Too many folders in Outlook - Microsoft Community

hi,

we've come across few users. outlook has maximum number of 500 folders before users may start issues;

https://support.microsoft.com/en-gb/help/2768656/outlook-performance-issues-when-there-are-too-many-items-or-folders-in

this comes when user wants use outook filing system , invariably results in users having 2-3,000 folders. question is, best way resolve issue individual users want use outlook in way?

would benefit create local outlook data file archiving , move folders there? office 365 archiving around issue? ideally solution needs specific individual users we're not keen on implementing document management system instance.

thank help.

hi john,

 

based on experience, think can ask user change cache mode 3 months (the default 12 months). can follow steps manage cache mode:

1. open outlook , click file > account settings > account settings.
2. choose account , click change.
3. under offline settings, adjust cache mode 3 months.
4. exit, restart outlook.

 

besides, if users have exchange online or office 365 plans, user can use online archiving. cloud-based, enterprise-class archiving solution. here details. please check if users’ plan include exchange online archiving. if so, need enable archive mailbox.

 

i hope , please let me know if there update.

 

regards,

carlos
