FindFolder, GetFolder, FindItem, and GetItem actions because there is no direct path. You have to walk the tree level-by-level. ​@cgillies 

​@Matt.Stewart  & ​@Aaron.Gleason , guys so much for your help, I had not tried the EWS API but it's worth a shot. I tried using Outlook from the email action but it was SLOOOOW. 

Cheers,
